Scalar σ meson at finite temperature in nonlocal quark model
- 1. Joint Institute for Nuclear Research, Dubna (Russian Federation)
- 2. Theory Division, GSI mbH, Darmstadt (Germany)
Description
Properties and temperature behaviour of π and σ bound states are studied in the framework of the nonlocal model with a separable interaction kernel based on the quark Dyson-Schwinger and the meson Bethe-Salpeter equations. Mπ(T), fπ(T), Mσ(T) and Γσ→ππ(T) are considered above and below the deconfinement and chiral restoration transitions
