متن نمونه
The mass and decay constants of rho(2), omega(2) and a missing member in the 2(--) nonet along with their first excited states are analyzed by the Thermal QCD sum rules approach, including QCD condensates up to dimension five. Mass and decay constant values of these mesons are stable from T = 0 up to T congruent to 120 MeV. However, after this threshold point, our numerical analyses indicates that they begin to diminish with increasing temperature. When we compare the hadronic parameters with their vacuum values, masses of these mesons and their first excited states decrease between (1-13%) from the PDG data and (10-26%) for the decay constants. However they diminish in the interval of (9-26%) and (2-34%) respectively with regards to Regge Trajectory Model data. We expect our numerical results will be confirmed by future heavy-ion collision experiments.
