Neutrinos I
- Peter Denton (Niels Bohr International Academy)
Neutrinos are copiously produced at particle colliders, but no collider neutrino has ever been detected. FASERv, a recently approved subdetector of FASER, is designed to detect such collider neutrinos for the first time and study their properties. In this talk, I will show that the small and inexpensive emulsion detector will be able to detect thousands of neutrino interactions with TeV...
A gauged $U(1)_X$ extension of the Standard Model is a simple and consistent framework to naturally incorporate three right-handed neutrinos (RHNs) for generating the observed light neutrino masses and mixing by the type-I seesaw mechanism. We examine the collider testability of the $U(1)_X$ model, both in its minimal form with the conventional charges, as well as with an alternative charge...
We study the constraints on the General Neutrino Interactions (GNI) based on the framework of the Standard Model Effective Field Theory extended with right-handed neutrinos N (SMNEFT) from low-energy probes (neutrino scattering, nuclear beta decay, and meson decay), and high energy electron-proton and proton-proton colliders. We compute the one-loop anomalous dimensions of the low-energy...
Physics beyond the standard model may induce significant deviations in the couplings involving neutrinos generally referred to as Non-Standard neutrino Interactions (NSI). We present a complementarity study between LHC and oscillation experiments to probe NSIs. We perform the analyses in a simplified model and an illustrative ultraviolet completion. The present and high-luminosity LHC...
Non-standard interactions (NSI) of neutrinos with matter mediated by a scalar field would induce medium-dependent neutrino masses which can modify oscillation probabilities. Generating observable effects requires an ultra-light scalar mediator. I'll talk about general results for the scalar NSI using techniques of quantum field theory at finite density and temperature, including the long-range...
Neutrino-electron scattering provides a clean tool constraining the neutrino flux at accelerator-based neutrino facilities and requires precise theoretical predictions. We determine the effective theory of neutrino-electron and neutrino-quark scattering and provide the most precise up-to-date prediction for neutrino-electron scattering cross sections quantifying errors for the first time to be...
It is widely accepted that the standard model is not a complete theory and there is new physics to be found. One example is the experimental finding that neutrinos oscillate between flavors which is only possible if the neutrinos have non-zero mass. The flavor mixing of massive neutrinos is described by the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) matrix leading to charged lepton flavor...
