Curvature-induced phase transitions in the inflationary universe-Supersymmetric Nambu-Jona-Lasinio Model in de Sitter spacetime -

Abstract

The phase structure associated with the chiral symmetry is thoroughly investigated in de Sitter spacetime in the supersymmetric Nambu-Jona-Lasinio model with supersymmetry breaking terms. The argument is given in the three and four space-time dimensions in the leading order of the 1/N expansion and it is shown that the phase characteristics of the chiral… (More)
