Neutral pion decay into in dense Skyrmion matter
Neutrinos and their means of production play an important role in cosmological and astrophysical phenomena [1]. In particular in this paper we shall be concerned with the weak emission of a neutrino-antineutrino pair from a neutral pion, 0 ! , which figures centrally in the pionpole mechanism [2,3] for the process ! 0 ! relevant to the neutrino emission process ! . The latter has been suggested...
متن کاملHard photon and neutral pion production in cold nuclear matter
The production of hard photons and neutral pions in 190 MeV proton induced reactions on C, Ca, Ni, and W targets has been for the first time concurrently studied. Angular distributions and energy spectra up to the kinematical limit are discussed and the production cross-sections are presented. From the target mass dependence of the cross-sections the propagation of pions through nuclear matter ...
متن کاملAntibaryon Production in Hot and Dense Nuclear Matter *
The production of antibaryons is calculated in a microscopic transport approach employing multiple meson fusion reactions according to detailed balance relations with respect to baryon-antibaryon annihilation. It is found that the abundancies of antiprotons as observed from peripheral to central collisions of P b + P b at the SPS and Au + Au at the AGS can approximately be described on the basi...
متن کاملThe antikaon nuclear potential in hot and dense matter
The antikaon optical potential in hot and dense nuclear matter is studied within the framework of a coupled-channel self-consistent calculation taking, as bare meson-baryon interaction, the meson-exchange potential of the Jülich group. Typical conditions found in heavy-ion collisions at GSI are explored. As in the case of zero temperature, the angular momentum components larger than L = 0 contr...
متن کاملThree Quark Clusters in Hot and Dense Nuclear Matter
We present a relativistic in-medium three-body equation to study correlations in hot and dense quark matter. The equation is solved for a zero-range force for parameters close to the phase transition of QCD.
