Long-lived biνo at the LHC

We examine the detection prospects for a long-lived biνo, a pseudo-Dirac bino which is responsible for neutrino masses, at the LHC and at dedicated long-livedparticle detectors. The biνo arises in $U(1)_R$-symmetric …

Leptonic Sum Rules from Flavour Models with Modular Symmetries

Sum rules in the lepton sector provide an extremely valuable tool to classify flavour models in terms of relations between neutrino masses and mixing parameters testable in aplethora of experiments. In this manuscript we identify new …

A Statistical Analysis of the COHERENT Data and Applications to New Physics

The observation of coherent elastic neutrino nucleus scattering (CEνNS) by the COHERENT collaboration in 2017 has opened a new window to both test StandardModel predictions at relatively low energies and probe new physics scenarios. Our …

CP-Violating Neutrino Non-Standard Interactions in Long-Baseline-Accelerator Data

Neutrino oscillations in matter provide a unique probe of new physics. Leveraging the advent of neutrino appearance data from NOvA and T2K in recent years, we investigate the presence of CP-violating neutrino non-standard interactions …

Attractive scenario for light dark matter direct detection

Direct detection of light dark matter (DM), below the GeV scale, through electron recoil canbe efficient if DM has a velocity well above the virial value of $v\sim 10^{−3}$. We point out that if there is a long …

A testable hidden-sector model for Dark Matter and neutrino masses

We consider a minimal extension of the Standard Model with a hidden sectorcharged under a dark local U(1)′ gauge group, accounting simultaneously for light neutrinomasses and the observed Dark Matter relic abundance. The model contains two copiesof …

Bi𝝂o Phenomenology at the LHC

We study the LHC constraints on an R-symmetric SUSY model, where theneutrino masses are generated through higher dimensional operators involving the pseudo-Dirac bino, named biνo. We consider a particle spectrum where the squarks are heavier than …

Natural and Dynamical Neutrino Mass Mechanism at the LHC

We generalize the scalar triplet neutrino mass model, the type II seesaw. Requiring fine-tuning and arbitrarilysmall parameters to be absent leads to dynamical lepton number breaking at the electroweak scale and a richLHC phenomenology. A smoking gun …

IceCube bounds on sterile neutrinos above 10 eV

We study the capabilities of IceCube to search for sterile neutrinos with masses above 10 eV by analyzing its $\nu_\mu$ disappearance atmospheric neutrino sample. We find that IceCube is not only sensitive to the mixing of sterile …
