“…Such scenarios have been probed through various physical processes, e.g., Neutrino Trident Production [44][45][46][47], Supernova limits [48][49][50][51], White Dwarf Cooling [52], Coherent Elastic Neutrino Nucleus Scattering [53], and rare Kaon decay [54,55]. Also, such models have been surveyed in the light of various experiments, e.g., in IceCube [56,57], Belle-II [58][59][60][61][62], LHC [63,64], e − e + colliders [65,66], e − p colliders [65,67], MUonE [61], NA64-(e, µ) [68][69][70][71][72][73], M 3 [74], and (other) Beam Dump Experiments [75][76][77][78] (see also [79]). 1 In this paper, we will focus on an extension of the vanilla U (1) Lµ−Lτ scenario in four dimensions into five dimensions (5D), where one minuscule compact spatial direction is introduced.…”

The neutrino-electron scattering process is a powerful tool to explore new physics beyond the standard model. Recently the possibility of DUNE Near Detector (ND) to constrain various new physics scenarios using this process have been highlighted in the literature. In this work, we consider the most general U(1) model and probe the constraints on the mass and coupling strength of the additional Z′ from ν − e scattering at DUNE ND. The presence of the Z′ gives rise to extra interference effects. In the context of the general U(1) model, the destructive interference can occur in either neutrino or anti-neutrino channel or for both or none. This opens up the possibilities of getting four different type of signal in the neutrino and ant-neutrino runs of DUNE. We perform the analysis using both the total rate and binned events spectrum. Our results show that in a bin by bin analysis the effect of destructive interference is less compared to the analysis using total rate. We present the bounds on the mZ′− gX plane from ν − e scattering measurements at DUNE ND and compare these with those obtained from other ν − e scattering, COHERENT, and beam dump experiments. We show that the DUNE ND can give the best bound for certain mass ranges of Z′.

Inelastic dark matter with moderate splittings, $$ \mathcal{O} $$ O (few to 150) keV, can upscatter to an excited state in the Earth, with the excited state subsequently decaying, leaving a distinctive monoenergetic photon signal in large underground detectors. The photon signal can exhibit sidereal-daily modulation, providing excellent separation from backgrounds. Using a detailed numerical simulation, we examine this process as a search strategy for magnetic inelastic dark matter with the dark matter mass near the weak scale, where the upscatter to the excited state and decay proceed through the same magnetic dipole transition operator. At lower inelastic splittings, the scattering is dominated by moderate mass elements in the Earth with high spin, especially 27Al, while at larger splittings, 56Fe becomes the dominant target. We show that the proposed large volume gaseous detector CYGNUS will have excellent sensitivity to this signal. Xenon detectors also provide excellent sensitivity through the inelastic nuclear recoil signal, and if a future signal is seen, we show that the synergy among both types of detection can provide strong evidence for magnetic inelastic dark matter. In the course we have calculated nuclear response functions for elements relevant for scattering in the Earth, which are publicly available on GitHub.

We consider an experiment to search for dark sector particles in invisible (or semi-invisible) decays of neutral mesons M0=π0, η, η′, ω, f2(1270), which produced the charge-exchange reactions π−+(A,Z)→M0+(A,Z−1);M0→ of high-energy pions (or kaons) on a nuclei target in the NA64 experiment at the CERN SPS. This reaction chain would lead to a striking signature of the signal event—the complete disappearance of the beam energy in the setup []. Using data obtained from the measurements at IHEP (Protvino) and Fermilab (Batavia) we show that the integral cross sections σ for the production of the M0 s slightly deviate from the phenomenological formula σ∼Z2/3, where Z is the nuclei charge. In particular, we present the formulas for the differential and integral cross sections that explicitly depend on the Mandelstam and Z variables. Derived formulas are used to predict the M0 yield as a function of beam energy for several target nuclei, and to estimate the projection sensitivity for the proposed search in the dark vector portal model. Sensitivity to different decay modes of M0s is explored. Published by the American Physical Society 2024
