High energy photons may be produced in nuclear reactions by several mechanisms, including bremsstrahlung from the potential field or from nucleon-nucleon collisions. Using infinite and semi-infinite nuclear matter approximations, we obtain simple expressions for the rates. Nucleon-nucleon collisions provide the more important mechanism for both proton-induced and heavy-ion induced reactions, except for the highest energy photons. The photon cross section calculated with a zero range np…

Phase space model of hard-photon production in heavy-ion collisions
SummaryWe propose a semi-classical model to study the characteristics of the observed hard-photon production in heavy-ion collisions. For this we divide the nucleons in two categories on a
Hard Photons and Subthreshold Mesons from Nucleus-Nucleus Collisions
The study of nucleus-nucleus collisions at an energy high enough to allow for an appreciable nuclear overlap is the only experimental means to obtain information about the properties of nuclear

TLDR
It may be possible to infer the pion dispersion relation in hot and dense nuclear matter by measuring the invariant mass distribution of back-to-back electrons and positrons in the center of mass frame in high energy nucleus-nucleus collisions.
Inclusive γ and π 0 cross sections in heavy-ion reactions
Perturbation theory in a time-dependent basis is used to derive formal expressions for pion and gamma emission in heavy-ion reactions. The structure of the theory motivates an external mean-field
Emission of protons in the extreme kinematical region from nuclear cooperation in heavy-ion collisions
The authors investigate the emission of energetic protons at backward angles in intermediate-energy heavy-ion collisions within the cooperative model developed earlier. Using the same ingredients as
Probing nuclear symmetry energy at high densities using pion, kaon, eta and photon productions in heavy-ion collisions
Abstract.The high-density behavior of nuclear symmetry energy is among the most uncertain properties of dense neutron-rich matter. Its accurate determination has significant ramifications in
