Real and Virtual Propagation in Neutrino Oscillations
Kenji Nishiwaki, Kin-ya Oda, Juntaro Wada
We revisit flavor oscillations in vacuum in terms of the propagation time of intermediate states. In the limit of a long propagation time (or distance), degenerate intermediate sta…
Insights on the Scale of Leptogenesis from Neutrino Masses and Neutrinoless Double-Beta Decay
Alessandro Granelli, Koichi Hamaguchi, Maura E. Ramirez-Quezada +3
We revisit the thermal leptogenesis scenario in the type-I seesaw framework featuring three heavy Majorana neutrinos with a hierarchical mass spectrum. We focus on low energy obser…
Lorentz-covariant spinor wave packet
Kin-ya Oda, Juntaro Wada
We propose a novel formulation for a manifestly Lorentz-covariant spinor wave-packet basis. The traditional definition of the spinor wave packet is problematic due to its unavoidab…
Thermal Leptogenesis in the Minimal Gauged Model
Alessandro Granelli, Koichi Hamaguchi, Natsumi Nagata +2
We discuss the thermal leptogenesis mechanism within the minimal gauged U(1) model to explain the observed baryon asymmetry of the Universe (BAU). In such framework, th…
Revisiting Affleck-Dine Leptogenesis with light sleptons
Kazuki Enomoto, Koichi Hamaguchi, Kohei Kamada +1
We revisit the Affleck-Dine leptogenesis via the flat direction with a light slepton field. Although the light slepton field is favored in low-energy SUSY phenomenologies,…
Probing the - Gauge Boson at the MUonE Experiment
Kento Asai, Koichi Hamaguchi, Natsumi Nagata +2
We discuss the prospects of probing the gauge boson at the MUonE experiment. The gauge boson with a mass of MeV, which can explain t…
A complete set of Lorentz-invariant wave packets and modified uncertainty relation
Kin-ya Oda, Juntaro Wada
We define a set of fully Lorentz-invariant wave packets and show that it spans the corresponding one-particle Hilbert subspace, and hence the whole Fock space as well, with a manif…
