This book was released on 1975 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors propose to take one million pictures of high energy neutrinos in an approximately 20% mixture of Neon and Helium using the FNAL 15 foot bubble chamber exposed to the quadrupole triplet focused neutrino beam with the EMI. Their experience in E-28A has shown that the capability of recording and analyzing high multiplicity, multiple gamma conversions, secondary neutron interactions, and high energy electrons makes this instrument uniquely useful in searching for new phenomena in neutrino interactions.
Download or read book Probing Particle Physics With Neutrino Telescopes written by Carlos Perez De Los Heros and published by World Scientific. This book was released on 2019-12-23 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the reader to how fundamental topics in particle physics can be studied with the largest neutrino telescopes currently in operation. Due to their large size, reaching cubic-kilometer volumes, and their wide energy response, these unusual detectors can provide insight on neutrino oscillations, dark matter searches or searches for exotic particles, new neutrino interactions or extra dimensions, among many other topics.Lacking a man-made neutrino 'beam', neutrino telescopes use the copious flux of neutrinos continuously produced by cosmic rays interacting in the Earth's atmosphere, as well as neutrinos from astrophysical origin. They have therefore access to neutrinos of higher energies and much longer baselines than those produced in present accelerators, being able to search for new physics at complementary scales than currently available in particle physics laboratories around the world.Written by carefully chosen experts in the field, the book introduces each topic in a pedagogical way apt not only to professionals, but also to students or the interested reader with a background in physics.
Download or read book Search for Populations of Unresolved Sources of High Energy Neutrinos with the ANTARES Neutrino Telescope written by Rodrigo Gracia Ruiz and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astroparticle physics is a branch of physics related to the study of the most violent astrophysical phenomena in the Universe such as Active Galactic Nuclei (AGN) or Gamma Ray Bursts (GRB), which emit different cosmic messengers such as neutrinos, gravitational waves, electromagnetic radiation and charged particles. A proper understanding of these objects involves then a multi-messenger approach, in which neutrinos play a fundamental role. Thanks to their physical properties, neutrinos allow us to explore the physical phenomena produced in the densest astrophysical environments and to observe the Universe at large distances. This thesis is divided into three main parts. The first part is composed by three chapters dedicated to the scientific context in which the rest of the thesis is developed. In the first chapter, the scientific motivations for the search of high energy cosmic neutrinos are described. In chapter 2, a description of the main properties of AGN are given. These sources have been chosen as "test" objects in the research of potential neutrino sources. Finally, the third chapter is dedicated to the detection principle and main results of the currently operating neutrino telescopes. The second part of the thesis is dedicated to the technical description of the ANTARES neutrino telescope, and composed of two chapters. Chapter 4 describes the ANTARES telescope, the data acquisition and the data selection. In the last part of this chapter, the work made to measure the efficiency loss of the photomultipliers (PMTs) by using the baseline rates is described. Chapter 5 is dedicated to the Monte Carlo simulations. The different simulation packages used by the ANTARES collaboration are presented, and the different simulated processes are described. A contribution to the official package for the generation of neutrino interactions, relative to the implementation of the propagation and decay of the tau leptons, is described. The third part is dedicated to the search of potential cosmic signals in the events recorded by ANTARES. It comprises four chapters. Chapter 6 is a description of the signal search method, chapter 7 presents the principles of an analysis based on a 2 point correlation function that will be applied in chapter 9 with the purpose of searching for an excess of cosmic neutrinos characterized by an expected spatial distribution which is different from that of atmospheric neutrinos. This method is well suited for the detection of the collective effect produced by populations of weak point-like sources. Chapter 8 describes the simulation of the neutrino flux emitted by AGN. By using the luminosity function for different AGN classes obtained from X-ray observations, and the ANTARES acceptance, neutrinos coming from AGN populations are simulated as a function of two parameters which are related to the number of sources in the population, and to their luminosities. The analysis of these populations with the 2 point correlation function is detailed in chapter 9.

Book excerpt: A new high-energy neutrino program is described. The experiment would tag and reconstruct semileptonic decays in an intense K/sub L/ beam. The species and energy of outgoing neutrinos would be identified event-by-event and the neutrino interactions recorded in a massive iron detector. Such a system could search new regions in (.delta.m2, sin2 2theta) space for neutrino oscillations with small mixing angles and measure .nu./sub .mu./ and .nu./sub e/ cross-sections to approx. 1%. The system could determine sin2 theta/sub W/ in deep-inelastic scattering off quarks to +-.002--.004, a significant improvement over existing measurements. 17 refs., 5 figs., 2 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: The scientific program of these important proceedings was arranged to cover most of the field of neutrino physics. In light of the rapid growth of interest stimulated by new interesting results from the field, more than half of the papers presented here are related to the neutrino mass and oscillations, including atmospheric and solar neutrino studies. Neutrino mass and oscillations could imply the existence of a mass scale many orders of magnitudes higher than presented in current physics and will probably guide scientists beyond the standard model of particle physics.

Available in PDF, EPUB and Kindle. Book excerpt: Optics of Charged Particles, 2nd edition, describes how charged particles move in the fields of magnetic and electrostatic dipoles, quadrupoles, higher order multipoles, and field-free regions. Since the first edition, published over 30 years ago, new technologies have emerged and have been used for new ion optical instruments like, for instance, time-of-flight mass analyzers, which are described now. Fully updated and revised, this new edition provides ways to design mass separators, spectrographs, and spectrometers, which are the key tools in organic chemistry and for drug developments, in environmental trace analyses and for investigations in nuclear physics like the search for super heavy elements as well as molecules in space science. The book discusses individual particle trajectories as well as particle beams in space and in phase-space, and it provides guidelines for the design of particle optical instruments. For experienced researchers, working in the field, it highlights the latest developments in new ion optical instruments and provides guidelines and examples for the design of new instruments for the transport of beams of charged particles and the mass/charge or energy/charge analyses of ions. Furthermore, it provides background knowledge required to accurately understand and analyze results, when developing ion-optical instruments. By providing a comprehensive overview of the field of charged particle optics, this edition of the book supports all those working, directly or indirectly, with charged-particle research or the development of ion- and electron-analyzing instruments. Provides enhanced, clear descriptions, and derivations making complex aspects of the general motion of charged particles understandable as well as features of charged particle analyzing instruments Assists the reader in applying insights obtained from the principles of charged particle optics to the design of new transporting and mass- or energy-analyzing instruments for ions Discusses new applications and newly occurring issues, which have arisen since the first edition
Download or read book Radiative Processes in Astrophysics written by George B. Rybicki and published by John Wiley & Sons. This book was released on 2008-09-26 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiative Processes in Astrophysics: This clear, straightforward, and fundamental introduction is designed to present-from a physicist's point of view-radiation processes and their applications to astrophysical phenomena and space science. It covers such topics as radiative transfer theory, relativistic covariance and kinematics, bremsstrahlung radiation, synchrotron radiation, Compton scattering, some plasma effects, and radiative transitions in atoms. Discussion begins with first principles, physically motivating and deriving all results rather than merely presenting finished formulae. However, a reasonably good physics background (introductory quantum mechanics, intermediate electromagnetic theory, special relativity, and some statistical mechanics) is required. Much of this prerequisite material is provided by brief reviews, making the book a self-contained reference for workers in the field as well as the ideal text for senior or first-year graduate students of astronomy, astrophysics, and related physics courses. Radiative Processes in Astrophysics also contains about 75 problems, with solutions, illustrating applications of the material and methods for calculating results. This important and integral section emphasizes physical intuition by presenting important results that are used throughout the main text; it is here that most of the practical astrophysical applications become apparent.

Download or read book A Search for Displaced Leptons in the ATLAS Detector written by Lesya Horyn and published by Springer Nature. This book was released on 2022-02-07 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a search for long-lived particles decaying into displaced electrons and/or muons with large impact parameters. This signature provides unique sensitivity to the production of theoretical lepton-partners, sleptons. These particles are a feature of supersymmetric theories, which seek to address unanswered questions in nature. The signature searched for in this thesis is difficult to identify, and in fact, this is the first time it has been probed at the Large Hadron Collider (LHC). It covers a long-standing gap in coverage of possible new physics signatures. This thesis describes the special reconstruction and identification algorithms used to select leptons with large impact parameters and the details of the background estimation. The results are consistent with background, so limits on slepton masses and lifetimes in this model are calculated at 95% CL, drastically improving on the previous best limits from the Large Electron Positron Collider (LEP).
