Book Description
This dissertation describes the first CP asymmetry parameter sin(2[beta]) measurement by the DO collaboration, sing the opposite side jet charge tagging algorithm in determining B-flavor. The time integrated measurement yields sin(2[beta]) = 0.82 ± 1.80, and the time dependent measurement gives sin(2[beta]) = 1.80 ± 1.15.

Book Description
We present a measurement of the time-dependent asymmetry in the rate for [anti]B[sup 0][sub d] versus B[sup 0][sub d] decays to J/[psi] K[sup 0][sub S] . In the context of the Standard Model this is interpreted as a measurement of the CP-violation parameter sin(2[beta]). A total of 198 [+-] 17 B[sup 0][sub d]/[anti B][sup 0][sub d] decays were observed in p[anti p] collisions at ps = 1:8 TeV by the CDF detector at the Fermilab Tevatron. The initial b-flavor is determined by a same side avor tagging technique. Our analysis results in sin(2[beta]) = 1:8 [+-] 1:1(stat) [+-] 0:3(syst).

Book Description
This thesis presents a measurement of the time-dependent asymmetry in the rate of[anti B][sub d][sup 0] versus B[sub d][sup 0] decays to J/[psi]K[sub s][sup 0]. In the context of the Standard Model this is interpreted as a measurement of the CP violation parameter sin(2[beta]). A total of 198[+-]17 B[sub d][sup 0]/[anti B][sub d][sup 0] decays were observed in p[anti p] collisions at[radical]s=1.8 TeV by the CDF detector at the Fermilab Tevatron. The initial B flavor (whether B[sup 0] or[anti B][sup 0]) is determined by a same-side flavor tagging technique. The analysis results in sin(2[beta])=1.8[+-]1.1(stat.)[+-]0.3(syst.). This analysis demonstrates the feasibility of studying CP violation in the B[sup 0]-[anti B][sup 0] system at a hadron collider. By applying the methods used in this analysis, future, higher-statistics experiments should be able to tightly constrain the parameters of the Standard Model.

Book Description
In the 110 pb[sup -1] Run I data sample, using three complementary flavor-tagging algorithms CDF has made a new measurement of the CP-violating asymmetry sin(2[beta])=0.79[sup +0.41][sub -0.44], This corresponds to the limit sin(2[beta])>-0.08 at 95% confidence level. This result agrees well with predictions from indirect constraints based on fits of elements of the CKM matrix.

Book Description
The traditional purpose of the Adriatic Meeting is to present most advanced scienti?c research conducted by the lecturers who take part in the development of their ?elds and, in addition, to provide a school-like atmosphere for young scientists. Dubrovnik, as a geographical centre of this region of Europe, provided a most adequate location for this conference. Having very agreeable surroundings, the conference site nevertheless gave a focus for very strong scienti?c interaction. The subjects chosen for the 8th meeting, in September 2001, were gauge theories, particle phenomenology, string theories and cosmology. We were able to bring together a very good cross section of outstanding scientists who gave extraorinarily good presentations. Certainely one reason for this success is that most of us feel obliged to help the scienti?c life in South East Europe return to its former level. However, there are very exciting new scienti?c developments as well. Part of the meeting was dominated by neutrino physics which has just seen exciting progress by establishing neutrino masses experimentally. This was d- cussed within neutrino masses and grand uni?ed theories (GUTs). General - pects of neutrino physics and CP violation, neutrino mixing and the bayron asymmetry were presented along the same lines. On the theoretical side the idea of the construction of gauge theories on non-commutative spaces and their phenomenological implications is accepted worldwide within the particle physics community.

Book Description
This second open access volume of the handbook series deals with detectors, large experimental facilities and data handling, both for accelerator and non-accelerator based experiments. It also covers applications in medicine and life sciences. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access

Selected Exercises in Particle and Nuclear Physics

Selected Exercises in Particle and Nuclear Physics PDF Author: Lorenzo Bianchini
Publisher: Springer
ISBN: 331970494X
Category : Science
Languages : en
Pages : 374

Book Description
This book presents more than 300 exercises, with guided solutions, on topics that span both the experimental and the theoretical aspects of particle physics. The exercises are organized by subject, covering kinematics, interactions of particles with matter, particle detectors, hadrons and resonances, electroweak interactions and flavor physics, statistics and data analysis, and accelerators and beam dynamics. Some 200 of the exercises, including 50 in multiple-choice format, derive from exams set by the Italian National Institute for Nuclear Research (INFN) over the past decade to select its scientific staff of experimental researchers. The remainder comprise problems taken from the undergraduate classes at ETH Zurich or inspired by classic textbooks. Whenever appropriate, in-depth information is provided on the source of the problem, and readers will also benefit from the inclusion of bibliographic details and short dissertations on particular topics. This book is an ideal complement to textbooks on experimental and theoretical particle physics and will enable students to evaluate their knowledge and preparedness for exams.
