Chemical relaxation time of pions in hot hadronic matter
We calculate characteristic time scales for chemical equilibration of pions in hot hadronic matter using an effective chiral Lagrangian. We find that inelastic processes involving the vector and axial vector mesons reduce the chemical equilibration time by a factor of ∼ 10 compared to the result previously calculated in chiral perturbation theory. For a temperature of T ∼ 150MeV we obtain a che...
متن کاملVirtual bremsstrahlung from pions and quarks in thermalized hadronic matter.
A soft photon approximation is used to calculate the rates of lepton pair production through virtual bremsstrahlung from both pions and quarks. Standard assumptions about the evolution of a nuclear system under collision allow pion and quark driven total production to be calculated. Comparisons are made with Dalitz decay of light mesons. These mechanisms are expected to be significant contribut...
متن کاملOn the Thermodynamics of Hot Hadronic Matter
The equation of state of hot hadronic matter is obtained, by taking into account the contribution of the massive states with the help of the resonance spectrum τ(m) ∼ m3 justified by the authors in previous papers. This equation of state is in agreement with that provided by the low-temperature expansion Bitnet: [email protected] Bitnet: [email protected]. On sabbatical leave from School o...
متن کاملSuppression of dilepton production in hot hadronic matter.
The pion electromagnetic form factor at finite temperature is studied using an effective chiral lagrangian that includes explicitly vector mesons. We find that in the time-like region around the rho meson resonance it decreases with increasing temperature and leads to a suppression of dilepton production from pion-pion annihilation in a hot hadronic matter. Effects on dilepton production in hig...
متن کاملSpectral Function of ρ in Dense and Hot Hadronic Matter
The spectral function of rho meson in hot/dense hadronic matter is calculated. Different from the pure temperature effect which changes the spectral function slightly, in the hadronic environment with high baryonic chemical potential and high temperature the spectral function becomes narrower and is shifted towards the low invariant mass region significantly. PACS: 14.40. Cs, 25.75. -q It is wi...
