Ultraviolet Flavor Transmission to T-Violating Neutrino Oscillation Observables in a Seesaw Framework with Sterile Mixing and Planck-Suppressed Corrections
Poulastya Kar, Bipin Singh Koranga, Vivek Nautiyal
We construct, numerically validate, and phenomenologically constrain a pipeline connecting a spontaneously CP-violating ultraviolet Type-I seesaw boundary condition to Planck-suppr…

Matter-Induced CPT Violation and Earth-Density Stratification Effects in Long-Baseline Neutrino Oscillation Experiments
Tia Pandit, Bipin Singh Koranga, Vivek Kumar Nautiyal
We present a unified analysis of two matter-potential systematics in long-baseline (LBL) neutrino oscillation experiments, treating matter-induced extrinsic CPT violation and Earth…

Matter Profile Mismodeling as the Origin of the CP CPT Degeneracy in Long-Baseline Neutrino Oscillation
Bipin Singh Koranga, Vivek Kumar Nautiyal
We demonstrate that approximating the Earth's density profile with a single path averaged value instead of the spatially resolved Preliminary Reference Earth Model PREM generates a…
