When CPT Violation Hides in Plain Sight: How CP Measurements Are Compromised and How to Fix Them
Miaochen Jin, Gabriela Barenboim, Carlos A. Argüelles +2
The extraction of the leptonic charge-parity (CP)-violating phase from long-baseline neutrino oscillation experiments rests on the assumption of charge-parity-time (CP…

CHIC: Caley-Hamilton, Invariants and Constants for Neutrino Oscillation Probabilities and Gradients
Pablo Fernández-Menéndez
We use the Caley-Hamilton theorem to derive analytical solutions for the three-flavor neutrino propagation amplitude in a constant-density medium and their derivatives with respect…

Probing the general axion-nucleon interaction in water Cherenkov experiments
Mael Cavan-Piton, Diego Guadagnoli, Axel Iohner +2
We consider an axion flux on Earth consistent with emission from the Supernova explosion SN 1987A. Using Chiral Perturbation Theory augmented with an axion, we calculate the energy…
