Abstract: A bstractWe study the minimal seesaw model, where two right-handed Majorana neutrinos are introduced, focusing on the CP violating phase. In addition, we take the trimaximal mixing pattern for the neutrino flavor where the charged… read more here.

DOI: 10.1103/physrevd.100.075013
Abstract: We propose an inverse seesaw model based on hidden global symmetry $U(1)_H$ in which we realize tiny neutrino masses with rather natural manner taking into account relevant experimental bounds. The small Majorana mass for inverse… read more here.

DOI: 10.1103/physrevd.100.115011
Abstract: We propose a linear seesaw model with a hidden gauge symmetry $SU(2)_H \times U(1)_X$ where two types of standard model singlet fermions in realizing a linear seesaw mechanism are unified into $SU(2)_H$ doublet. Then we… read more here.

DOI: 10.1103/physrevd.103.076005
Abstract: In this paper, we investigate the double covering of modular $\Gamma^{}_5 \simeq A^{}_5$ group and derive all the modular forms of weight one for the first time. The modular forms of higher weights are also… read more here.

DOI: 10.1103/physrevd.105.035011
Abstract: In the seesaw framework, in the basis of MR being diagonal, we explore the simplified textures of MD that can naturally yield the trimaximal neutrino mixings and their consequences for the neutrino parameters and leptogenesis.… read more here.

DOI: 10.1103/physrevd.99.055027
Abstract: We propose a new kind of inverse seesaw model without any additional symmetries. Instead of the symmetries, we introduce several fermions and bosons with higher $SU(2)_L$ representations. After formulating the Higgs sector and neutrino sector,… read more here.
