Current and future neutrino experiments aim to precisely determine unknown oscillation parameters like the leptonic CP phase and mass hierarchy. Lorentz invariance violation (LIV) may introduce new physics affecting these measurements. This study investigates the impact of non-isotropic CPT-violating ( \(a^{X}_{\alpha \beta }\) ) and CPT-conserving ( \(c^{XY}_{\alpha \beta }\) ) LIV parameters on sensitivity of DUNE to mass hierarchy (MH) and CP violation. We find MH sensitivity remains robust except for \(c^{XY}_{\mu \tau }\) , which reduces sensitivity but stays above \(5\sigma \) . CP sensitivity is notably weakened by \(c^{XY}_{e\mu }\) and \(c^{XY}_{e\tau }\) , suggesting LIV could obscure CP-violation detection.

摘要

Current and future neutrino experiments aim to precisely determine unknown oscillation parameters like the leptonic CP phase and mass hierarchy. Lorentz invariance violation (LIV) may introduce new physics affecting these measurements. This study investigates the impact of non-isotropic CPT-violating ( \(a^{X}_{\alpha \beta }\) ) and CPT-conserving ( \(c^{XY}_{\alpha \beta }\) ) LIV parameters on sensitivity of DUNE to mass hierarchy (MH) and CP violation. We find MH sensitivity remains robust except for \(c^{XY}_{\mu \tau }\) , which reduces sensitivity but stays above \(5\sigma \) . CP sensitivity is notably weakened by \(c^{XY}_{e\mu }\) and \(c^{XY}_{e\tau }\) , suggesting LIV could obscure CP-violation detection.
