A bstract The exquisite capabilities of liquid Argon Time Projection Chambers make them ideal to search for weakly interacting particles in Beyond the Standard Model scenarios. Given their location at CERN ProtoDUNE detectors may be exposed a flux such particles, produced collisions 400 GeV protons (extracted from Super Proton Synchrotron accelerator) on target. Here we point out interesting possibilities that setup offers both long-lived unstable (Heavy Neutral Leptons, axion-like etc) and...
Long-lived particles (LLPs) arise in many theories beyond the Standard Model. These may be copiously produced from meson decays (or through their mixing with LLPs) at neutrino facilities and leave a visible decay signal nearby detectors. We compute expected sensitivity of DUNE liquid argon (LAr) gaseous near detectors (NDs) to light LLP decays. In doing so, we determine backgrounds for both detectors, which have been largely overlooked literature, taking into account angular energy...
We present a detailed analysis of the spectral data Borexino Phase II, with aim exploiting its full potential to constrain scenarios beyond Standard Model. In particular, we quantify constraints imposed on neutrino magnetic moments, non-standard interactions, and several simplified models light scalar, pseudoscalar or vector mediators. Our shows perfect agreement those performed by collaboration moments interactions in same restricted cases expands those, stressing interplay between flavour...
A bstract We derive new constraints on effective four-fermion neutrino non-standard interactions with both quarks and electrons. This is done through the global analysis of oscillation data measurements coherent elastic neutrino-nucleus scattering (CE ν NS) obtained different nuclei. In doing so, we include not only effects physics propagation but also detection cross section in experiments which are sensitive to physics. consider vector axial-vector neutral-current and, for each case,...
Particle physics today faces the challenge of explaining mystery dark matter, origin matter over anti-matter in Universe, neutrino masses, apparent fine-tuning electro-weak scale, and many other aspects fundamental physics. Perhaps most striking frontier to emerge search for answers involves new at mass scales comparable familiar below GeV-scale, or even radically below, down sub-eV scales, with very feeble interaction strength. New theoretical ideas address questions predict such feebly...
A bstract We analyze how neutrino oscillation and coherent elastic neutrino-nucleus scattering data impact the global SMEFT fit. first review mapping between parameters so-called NSI framework, commonly considered in literature. also present a detailed discussion of measurements for normalization fluxes cross sections, that will be affected by new physics, indirectly measured probabilities. then two well-motivated simplified scenarios. Firstly, we study lepton flavour conserving case,...

A bstract Neutrino experiments lie at the edge of intensity frontier and therefore can be exploited to search for new light particles weakly coupled visible sector. In this work we derive constraints on axion-like (ALPs) using data from MicroBooNE experiment, a e + − pairs pointing in direction NuMI absorber. particular, consider addition higher-dimensional effective operators coupling ALP electroweak gauge bosons. These would induce K → πa kaon decay rest absorber, as well decays into...
