Vacuum angle theta in a strongly interacting hidden sector and its effect
Shinji Maedan
Introducing a vacuum angle in a strongly interacting hidden sector like QCD, we study how affects physical quantities in a scale invariant extension of the standard mod…
Influence of EOS on compact star made of hidden sector nucleons
Shinji Maedan
We study compact star made of degenerate hidden sector nucleons which will be a candidate for cold dark matter. A hidden sector like QCD is considered, and as the low energy effect…
Predicted value of -decay effective Majorana mass with error of lightest neutrino mass
Shinji Maedan
Assuming that the lightest neutrino mass is measured, we study the influence of error of the measured on the uncertainty of the predicted value of the neutrinoless…
Analytically expressed constraint on two Majorana phases in neutrinoless double beta decay
Shinji Maedan
We assume that neutrinoless double beta decay is caused by the exchange of three light Majorana neutrinos. Under this assumption, we obtain, by the method of perturbation, the equa…
Influence of current mass on the spatially inhomogeneous chiral condensate
Shinji Maedan
It is known that, in the chiral limit, spatially inhomogeneous chiral condensate occurs in the Nambu-Jona-Lasinio (NJL) model at finite density within a mean-field approximation. W…
Spin polarization and chiral symmetry breaking at finite density
Shinji Maedan
We investigate the possibility of the spin polarization of quark matter at zero temperature and moderate baryon density.The Nambu-Jona-Lasinio (NJL) model including interactions in…
