Description
In nature, quarks cannot exist by themselves . When produced, like for example in high energy collisions, quarks join together with other quarks to form hadrons. This process, called hadronization, is driven by the strong force (QCD) and is yet not fully understood. Measurements of B mesons at colliders offer unique probes of the hadronization process by which single quarks form color-neutral hadrons.
%The aim of this thesis is to study B mesons (in specific $B^+$, $B^0_s$ and $B^0$ mesons) in pp collisions, exploring the 2017 datasets collected from the CMS experiment at the LHC. By analysing the different meson signals and measuring their relative cross sections, unique sensitive observables become available.
%This work will be performed by exploring dependencies in B mesons kinematics (like transverse momentum and rapidity) as well as environmental observables (like charge multiplicity). The results will then be compared with theory predictions involving relevant hadronization mechanisms, as well as with corresponding measurements performed in heavy ion collisions, allowing us to potentially enhance significantly our current understanding of underlying QCD mechanisms, both in the vaccuum and in the presence of hot QCD matter (QGP).
