Parallel Session - Heavy Flavor I
- Roberta Arnaldi (Universita e INFN Torino (IT))
Charm quarks are a powerful probe of the Quark-Gluon Plasma (QGP) formed in
high- energy heavy-ion collisions. Produced in hard scattering processes on a
timescale shorter than the QGP formation time, they experience the whole evolution
of the medium interacting with its constituents. The measurements of charm-hadron
production allows testing the mechanisms of in-medium parton energy...
The enhancements of D_s/D^0 and Lambda_c/D^0 ratios in heavy-ion collisions as recently measured at RHIC and the LHC have posed formidable challenges for
theoretical models. We address these puzzles by developing a theoretically
controlled hadronization framework of heavy quarks that conserves 4-momentum and
recovers thermal and chemical equilibrium limits [1]. In particular, we implement...
Heavy quarks are initially produced in nuclear collisions and the number is conserved during the evolution of the system. We establish a sequential coalescence model with charm conservation and apply it to charmed hadron production at RHIC and LHC energies. The charm conservation enhances the earlier formed hadrons and reduces the later formed ones, which leads to a $D_s/D^0$ enhancement and a...
In hadronic collisions, beauty quarks are produced in hard scattering processes with large momentum transfer.Their production provides a very important test of perturbative QCD calculations in pp collisions. In heavy-ion collisions, the measurement of beauty hadron production is a unique tool to investigate the properties of the Quark-Gluon Plasma. In particular, beauty quarks, being four...
Heavy flavor physics in high-energy heavy-ion collisions is a promising and active area to study the `` jet quenching " effects both at the RHIC and the LHC. The recent reported $D^0$ meson radial profiles in jets measured by CMS collaboration provide new experimental constraints on the mechanisms of heavy flavor production in proton-proton collisions and give new insights into the in-medium...
