摘要
Resonances with very short lifetimes can be used to probe the rescattering and regeneration processes in the hadronic phase of the system produced after a high-energy collisions. These processes are studied by measuring resonance yields as a function of the system size and collision energy and comparing them to model calculations with and without the hadronic cascades. We present measurements of transverse momentum spectra, integrated yields (dN/dy), mean transverse momenta (< p(T)>), and angular distributions for light flavor hadronic resonances in pp, p-Pb, Xe-Xe, and Pb-Pb collisions at LHC energies. The < p(T)> of resonances as a function of event multiplicity in central Pb-Pb collisions follow the same mass ordering as for other hadrons, expected from the hydrodynamic expansion of the system. At high p(T) (> 8 GeV/c), nuclear modification factor (R-AA) of light flavor hadrons in central Pb-Pb collisions shows strong suppression, whereas the nuclear modification factor in p-Pb collisions, known as R-pPb is consistent with unity. This parton energy loss effect is independent of the particle species. Further, in non-central heavy-ion collisions, the vector mesons can be polarized due to spin-orbital-angular-momentum interaction or hadronization from polarized quarks due to their significant initial angular momentum. Recent measurements of spin alignment for K-0 and phi mesons produced at midrapidity in pp and Pb-Pb collisions are discussed.
