    Light sterile neutrino and leptogenesis

    We studied models of leptogenesis where three right-handed Majorana neutrinos are involved and the minimal-extended seesaw mechanism including an additional singlet field produces four light neutrinos. This st...

    Seesaw scale and CP phases in a minimal model of leptogenesis

    The seesaw mechanism to derive the light masses of left-handed neutrinos using heavy masses of right-handed neutrinos gives rise to a connection between low-energy measurables and Grand Unified Theory (GUT)-sc...

    Comparison of fast neutron rates for the NEOS experiment

    The fast neutron rates are compared at the site of the NEOS (Neutrino Experiment Oscillation Short baseline) experiment, a short-baseline neutrino experiment located in a tendon gallery of a commercial nuclear...

    Development and mass production of a mixture of LAB- and DIN-based gadolinium-loaded liquid scintillator for the NEOS short-baseline neutrino experiment

    A new experiment, called the NEutrino Oscillation at Short baseline (NEOS), is proposed on the site of Hanbit Reactors at Yonggwang, South Korea, to investigate a reactor antineutrino anomaly. The homogeneous ...

    Ansatz of leptonic mixing: The alliance of bi-maximal mixing with a single-angle rotation

    We introduce an ansatz of the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) matrix that consists of specific types of transformations. Bi-maximal mixing is taken for the neutrino masses while a single-angle rotation ...

    Non-vanishing U e3 under S 3 symmetry

    This work proposes two models of neutrino masses that predict non-zero θ 13 under the non-Abelian discrete flavor symmetry ...
