Oral presentation in parallel session
I present the new approach of flavor symmetry, which is based on modular invariance. I discuss the phenomenological implications of the modular symmetry $\Gamma(3) \simeq A_4$ of lepton flavors facing recent experimental data of neutrino oscillations.
The mass matrices of neutrinos and charged leptons are essentially given by fixing the expectation value of modulus $\tau$, which is the only...

Oral presentation in parallel session
The neutrino oscillation can probe not only the neutrino mass matrix but also the neutrino interactions. In other words, it provides two possible ways of determing the new physics beyond the SM. A commonly discussed example is the vector non-standard interactions (NSI) by vector mediators other than W & Z. We introduce another two possibilities of the scalar & dark NSIs. The scalar NSI is an...

Oral presentation in parallel session
Neutrino electron scattering is a purely leptonic fundamental interaction and therefore provides an important channel to test Standard Model especially at the low energy-momentum transfer regime. Constraints on neutrino non-standard interactions (NSI) couplings depending on model independent approaches, which are described by a four-Fermi point like interaction, are derived. The upper limits...

Oral presentation in parallel session
We continue our discussions [1-3] of neutrino electromagnetic properties and give a short introduction to the derivation of the general structure of the electromagnetic form factors of Dirac and Majorana neutrinos. Then we consider experimental constraints on neutrino magnetic and electric dipole moments, electric millicharge, charge radii and anapole moments from the terrestrial laboratory...

Oral presentation in parallel session
If there was a coupling between neutrinos and Dark Matter, then there could be an induced modulation of the neutrino-mixing spectrum analogous to the one produced by the MSW effect. The possible results of such a modulation have previously been investigated for the case where coherent effects cannot be isolated and the resulting pattern is de-coherent. This presentation is on an...
