Majorana CP Violation Insights from Decaying Neutrinos
Sabila Parveen, Soumya Bonthu, Newton Nath +2
It is well-known that within the standard three flavor neutrino oscillation formalism, the Majorana phases appearing in the neutrino mixing matrix cannot have any effect on neutrin…

Enhanced violation of Leggett-Garg Inequality in three flavour neutrino oscillations via non-standard interactions
Sheeba Shafaq, Poonam Mehta
Neutrino oscillations occur due to non-zero masses and mixings and most importantly they are believed to maintain quantum coherence even over astrophysical length scales. In the pr…
Impact of high energy beam tunes on the sensitivities to the standard unknowns at DUNE
Jogesh Rout, Samiran Roy, Mehedi Masud +2
Even though neutrino oscillations have been conclusively established, there are a few unanswered questions pertaining to leptonic Charge Parity violation (CPV), mass hierarchy (MH)…
