Description
Heavy quarks are produced in the early stages of heavy ion collisions due to their large mass, and subsequently traverse the entire QCD medium evolution.
The open heavy flavor hadron ratio provides profound insights into the heavy quark hadronization mechanisms . By comparing these ratios in different collision systems, which reveal the contribution of the coalescence mechanism in different medium.
In the lhcb experiment, fixed-target collisions cover an unexplored energy range that is above previous fixed-target experiments, but below the top RHIC energy for AA collisions.
In pPb collisions, heavy quarks are crucial to study cold nuclear matter effects, which include the modification of nuclear parton distribution functions, energy loss in the nucleus, and other effects, providing a baseline for interpreting PbPb measurements.
