Description
Neutrino oscillation in the matter could be affected by the sub-dominant, yet unknown, non-standard interactions (NSI). The observed shift in $\delta_{CP}$ value observed for NOvA in case of standard model (SM) and NSIs arising simultaneously from two different off-diagonal sectors, e−μ and e−τ could be attributed to the beyond standard model physics. We derive constraints on the NSI sectors using the combined datasets of NOνA and T2K. Our analysis reveals a significant impact that dual NSIs may have on the sensitivity of standard CP phase $\delta_{CP}$ and atmospheric mixing angle $\theta_{23}$. Here we assume that the presence of leptoquarks ($U_3$) to account for the apparent difference in the experimental observations of $\delta_{CP}$ measurement by NOvA and T2K using $\epsilon_{e\mu}$. Furthermore, using this input we obtain the Lepton Flavour violation (LFV) muon decay decay branching ratios: B(μ→eγ)≤10$^{−18}$, B(μ→eee)≤10$^{−21}$ and B(μ→e)Ti≤10$^{−19}$ which could be probed in the future experiments.
