Dissipative corrections to the particle momentum spectrum of a decoupling fluid
Francesco Becattini, Daniele Roselli, Xin-Li Sheng
We present an \emph{ab initio} calculation within quantum statistical field theory and linear response theory, of the dissipative correction to the momentum spectrum of scalar part…

An improved formula for Wigner function and spin polarization in a decoupling relativistic fluid at local thermodynamic equilibrium
Xin-Li Sheng, Francesco Becattini, Daniele Roselli
We present an upgraded formula for Wigner function and spin polarization of fermions emitted by a relativistic fluid at local thermodynamic equilibrium at the decoupling which impr…
