In proton--proton collisions, the measurements of beauty-hadron production cross sections are an effective tool to test the perturbative QCD (pQCD) calculations. In addition, they provide the required reference for measurements performed in Pb--Pb and p--Pb collision systems, in order to study the in-medium mass dependent energy loss and the possible effects of cold nuclear matter,...
Open heavy-flavour hadrons are one of the the key diagnostic tools available to study the dense, hot strongly interacting matter formed in relativistic heavy-ion collisions. The charm and beauty quarks are produced at the early stages of the collision via hard scattering due to their large bare masses, which exceed the QCD scale parameter ($\lambda_{\text{QCD}}$) significantly. In pp...
Measurements of heavy-flavours tagged jets and heavy-flavour particle azimuthal correlation with charged particles allow for comparisons of the heavy quarks (charm and beauty) production, propagation, and hadronization across different collision systems. The measurement of heavy-flavour jets and correlation gives direct access to the initial parton kinematics and can provide further...
