Dark matter (DM) nature is one of the major issues in physics. The search for a DM candidate has motivated known proposal an ultralight scalar field (ULSF). We explore possibility to this ULSF at upcoming European Spallation Source neutrino Super-Beam experiment. have considered recent study case which there could be interaction between and active neutrinos. found that future experimental setup, sensitivity competitive with other physics experiments. show expected main parameter modeling

From a cosmological perspective, scalar fields are well-motivated dark matter and energy candidates. Several possibilities of neutrino couplings with time-varying cosmic field have been investigated in the literature. In this work, we present framework which violations Lorentz invariance (LIV) CPT symmetry sector could arise from an interaction among neutrinos field. Furthermore, some phenomenological aspects constraints concerning type discussed. Potential symmetries at future oscillation...

The precise determination of the leptonic $CP$-phase is one major goals for future generation long baseline experiments. On other hand, if new physics beyond Standard Model exists, a robust such may be challenge. Moreover, it has been pointed out that, in this scenario, an apparent discrepancy measurement at different experiments arise. In work, we investigate Dirac and atmospheric mixing angle ${\ensuremath{\theta}}_{23}$ several long-baseline configurations: ESSnuSB, T2HKK, DUNE-like...

We consider the possible effect of Standard Model Extension (SME) coefficient $(a_L)^Z$ in neutrino propagation and discuss how this can affect DUNE limits on $(a_L)^T$ found elsewhere. Based an analysis that considers both coefficients, we find new constraints for them coming from DUNE. Furthermore, investigate correlations standard oscillation parameters, leptonic $CP-$violating phase, $\delta_{CP}$, atmospheric mixing angle, $\sin^2 \theta_{23}$, with respect to SME coefficients $(a_L)^Z$.
