CPT Violation in Neutrino Oscillations with Quantum-Gravitational Decoherence — •Erika Rani1,2, Heinrich Päs1, and Dominik Hellmann1 — 1TU Dortmund, Lehrstuhl für Theoretische Physik III — 2UIN Maulana Malik Ibrahim Malang, Indonesia
Quantum gravity effects can lead to the violation of fundamental symmetries, including global symmetries such as flavor, baryon and lepton number and discrete symmetries such as CPT. In this talk, we investigate CPT violation in neutrino oscillations in the context of quantum-gravitational decoherence. By employing the Ellis, Hagelin, Nanopoulos, and Srednicki (EHNS) formalism we study a two-flavor scenario and discuss the size of the effect in different parametrizations.
