The finite-temperature equation of state (EOS) is analyzed within an effective Lagrangian framework, where the dilaton field encodes the breaking of scale symmetry in QCD. In the pure gauge $SU(3)_c$ sector, the gluon condensate dynamics are described through a dilaton Lagrangian: at low temperature the condensate is dominated by the dilaton, while above the critical temperature it evaporates...
The ab initio calculation of optical potentials, grounded in the microscopic Hamiltonian, and the consistent evaluation of cross sections requires accounting for high-order virtual excitations, whose number grows factorially with perturbative order. This limitation has long hindered ab initio calculations of scattering observables, which instead rely on phenomenological models of optical...
I will show how a unified picture of HF-hadron production in high-energy hadronic collisions can be developed under the assumption that both in pp and in AA events a small/large drop of hot deconfined matter is formed, affecting the propagation and eventual hadronization of heavy quarks. Our calculations include a transport setup (POWLANG) interfaced with an hadronization model based on a...
