Probing T and CP Violation at DUNE and T2HK
Sabya Sachi Chatterjee, Sudhanwa Patra, Thomas Schwetz +1
We study the sensitivity of the DUNE and T2HK long-baseline experiments to time reversal (T) violation in neutrino oscillations. Rather than the conventional approach of exchanging…
Oscillating Neutrinos vs. Oscillating Scalars: Constraining Scalar Dark Matter-Induced Neutrino Mass
Kierthika Chathirathas, Sabya Sachi Chatterjee, Thomas Schwetz
We consider the hypothesis that neutrino masses are generated by a coupling to an ultra-light (pseudo-)scalar field, which provides the dark matter in the universe. This leads to t…
Effective Matter Flavor Conversion Mediated by Pseudo-Sterile States as the Possible Origin of Neutrino Oscillation Anomalies
Sabya Sachi Chatterjee, Antonio Palazzo
Neutrino oscillation experiments present anomalous results across a vast range of baselines and energies. Here we show that a 3+1 scenario in which sterile neutrinos feel a novel m…
T versus CP effects in DUNE and T2HK
Sabya Sachi Chatterjee, Sudhanwa Patra, Thomas Schwetz +1
Time reversal (T) symmetry violations in neutrino oscillations imply the presence of an -odd component in the transition probability at fixed neutrino energy, with denoting…
Testing the heavy decaying sterile neutrino hypothesis at the DUNE near detector
Sabya Sachi Chatterjee, Stéphane Lavignac, O. G. Miranda
One of the most convincing explanations of the LSND and MiniBooNE anomalies relies on a heavy, mostly sterile neutrino with a small muon neutrino component, which decays to an elec…
Model-independent search for T violation with T2HK and DUNE
Sabya Sachi Chatterjee, Sudhanwa Patra, Thomas Schwetz +1
We consider the time reversal (T) transformation in neutrino oscillations in a model-independent way by comparing the observed transition probabilities at two different baselines a…
