Off-shell pions in the BUU transport theory
Due to the large resonance πN scattering cross section a pion with momentum ∼ 0.3 GeV/c acquires a width in nuclear matter. The pion spectral function in nuclear matter is, therefore, different from the vacuum one. The present work is the first attempt to include the pion spectral function into the BUU transport theory. We have calculated the pion polarization function Πc(k) in isospin symmetri...
متن کاملDirect simulation Monte Carlo method for the Uehling-Uhlenbeck-Boltzmann equation.
In this paper we describe a direct simulation Monte Carlo algorithm for the Uehling-Uhlenbeck-Boltzmann equation in terms of Markov processes. This provides a unifying framework for both the classical Boltzmann case as well as the Fermi-Dirac and Bose-Einstein cases. We establish the foundation of the algorithm by demonstrating its link to the kinetic equation. By numerical experiments we study...
متن کاملOff-shell electromagnetic form factors of pions and kaons in chiral perturbation theory.
The off–shell electromagnetic vertex of a (pseudo–) scalar particle contains, in general, two form factors F and G which depend, in addition to the squared momentum transfer, on the invariant masses associated with the initial and final legs of the vertex. Chiral perturbation theory to one loop is used to calculate the off–shell form factors of pions and kaons. The formalism of Gasser and Leutw...
متن کاملRelativistic Vlasov-Uehling-Uhlenbeck equation for nucleus-nucleus collisions.
The Vlasov-Uehling-Uhlenbeck (VUU) model introduced by Bertsch et al. ' for heavy-ion collisions has been used extensively in the study of the dynamics of heavyion collisions, ' particle productions from such reactions, ' and the properties of nuclear matter under extreme conditions. ' Although this model is carried out with the relativistic kinematics, it ignores the explicit exchange of meson...
متن کاملOn the Fundamental Solution of a Linearized Uehling-uhlenbeck Equation
In this paper we describe the fundamental solution of the equation that is obtained linearizing the Uehling-Uhlenbeck equation around the steady state of Kolmogorov type f(k) = k−7/6. Detailed estimates on its asymptotics are obtained.
