Autor: Hashida, J., Mukaigawa, S., Muta, T., Ohkura, K., Yamamoto, K.

Publikováno v: Phys.Rev. D61 (2000) 044015

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 dimensi

A Model of Curvature-Induced Phase Transitions in Inflationary Universe

Autor: Hashida, J., Mukaigawa, S., Muta, T., Ohkura, K., Yamamoto, K.

Publikováno v: Phys.Rev.D59:101302,1999

Chiral phase transitions driven by space-time curvature effects are investigated in de Sitter space in the supersymmetric Nambu-Jona-Lasinio model with soft supersymmetry breaking. The model is considered to be suitable for the analysis of possible p

Pattern of Chiral Symmetry Restoration at Finite Temperature in A Supersymmetric Composite Model

Autor: Hashida, J., Muta, T., Ohkura, K.

Publikováno v: Phys.Lett. B451 (1999) 343-348

The structure of chiral symmetry restorations at finite temperature is thoroughly investigated in the supersymmetric Nambu-Jona-Lasinio model with a soft supersymmetry breaking term. It is found that the broken chiral symmetry at vanishing temperatur

Report

Thermal Restoration of Chiral Symmetry in Supersymmetric Nambu-Jona-Lasinio Model with Soft SUSY Breaking

Autor: Hashida, J., Muta, T., Ohkura, K.

Publikováno v: Mod.Phys.Lett. A13 (1998) 1235-1240

The supersymmetric version of the Nambu-Jona-Lasinio model is investigated in connection with the chiral symmetry breaking induced by a soft SUSY breaking term. It is found that the broken chiral symmetry due to the soft breaking term is restored at
