Displaced vertex signatures of a pseudo-Goldstone sterile neutrino
Journal of High Energy Physics, 2021 Low-scale models of neutrino mass generation often feature sterile neutrinos with masses in the GeV-TeV range, which can be produced at colliders through their mixing with the Standard Model neutrinos.

Scotogenic S3 symmetric generation of realistic neutrino mixing [PDF]
Physical Review D, 2019 Realistic neutrino mixing is achieved at one-loop level radiatively using $S3\times Z_2$ symmetry. The model comprises of two right-handed neutrinos, maximally mixed to produce the structure of the left-handed Majorana neutrino mass matrix characterized ...

Neutrino mixing from finite modular groups [PDF]
Physical Review D, 2018 We study the lepton flavor models, whose flavor symmetries are finite subgroups of the modular group such as $S_3$ and $A_4$. In our models, couplings are also nontrivial representations of these groups and modular functions of the modulus.

Modular A4 invariance and neutrino mixing [PDF]
Journal of High Energy Physics, 2018 We study the phenomenological implications of the modular symmetry Γ(3) ≃ A4 of lepton flavors facing recent experimental data of neutrino oscillations.

Improved sensitivities of ESSνSB from a two-detector fit
Journal of High Energy Physics, 2023 We discuss the improvement of the sensitivity of ESSνSB to the discovery of CP violation and to new neutrino physics which can be obtained with a two-detector fit of the data of the near and far detectors. In particular, we consider neutrino non-standard

Stochastic neutrino mixing mechanism [PDF]
Physical Review D, 2013 We propose a mechanism which provides an explanation of the Gallium and antineutrino reactor anomalies. Differently from original Pontecorvo's hypothesis, this mechanism is based on the phenomenological assumption in which the admixture of neutrino mass eigenstates in the moments of neutrino creation and detection can assume different configurations ...

Displaced vertices as probes of sterile neutrino mixing at the LHC [PDF]
Physical Review D, 2018 We investigate the reach at the LHC to probe light sterile neutrinos with displaced vertices. We focus on sterile neutrinos $N$ with masses $m_{N} \sim $ (5-30) GeV, that are produced in rare decays of the Standard Model gauge bosons and decay inside the

Deviations in tribimaximal mixing from sterile neutrino sector
Nuclear Physics B, 2016 We explore the possibility of generating a non-zero Ue3 element of the neutrino mixing matrix from tribimaximal neutrino mixing by adding a light sterile neutrino to the active neutrinos.

Measurement of the Neutrino Mixing Angle θ_{23} in NOvA. [PDF]
Physical Review Letters, 2017 This Letter reports new results on muon neutrino disappearance from NOvA, using a 14 kton detector equivalent exposure of 6.05×10^{20} protons on target from the NuMI beam at the Fermi National Accelerator Laboratory.

Neutrino Oscillations: from Standard and Non-standard Viewpoints [PDF]
, 2011 In the standard model of neutrino oscillations, the neutrino flavor states are mixtures of mass-eigenstates, and the phenomena are well described by the neutrino mixing matrix, i.e., the PMNS matrix. I review the recent progress on parametrization of the
