Thermal and baryon density modifications to the $\sigma$-boson propagator: A road to describe the transfer of vorticity to spin in a nuclear environment in relativistic heavy-ion collisions

Alejandro Ayala, José Jorge Medina-Serna, Isabel Domínguez +2

In the context of the description of how the vortical motion, produced in peripheral heavy-ion collisions, is transferred to the spin of hadrons, we compute the $\sigma$-meson propagato…
