Spin kinetic theory with a nonlocal relaxation time approximation
Nora Weickgenannt, Jean-Paul Blaizot
We present a novel relaxation time approximation for kinetic theory with spin which takes into account the nonlocality of particle collisions. In particular, it models the property…
Phenomenology of isospin-symmetry breaking with vector mesons
Péter Kovács, György Wolf, Nora Weickgenannt +1
We study the effect of isospin-symmetry breaking in the framework of the extended Linear Sigma Model (eLSM) in vacuum. In this model, several particles mix with each other at tree…
Polarization dynamics from moment equations
Nora Weickgenannt, Jean-Paul Blaizot
We derive an expression for the local transverse polarization of a boost-invariant expanding system of massive particles, which involves a set of dynamical spin moments. Starting f…
Chiral hydrodynamics of expanding systems
Nora Weickgenannt, Jean-Paul Blaizot
We obtain equations of motion for the boost-invariant expansion of a system of chiral particles. Our analysis is based on the Boltzmann equation for left- and right-handed massless…
Generating spin polarization from vorticity through nonlocal collisions
Nora Weickgenannt, Enrico Speranza, Xin-li Sheng +2
We derive the collision term in the Boltzmann equation using the equation of motion for the Wigner function of massive spin-1/2 particles. To next-to-lowest order in it con…
Wigner function and kinetic theory for massive spin-1/2 particles
Nora Weickgenannt, Xin-li Sheng, Enrico Speranza +2
We calculate the Wigner function for massive spin-1/2 particles in an inhomogeneous electromagnetic field to leading order in the Planck constant . Going beyond leading orde…
Kinetic theory for massive spin-1/2 particles from the Wigner-function formalism
Nora Weickgenannt, Xin-li Sheng, Enrico Speranza +2
We calculate the Wigner function for massive spin-1/2 particles in an inhomogeneous electromagnetic field to leading order in the Planck constant . Going beyond leading orde…
