Abstract In this work we investigate the implication of low-energy precision measurements on the quark-lepton charged currents in general neutrino interactions with sterile neutrinos in effective field theories. The physics in low-energy measurements is described by the low-energy effective field theory extended with sterile neutrinos (LNEFT) defined below the electroweak scale. We also take into account renormalization group running and match the LNEFT onto the Standard Model (SM) effective field theory with sterile neutrinos (SMNEFT) to constrain new physics (NP) above the electroweak scale. The most sensitive low-energy probes are from leptonic decays of pseudoscalar mesons and hadronic tau lepton decays in terms of precise decay branching fractions, the lepton flavor universality and the Cabibbo-Kobayashi-Maskawa (CKM) unitarity. We also consider other constraints including nuclear beta decay. The constraints on charged current operators are generally stronger than the ones for quark-neutrino neutral current operators. We find that the most stringent bounds on the NP scale of lepton-number-conserving and lepton- number-violating operators in SMNEFT are 74 (110) TeV and 9.8 (13) TeV, respectively, for the operators with down (strange) quark.

The 760 ton liquid argon ICARUS T600 detector performed a successful threeyear physics run at the underground LNGS laboratories, studying neutrino oscillations with the CNGS neutrino beam and searching for atmospheric neutrino interactions in cosmic rays. A sensitive search for LSND like anomalous ve appearance has been performed, contributing to constrain the allowed parameters to a narrow region around Δm2 ~ eV2, where all the experimental results can be coherently accommodated at 90% C.L.. After a significant overhauling, the T600 detector will be exposed at Fermilab to the Booster Neutrino Beam acting as the far detector, in order to search for sterile neutrino within the SBN program. In the present contribution, the ICARUS LNGS achievements, the present status of the detector and the ongoing analyses also finalized to the next physics run at Fermilab will be addressed.

We have considered the ‘neutrino counting’ reaction [Formula: see text]. We restrict to V, A Lorentz structure of weak neutral interaction (WNI), allow many Z bosons to mediate WNI and νi to be different from νj. We derive the expression for differential cross section by allowing the polarizations of e+ and e− but summing over the polarizations of final photons. From the study of differential cross section with polarized and unpolarized beams three different coupling constant combinations can be determined. A definite relation between these observables and the observables in [Formula: see text] scatterings is suggested as a test of single-Z-boson hypothesis. Similarly another test relates observables in [Formula: see text] to those of [Formula: see text] scatterings. By assuming universality a test for presence of nondiagonal neutrino neutral currents (NDνNC’s) is also pointed out. The effects of presence of wrong-handed (anti-) neutrinos on our tests are also discussed. As a by-product, we find a way to determine number of neutrino types, in the case i≠j, assuming universality.
