Book Description
This thesis, which won one of the six 2015 ATLAS Thesis Awards, concerns the study of the charmonium and bottomonium bound heavy quark bound states. The first section of the thesis describes the observation of a candidate for the chi_b(3P) bottomonium states. This represented the first observation of a new particle at the LHC and its existence was subsequently confirmed by D0 and LHCb experiments. The second part of the thesis presents measurements of the prompt and non-prompt production of the chi_c1 and chi_c2 charmonium states in proton-proton collisions. These measurements are compared to several theoretical predictions and can be used to inform the development of theoretical models of quarkonium production.

Book Description
This thesis discusses in detail the measurement of the polarizations of all S-wave vector quarkonium states in LHC proton-proton collisions with the CMS detector. Heavy quarkonium states constitute an ideal laboratory to study non-perturbative effects of quantum chromodynamics and to understand how quarks bind into hadrons. The experimental results are interpreted through an original phenomenological approach, which leads to a coherent picture of quarkonium production cross sections and polarizations within a simple model, dominated by one single color-octet production mechanism. These findings provide new insights into the dynamics of heavy quarkonium production at the LHC, an important step towards a satisfactory understanding of hadron formation within the standard model of particle physics.

Phenomenology Of Ultra-relativistic Heavy-ion Collisions

Phenomenology Of Ultra-relativistic Heavy-ion Collisions PDF Author: Wojciech Florkowski
Publisher: World Scientific Publishing Company
ISBN: 9813107596
Category : Science
Languages : en
Pages : 437

Book Description
This book gives an introduction to main ideas used in the physics of ultra-relativistic heavy-ion collisions. The links between basic theoretical concepts (discussed gradually from the elementary to more advanced level) and the results of experiments are outlined, so that experimentalists may learn more about the foundations of the models used by them to fit and interpret the data, while theoreticians may learn more about how different theoretical ideas are used in practical applications. The main task of the book is to collect the available information and establish a uniform picture of ultra-relativistic heavy-ion collisions. The properties of hot and dense matter implied by this picture are discussed comprehensively. In particular, the issues concerning the formation of the quark-gluon plasma in present and future heavy-ion experiments are addressed.

B Physics at Hadron Machines

B Physics at Hadron Machines PDF Author: Manfred Paulini

Book Description
This conference series reviews progress in understanding the physics of the 5th quark (beauty quark or bottom quark) and the properties of particles containing a b-quark. These quarks are produced at particle accelerators such as electron-positron accelerators or hadron colliders with the latter being the focus of the conference. One of the main issues in understanding the physics of the 5th quark is CP violation, a mechanism in particle physics that breaks the symmetry of nature between particles and antiparticles ultimately connected to the particle-antiparticle asymmetry of the universe. Topics include: recent results; CP violation; B production and spectroscopy; detectors, hardware, and computing; Vucb, Vub, and factorization; B lifetimes and mixing; rare decays; B trigger at future experiments; B physics at future hadron machines; the future of flavor.
