Exploring SMEFT Induced Non-Standard Interactions from COHERENT to Neutrino Oscillations
read the original abstract
We investigate the prospects of next-generation neutrino oscillation experiments DUNE, T2HK and JUNO including TAO within Standard Model Effective Field Theory (SMEFT). We also re-interpret COHERENT data in this framework. Considering both charged and neutral current neutrino Non-Standard Interactions (NSIs), we analyse dimension-6 SMEFT operators and derive lower bounds to UV scale $\Lambda$. The most powerful probe is obtained on ${\cal O}_{{ledq}_{1211}}$ with $\Lambda \gtrsim$ 450 TeV due to the electron neutrino sample in T2HK near detector. We find DUNE and JUNO to be complementary to T2HK in exploring different subsets of SMEFT operators at about 25 TeV. We conclude that near detectors play a significant role in each experiment. We also find COHERENT with CsI and LAr targets to be sensitive to new physics up to $\sim$900 GeV.

Non-Standard Neutrino Interactions at Neutrino Experiments and Colliders
Collider searches are generally more constraining than neutrino measurements on simplified models of non-standard neutrino interactions, except possibly for muon-philic leptoquarks and certain heavy neutral leptons.
