This book was released on 2007 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present the first observation of the decay $ar{B}$$0top{s}$ → D$+top{s}$ K∓ and measure the relative branching fraction of $ar{B}$$0top{s}$ → D$+top{s}$ K∓ to $ar{B}$$0top{s}$ → D$+top{s}$ ?-. The measurement of the relative branching fraction is performed by applying a fit in invariant mass and specific ionization to 1.2 fb-1 of Ds(??)X data collected with the CDF II detector in pp collisions at √s = 1.96 TeV at the Fermilab Tevatron collider. We measure B($ar{B}$$0top{s}$ → D± s K∓¢/B($ar{B}$$0top{s}$ → D$+top{s}$ ?-) = 0.107±0.019(stat)±0.008(sys). The statistical significance of the $ar{B}$$0top{s}$ → D$+top{s}$ K∓ signal is 7.9?. To cross-check our analysis method, we also measure B($ar{B0}$ → D+K-)/B($ar{B0}$ → D+?-) and B($ar{B0}$ → D*+K-)/B($ar{B0}$ → D*+?-) and verify that our results are in agreement with the world average.

Download or read book First Observation of Coherent Elastic Neutrino Nucleus Scattering written by Bjorn Scholz and published by Springer. This book was released on 2018-10-26 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the experimental work that finally led to a successful measurement of coherent elastic neutrino-nucleus scattering—a process proposed forty-three years ago. The experiment was performed at the Spallation Neutron Source facility, sited at Oak Ridge National Laboratory, in Tennessee. Of all known particles, neutrinos distinguish themselves for being the hardest to detect, typically requiring large multi-ton devices for the job. The process measured here involves the difficult detection of very weak signals arising from nuclear recoils (tiny neutrino-induced “kicks” to atomic nuclei), but leads to a much larger probability of neutrino interaction when compared to all other known mechanisms. As a result of this, “neutrino technologies” using miniaturized detectors (the author's was handheld and weighed only 14 kg) become a possibility. A large community of researchers plans to continue studying this process, facilitating an exploration of fundamental neutrino properties that is presently beyond the sensitivity of other methods.

Available in PDF, EPUB and Kindle. Book excerpt: The updated and much expanded 3e of the Handbook of Radioactivity Analysis is an authoritative reference providing the principles, practical techniques, and procedures for the accurate measurement of radioactivity from the very low levels encountered in the environment to higher levels measured in radioisotope research, clinical laboratories, biological sciences, radionuclide standardization, nuclear medicine, nuclear power, and fuel cycle facilities and in the implementation of nuclear forensic analysis and nuclear safeguards. The book describes the basic principles of radiation detection and measurement and the preparation of samples from a wide variety of matrices, assists the investigator or technician in the selection and use of appropriate radiation detectors, and presents state-of-the-art methods of analysis. Fundamentals of radiation properties, radionuclide decay, the calculations involved, and methods of detection provide the basis for a thorough understanding of the analytical procedures. The Handbook of Radioactivity Analysis, 3e, is suitable as a teaching text for university and professional training courses. - The only comprehensive reference that describes the principles of detection and practical applications of every type of radioactivity detector currently used. The new 3e is broader in scope, with revised and expanded chapters, new authors, and seven new chapters on Alpha Spectrometry, Radionuclide Standardization, Radioactive Aerosol Measurements, Environmental Radioactivity Monitoring, Marine Radioactivity Analysis, Nuclear Forensic Analysis and Analytical Techniques in Nuclear Safeguards - Discusses in detail the principles, theory and practice applied to all types of radiation detection and measurement, making it useful for both teaching and research

Download or read book The Physics of the B Factories written by Adrian Bevan and published by Springer. This book was released on 2015-03-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive work thoroughly introduces and reviews the set of results from Belle and BaBar - after more than two decades of independent and complementary work - all the way from the detectors and the analysis tools used, up to the physics results, and the interpretation of these results. The world’s two giant B Factory collaborations, Belle at KEK and BaBar at SLAC, have successfully completed their main mission to discover and quantify CP violation in the decays of B mesons. CP violation is a necessary requirement to distinguish unambiguously between matter and antimatter. The shared primary objective of the two B Factory experiments was to determine the shape of the so-called unitarity triangle, an abstract triangle representing interactions of quarks, the elementary constituents of matter. The area of the triangle is a measure of the amount of CP violation associated with the weak force. Many other measurements have been performed by the B Factories and are also discussed in this work.

Book excerpt: We present an observation of the decay B[sup 0][yields][pi][sup 0][pi][sup 0] based on a sample of 124 million B[bar B] pairs recorded by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We observe 46[+-] 13[+-] 3 events, where the first error is statistical and the second is systematic, corresponding to a significance of 4.2 standard deviations including systematic uncertainties. We measure the branching fraction[Beta](B[sup 0][yields][pi][sup 0][pi][sup 0])= (2.1[+-] 0.6[+-] 0.3) x 10[sup -6], averaged over B[sup 0] and[bar B][sup 0] decays.
Download or read book Study of Double Charm B Decays with the LHCb Experiment at CERN and Track Reconstruction for the LHCb Upgrade written by Renato Quagliani and published by Springer. This book was released on 2018-11-04 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the study of double charm B decays and the first observation of B0->D0D0Kst0 decay using Run I data from the LHCb experiment. It also describes in detail the upgrade for the Run III of the LHCb tracking system and the trigger and tracking strategy for the LHCb upgrade, as well as the development and performance studies of a novel standalone tracking algorithm for the scintillating fibre tracker that will be used for the LHCb upgrade. This algorithm alone allows the LHCb upgrade physics program to achieve incredibly high sensitivity to decays containing long-lived particles as final states as well as to boost the physics capabilities for the reconstruction of low momentum particles.
