A radius of a dense star on the color superconducting phase is investigated in an extended NJL type model with two flavors of quarks. Since the model is non-renormalizable, the results depend on the regularization procedure. Here we apply the dimensional regularization and evaluate the radius of a dense star. Evaluating the TOV equation, we show the relationship between mass and radius of the d...

Properties and temperature behavior 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.

The tunneling method for the Hawking radiation is revisited and applied to the D dimensional rotating case. Emphasis is given to covariance of results. Certain ambiguities afflicting the procedure are resolved. PACS numbers: 04.70.-s, 04.70.Dy
