Resonant decay of parity odd bubbles in hot hadronic matter
نویسنده
چکیده
We investigate the decay of metastable states with broken CP-symmetry which have recently been proposed by Kharzeev, Pisarski and Tytgat to form in hot hadronic matter. We consider the efficiency of the amplification of the η′-field via parametric resonance, taking the backreaction into account. For times of the order t ≈ 10fm, we find a particle density of about 0.7 /fm and a correlation length of ξmax ≈ 2.5fm. The corresponding momentum spectra show a non-thermal behaviour.

Parity Odd Bubbles in Hot Qcd
We consider the topological susceptibility for an SU(N) gauge theory in the limit of a large number of colors, N → ∞. At nonzero temperature, the behavior of the topological susceptibility depends upon the order of the deconfining phase transition. The most interesting possibility is if the deconfining transition, at T = Td, is of second order. Then we argue that Witten’s relation implies that ...
متن کاملEffective Hamiltonian of Electroweak Penguin for Hadronic b Quark Decays
In this research we work with the effective Hamiltonian and the quark model. We investigate the decay rates of matter-antimatter of quark. We describe the effective Hamiltonian theory and apply this theory to the calculation of current-current ( ), QCD penguin ( ), magnetic dipole ( ) and electroweak penguin ( ) decay rates. The gluonic penguin structure of hadronic decays is studied thro...

This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...
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 کاملThe ∆(1232) at RHIC
We investigate properties of the ∆(1232) and nucleon spectral functions at finite temperature and baryon density within a hadronic model. The medium modifications of the ∆ consist of a renormalization of its pion-nucleon cloud and resonant π∆ scattering. Underlying coupling constants and form factors are determined by the elastic πN scattering phase shift in the isobar channel, as well as empir...
