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…
Neutrino oscillations and scattering theory
Ilian Dobrev, Kirill Melnikov, Thomas Schwetz
We derive the neutrino oscillation probability in vacuum using scattering theory methods developed earlier in the context of collider physics. It is computed from Feynman diagrams…
Dynamics of metastable Standard Model particles from long-lived particle decays in the MeV primordial plasma
Kensuke Akita, Gideon Baur, Maksym Ovchynnikov +2
We investigate the cosmological impact of hypothetical unstable new physics particles that decay in the MeV-scale plasma of the Early Universe. Focusing on scenarios where the deca…
New physics decaying into metastable particles: impact on cosmic neutrinos
Kensuke Akita, Gideon Baur, Maksym Ovchynnikov +2
We investigate decays of hypothetical unstable new physics particles into metastable species such as muons, pions, or kaons in the Early Universe, when temperatures are in the MeV…
Not-so-inelastic Dark Matter
Giovani Dalla Valle Garcia, Felix Kahlhoefer, Maksym Ovchynnikov +1
Models of inelastic (or pseudo-Dirac) dark matter commonly assume an accidental symmetry between the left-handed and right-handed mass terms in order to suppress diagonal couplings…
Unitarity triangle test of the extra factor of two in particle oscillation phases
Samoil M. Bilenky, Walter Grimus, Thomas Schwetz
There are claims in the literature that in neutrino oscillations and oscillations of neutral kaons and B-mesons the oscillation phase differs from the standard one by a factor of t…
Elastic scattering of solar neutrinos with electromagnetic moments
W. Grimus, T. Schwetz
We consider the azimuthal asymmetry of the recoil electrons in elastic scattering of solar neutrinos, which can arise if neutrinos have electromagnetic moments and there is…
Elastic neutrino - electron scattering and potential effects of magnetic and electric dipole moments
W. Grimus, T. Schwetz
We consider elastic neutrino - electron scattering of solar neutrinos with magnetic moments and electric dipole moments, where the solar neutrino state at the scattering site is de…
