The limitations of the Standard Model in explaining neutrino masses and neutrino mixing leads
to the exploration of frameworks beyond the Standard Model (BSM). The possibility of neutrinos
interacting with fermions via a scalar mediator is one of the interesting prospects. The study of
neutrino non-standard interactions (NSI) is a well-motivated phenomenological scenario to explore
new...
We study the possibility of measuring T (time reversal) violation in a future
long-baseline neutrino oscillation experiment. By assuming a neutrino factory as a
staging scenario of a muon collider at the J-PARC site, we find that the \nu_e → \nu_\mu oscillation probabilities can be measured with a good accuracy at the Hyper-
Kamiokande detector. By comparing with the probability of the...
Upcoming neutrino experiments will soon search for new neutrino interactions more thoroughly than ever before, boosting the prospects of extending the Standard Model. In anticipation of this, we forecast the capability of two of the leading long-baseline neutrino oscillation experiments, DUNE and T2HK, to look for new flavor-dependent neutrino interactions with electrons, protons, and...
Discovering new neutrino interactions would represent evidence of physics beyond the Standard Model. We focus on new flavor-dependent long-range neutrino interactions mediated by ultra-light mediators, with masses below $10^{-10}$~eV, introduced by new lepton-number gauge symmetries $L_e-L_\mu$, $L_e-L_\tau$, and $L_\mu-L_\tau$. Because the interaction range is ultra-long, nearby and distant...
We investigate the effect on neutrino oscillations generated by new physics interactions between neutrinos and matter. Specifically, we focus on scalar-mediated nonstandard interactions (NSI) whose impact fundamentally differs from that of vector-mediated NSI. Scalar NSI contribute as corrections to the neutrino mass matrix rather than the matter potential and thereby predict distinct...
