Chromomagnetic Catalysis of Color Superconductivity in a (2+1)-dimensional NJL Model
نویسنده
چکیده
The influence of a constant uniform external chromomagnetic field H on the formation of color superconductivity has been investigated. The consideration was performed in the framework of a (2+1)-dimensional Nambu–Jona-Lasinio model with two different four-fermionic structures responsible for < q̄q > and diquark < qq > condensates. In particular, it was shown that there exists a critical value Hc of the external chromomagnetic field such that at H > Hc a nonvanishing diquark condensate is dynamically created (the so-called chromomagnetic catalysis effect of color superconductivity). Moreover, external chromomagnetic fields may in some cases enhance the diquark condensate of color superconductivity. PACS: 12.38.-t, 11.15.Ex, 97.60.Jd Typeset using REVTEX

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...

متن کاملThe Influence of an External Chromomagnetic Field on Color Superconductivity Typeset Using Revt E X 1
We study the competition of quark-antiquark and diquark condensates under the influence of an external chromomagnetic field modelling the gluon condensate and in dependence on the chemical potential and temperature. As our results indicate, an external chromomagnetic field might produce remarkable qualitative changes in the picture of the color superconducting phase formation. PACS: 12.38.-t, 1...
متن کاملPhase diagrams of the three-flavor NJL model with color superconductivity and pseudoscalar condensation
We present results of the calculation of phase diagrams of the three-flavor NJL model as a function of temperature and different quark chemical potentials. These phase diagrams are an extension of earlier calculations in the literature in which either only the possibility of color superconductivity or the possibility of pseudoscalar condensation was investigated. This study takes into account b...
