“…On the other hand, the proposed detectors at the ESS will explore larger portions of untested parameter space. This is particularly true for the L µ − L τ model where the detector exploiting Xe and CsI will be able to test the region 3 m Z /MeV 60, where the Z is able to explain the anomalous muon magnetic moment measurements [62][63][64] and the Xenon1T excess [65,66]. Moreover, all the detectors at the ESS will be able to test a specific model [67] that can explain peculiar features observed in the cosmic neutrino spectrum by IceCube [68].…”

“…In particular, these detectors will reach unexplored regions in the range 3 < m Z /MeV < 70 and may be able to completely exclude the solution to the anomalous magnetic moment of the muon for m Z < 30 MeV. Furthermore, it is interesting to note that in specifically extended models [66] there is a region which could explain the excess of low energy electrons observed by the Xenon1T experiment [65] (yellow band) and simultaneously the (g − 2) µ anomaly (red region). The detectors at the ESS have the potential to probe the values of (m Z , g Z ) that explain both the (g − 2) µ and the Xenon1T excess, and also the reference points of a specific model [67] explaining peculiar features observed in the cosmic neutrino spectrum by the IceCube collaboration [68] (also shown in Fig.…”

“…In the red region the model explains at 2σ the anomalous magnetic moment of the muon[62][63][64]. The yellow band shows the region that can explain the Xenon1T excess[65] in some specifically extended L µ − L τ model[66], while the black diamonds refer to a model[67] that explain the cosmic neutrino spectrum features observed by IceCube[68].…”

Future experiments dedicated to the detection of Coherent Elastic Neutrino-Nucleus Scattering may be powerful tools in probing light new physics. In this paper we study the sensitivity on light Z mediators of two proposed experiments: a directional low pressure Time Projection Chamber detector, νBDX-DRIFT, that will utilize neutrinos produced at the Long Baseline Neutrino Facility, and several possible experiments to be installed at the European Spallation Source. We compare the results obtained with existing limits from fixed-target, accelerator, solar neutrino and reactor experiments. Furthermore, we show that these experiments have the potential to test unexplored regions that, in some case, could explain the anomalous magnetic moment of the muon or peculiar spectral features in the cosmic neutrino spectrum observed by IceCube.

“…In part this is because they can be involved in the solution of some unsolved conundrums we face today. They have been evoked in association with dark matter models [1][2][3][4][5][6][7], with the muon anomalous magnetic dipole moment [8,9], with the MiniBooNE excess of electron like events [10,11] and to alleviate the reported tension in the Hubble constant [12].…”

Abelian U (1) gauge group extensions of the Standard Model represent one of the most minimal approaches to solve some of the most urgent particle physics questions and provide a rich phenomenology in various experimental searches. In this work, we focus on baryophilic vector mediator models in the MeV-to-GeV mass range and, in particular, present, for the first time, gauge vector field decays into almost arbitrary hadronic final states. Using only very little theoretical approximations, we rigorously follow the vector meson dominance theory in our calculations. We study the effect on the total and partial decay widths, the branching ratios, and not least on the present (future) experimental limits (reach) on (for) the mass and couplings of light vector particles in different models. We compare our results to current results in the literature. Our calculations are publicly available in a python package to compute various vector particle decay quantities in order to describe leptonic as well as hadronic decay signatures for experimental searches.

“…Studies related to self-interacting dark matter in a typical WIMP (weakly interacting massive particle) paradigm are prevalent in literature (see, for example, [14][15][16][17][18] for some of the recent works). On the other hand, proposals for self-interacting dark matter with freeze-in production are somewhat limited and can be found in refs.…”

Self-interacting freeze-in dark matter in a singlet doublet scenario

We examine the non-thermal production of dark matter in a scalar extended singlet doublet fermion model where the lightest admixture of the fermions constitutes a suitable dark matter candidate. The dark sector is non-minimal with the MeV scale singlet scalar, which is stable in the Universe lifetime and can mediate the self-interaction for the multi-GeV fermion dark matter mitigating the small scale structure anomalies of the Universe. If the dark sector is strongly coupled, it undergoes internal dark thermal equilibrium after freeze-in production, and we end up with suppressed relic abundance for the fermion dark matter in a radiation dominated Universe. In contrast, the presence of a modified cosmological phase in the early era drives the fermion dark matter to satisfy nearly the whole amount of observed relic. It also turns out that the assumption of an unconventional cosmological history can allow the GeV scale dark matter to be probed at LHC from displaced vertex signature with improved sensitivity.
