On 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 کاملDelta(1232) and Nucleon Spectral Functions in Hot Hadronic Matter
Modifications of ∆(1232) and nucleon spectral functions at finite temperature and baryon density are evaluated in terms of resonant scattering off thermal pions, as well as a renormalization of the vacuum ∆-width including vertex corrections. The interactions are based on effective Lagrangians of pions and baryon resonances, with underlying parameters (coupling constants and form factors) deter...
متن کامل0 Charge diffusion constant in hot and dense hadronic matter -
We evaluate charge diffusion constant of dense and hot hadronic matter based on the molecular dynamical method by using a hadronic collision generator which describes nuclear collisions at energies 10 GeV/A and satisfies detailed balance at low temperatures (T ≤ 200 MeV). For the hot and dense hadronic matter of the temperature range, T = 100 ∼ 200 MeV and baryon number density, nB = 0.16 fm ∼ ...
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 کاملDilepton production from resonance scattering in hot hadronic matter.
Dilepton production from resonance scattering in hot hadronic matter is studied. Including the widths of these resonances, which enhance the phase space for dilepton production, we find that the production rate is significantly increased if a resonance appears in the extended phase space. For the reaction π+ρ → l+ l, the finite ρ meson width extends the invariant mass below the ω-meson mass, so...
