Book excerpt: HERA is the first electron-proton colliding beam facility and the big news about it is that it works, despite concerns both about the reproducibility of the magnetic field in the proton ring magnets at injection and about the e-p beam-beam interaction. It is, however, a complex accelerator facility that will take a few years to bring up to full and efficient operation. With the present center of mass energy of 296 GeV, it extends the energy range for photoproduction studies by an order of magnitude over fixed target experiments and deep-inelastic e-p scattering up to momentum transfer values approaching 105 GeV2 in both neutral and charged current interactions. At reasonable Q2, and so with the present luminosity, events with Bjorken x down to a few times 10−5 are being studied. Two powerful general-purpose detectors -- H1 and ZEUS -- have been constructed to address these physics challenges and both collaborations have made new and interesting measurements as presented at this and other recent HEP conferences. The experimental program started in July 1992 and we are on a steep learning curve both with HERA and with the detectors.

This book was released on 2018-09-13 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding of protons and neutrons, or "nucleons"â€"the building blocks of atomic nucleiâ€"has advanced dramatically, both theoretically and experimentally, in the past half century. A central goal of modern nuclear physics is to understand the structure of the proton and neutron directly from the dynamics of their quarks and gluons governed by the theory of their interactions, quantum chromodynamics (QCD), and how nuclear interactions between protons and neutrons emerge from these dynamics. With deeper understanding of the quark-gluon structure of matter, scientists are poised to reach a deeper picture of these building blocks, and atomic nuclei themselves, as collective many-body systems with new emergent behavior. The development of a U.S. domestic electron-ion collider (EIC) facility has the potential to answer questions that are central to completing an understanding of atoms and integral to the agenda of nuclear physics today. This study assesses the merits and significance of the science that could be addressed by an EIC, and its importance to nuclear physics in particular and to the physical sciences in general. It evaluates the significance of the science that would be enabled by the construction of an EIC, its benefits to U.S. leadership in nuclear physics, and the benefits to other fields of science of a U.S.-based EIC.

This book was released on 1997-10-06 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first five years of operation of the two multi-purpose experiments ZEUS and H1 at the HERA electron--proton storage ring facility in Hamburg, Germany have opened a new era in the study of diffractive vector-meson production in high-energy photon--proton interactions. This book provides readers who have a general knowledge of the concepts and experimental techniques of elementary particle physics with the information necessary to assess the status of the new investigations prior to the end of 1996. The measurements are placed in the rich historical context of earlier studies of photo- and leptoproduction of vector mesons.
Download or read book Beam Measurement written by S. I. Kurokawa and published by World Scientific. This book was released on 1999 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises the proceedings of the 8th Joint School on accelerator physics. On this occasion, the US, CERN, Japan and Russia Particle Accelerator Schools collaborated to present the topic "Beam Measurements." The aim was to provide an introduction to the principles of beam dynamics and measurements in circular particle accelerators. This was achieved by a series of lectures under the heading of "single-particle dynamics," "beam measurements" and then "multi-particle dynamics," along with practical courses on feedback and data processing, maps and simulation, diagnostic and microwave measurements. The resulting proceedings represent a unique summary of the currently available knowledge on beam measurements applied to circular particle accelerators.

Download or read book Charm Production in Deep Inelastic Scattering written by Sebastian Klein and published by Springer Science & Business Media. This book was released on 2011-10-09 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of heavy quarks in high-energy experiments offers a rich field to study, both experimentally and theoretically. Due to the additional quark mass, the description of these processes in the framework of perturbative QCD is much more demanding than it is for those involving only massless partons. In the last two decades, a large amount of precision data has been collected by the deep inelastic HERA experiment. In order to make full use of these data, a more precise theoretical description of charm quark production in deep inelastic scattering is needed. This work deals with the first calculation of fixed moments of the NNLO heavy flavor corrections to the proton structure function F2 in the limit of a small charm-quark mass. The correct treatment of these terms will allow not only a more precise analysis of the HERA data, but starting from there also a more precise determination of the parton distribution functions and the strong coupling constant, which is an essential input for LHC physics. The complexity of this calculation requires the application and development of technical and mathematical methods, which are also explained here in detail.
