First Observation of Fully Reconstructed B0 and Bs0 Decays into Final States Involving an Excited Neutral Charm Meson in LHCb


Book Description

This book presents the latest results on the branching fraction and phase space distribution of B0 and Bs0 decays into final states including excited neutral charm mesons. This work represents four years of research, and the book describes in detail all the necessary steps and techniques required to perform a physics analysis of the data recorded by the LHCb experiment in the years 2016–2018. Although the results presented in this book represent the first measurement of such decays, the text is written in a manner accessible to Ph.D. students and early career researchers. Thus, all the contents included in this book are described in a pedagogical way, including technical details that would allow the results to be reproduced in future. In addition to the methodology used to perform these measurements, the book also includes a description of the theoretical background required to interpret the results presented, as well as a technical description of the LHCb detector, which provided the data sample used in this study.













Multiparticle Correlations And Nuclear Reactions, Corinne Ii


Book Description

This conference brought together the people working on 4π detectors to discuss what had been achieved, whether the results agreed, and to think about possible collaborations to measure the excitation function of several observables. It discussed the similarities and differences in the results obtained at low (100 MeV-1 GeV) and high (10 GeV-200 GeV) energies and outlined what the different fields could learn from each other, especially concerning correlations and particle production. It surveyed the success and also the insufficiency of the present theoretical approaches and discussed the direction in which they have to improve. Finally it gave an account of new developments in data analysis (wavelets, neural networks etc.).




Study of Double Charm B Decays with the LHCb Experiment at CERN and Track Reconstruction for the LHCb Upgrade


Book Description

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.







Calorimetry In High Energy Physics - Proceedings Of The 2nd International Conference


Book Description

This volume is an almost exhaustive review of what physicists are doing (and intend to do for the future hadron colliders LHC and SSC) in the field of calorimetry in high energy physics.It is divided into two parts. The first comprises a series of invited papers which illustrate the state of the art in the field. The second is made up of contributed papers on calorimetry for LHC and SSC.




Studies of CP-Violation in Charmless Three-Body b-Hadron Decays


Book Description

This book highlights two essential analyses of data collected during the LHCb experiment, based on the Large Hadron Collider at CERN. The first comprises the first observation and studies of matter-antimatter asymmetries in two three-body b-baryon decays, paving the way for more precise measurements of the relatively unknown decay properties of b-baryon decays. The second is an analysis of a charged B meson decay to three charged pions, where previously large matter-antimatter asymmetries were observed in a model-independent analysis. Here a model of the decay amplitude is constructed using the unitarity-conserving ‘K-matrix’ model for the scalar contributions, so as to gain an understanding of how the previously observed matter-antimatter asymmetries arise; further, the model’s construction yields the most precise and comprehensive study of this decay mode to date.
