Microscopic formulation of the interacting boson-fermion model using the nuclear energy density functional

M. Homma, K. Nomura

Microscopic modeling of low-energy spectroscopy in medium-heavy and heavy odd- nuclei is an outstanding open problem in nuclear physics. We propose a novel spectra-generating co…

Microscopic determination of the interacting boson-fermion model Hamiltonian from the nuclear energy density functional

M. Homma, K. Nomura

A microscopic formulation of the interacting boson-fermion model for odd- nuclei is made using the nuclear energy density functional framework. Strength parameters for the boson…

Experimental Study of Rare Kaon Decays at J-PARC with KOTO and KOTO II

J. K. Ahn, E. Augustine, L. Bandiera +62

The rare kaon decay is extremely sensitive to new physics, because the contribution to this decay in the Standard Model (SM) is highly suppressed and known ver…

Sensitivity analysis of -decay half-life predictions for Ge, As, Zr and Mo nuclei within the mapped interacting boson model

M. Homma, K. Nomura

We analyze parameter sensitivities of the mapped interacting boson model (IBM) and boson-fermion-fermion model (IBFFM) in the description of -decay properties of the even-mass…

Parameter dependence of the -decay properties of neutron-rich Zr isotopes within the interacting boson model

M. Homma, K. Nomura

We investigate parameter dependence of the calculated -decay properties, as well as low-lying states for the neutron-rich Zr isotopes within the neutron-proton interacting boso…
