Propagation of Semiclassical Wave Front Sets for Non-Self-Adjoint Matrix-Valued Pseudo-Differential Operators
Yuta Kawamura
We study the semiclassical wave front set of vector-valued microlocal solutions to the pseudo-differential system with a non-Hermitian matrix-valued symbol. The main result establi…
Determination of Majorana type-phases from the time evolution of lepton numbers
Nicholas J. Benoit, Yuta Kawamura, Saki Hamada +3
We have investigated an approach for determining the Majorana type-phases using the time evolution of lepton family numbers. We show how the second-order time derivative of the exp…
Effective theory for universal seesaw model and FCNC
Takuya Morozumi, Apriadi Salim Adam, Yuta Kawamura +3
We study the quark sector of the universal seesaw model with SU(2) SU(2) .The model incorporates the seesaw mechanism with the vector-like quarks (V…
Time evolution of the lepton number of Majorana neutrinos in the Schrödinger picture versus Heisenberg picture
Nicholas J. Benoit, Yuta Kawamura, Takuya Morozumi
In this paper, we study the time evolution of the expectation value of Majorana neutrino with the Schrödinger picture.The operators with the definite lepton number and operators wi…
A model with light and heavy scalars in view of the effective theory
Apriadi Salim Adam, Yuta Kawamura, Takuya Morozumi
The low energy effective potential for the model with a light scalar and a heavy scalar is derived. We perform the path integration for both heavy and light scalars and derive the…
Spacetime evolution of lepton number densities and wave packet-like effects for neutrino flavor and chiral oscillations in quantum field theory
Apriadi Salim Adam, Nicholas J. Benoit, Yuta Kawamura +4
We present a formulation of lepton family numbers, based on quantum field theory, for neutrino oscillation phenomenology that can be applied to nonrelativistic and relativistic ene…
Lepton family numbers and non-relativistic Majorana neutrinos
Apriadi Salim Adam, Nicholas J. Benoit, Yuta Kawamura +5
In this talk, we have reviewed the recent development on the time evolution of lepton family number carried by Majorana neutrinos \cite{Adam:2021qiq}. This article focuses on the s…
Time Evolution of Lepton Number Carried by Majorana Neutrinos
Apriadi Salim Adam, Nicholas J. Benoit, Yuta Kawamura +5
We revisit the time evolution of the lepton family number for a SU(2) doublet consisting of a neutrino and a charged lepton. The lepton family number is defined through the weak ba…
Lepton number violation in a unified framework
Yuta Kawamura, Yamato Matsuo, Takuya Morozumi +4
We study the time evolution of lepton family number for neutrino which forms SU(2) doublet with charged lepton. The lepton family number is defined through a weak basis of SU(2) do…
