27. Neutrino mass hierarchy from the discrete dark matter model

Omar Medina (IFIC (CSIC-Universitat de Valéncia))

Talk

We explore a possible explanation for the hierarchy in scale between the atmospheric and solar neutrino mass differences ($|\Delta m^2_{31}|$ and $\Delta m^2_{21}$)
through the presence of two distinct neutrino mass mechanisms from tree-level and one-loop-level contributions. We demonstrate
that the ingredients needed to explain this hierarchy are present in the minimal discrete dark matter...

71. Radiative Neutrino Mass with GeV Scale Majorana Dark Matter in Scotogenic Model

Avnish (Institute of Physics, Bhubaneswar, India.)

Talk

The experimental observations from the colliders
established the standard model (SM), is the most successful phenomenological
framework to explain the non-gravitational interactions of fundamental particles at
high energy. Non-zero neutrino mass and dark matter cast a shadow over its
success. This necessitates the extension of the SM. The most straightforward and
elegant extension of the SM to...

13. Hybrid scoto/seesaw: flavour and dark matter

Talk

I will present our recent work (arXiv:2204.13605 [hep-ph]) based on a hybrid type-II seesaw/scotogenic model supplemented with a discrete flavour symmetry where CP is dynamically generated by the vacuum. Namely, we analyse compatibility with low-energy neutrino observables, review the charged lepton flavour violation implications and study the scalar and fermionic dark matter phenomenology of...

70. Sterile neutrinos along the DUNE decay pipe

All

Talk

We analyse the sensitivity of the Deep Underground Neutrino Experiment (DUNE) to a sterile neutrino, combining information from both the Near Detector (ND) and the Far Detector (FD). DUNE's sterile exclusion reach is affected by taking into account the information on the neutrino production point, in contrast to assuming a point-like neutrino source. Visible differences remain after taking...

129. Latest results from the CUORE experiment

Dr Mattia Beretta (UC Berkeley)

Talk

The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for 0νββ decay that has been able to reach the one-tonne mass scale. The detector, located at the LNGS in Italy, consists of an array of 988 TeO2 crystals arranged in a compact cylindrical structure of 19 towers. CUORE began its first physics data run in 2017 at a base temperature of...

25. Influence of the Lorentz invariance violating interactions on discovery of CP violation and octant sensitivity at T2HK/T2HKK

Mr Supriya Pan (Physical Research Laboratory, Ahmedabad)

All

Talk

We study the effect of Lorentz invariance violating(LIV) parameters on the discovery of the non-zero CP phase ($\delta_{13}$) and the octant of 2-3 mixing angle ($\theta_{23}$) in the neutrino sector in the context of the proposed T2HK/T2HKK experiments. We consider the CPT violating case and taking one LIV parameter at a time, investigate to what extent the CP discovery and octant...
