“…We now derive future sensitivities for the axial model, chiral model, and the 2HDM using the following projections for dark photon searches: APEX [27], Belle II [111], Dark-Light [112], FASER [113], HPS [114], LHCb [61,65,67], MESA [56], NA62 [74], SeaQuest [60], VEPP-3 [55], and Yemilab [73]. Projections from Mu3e [57] are not included as the µbremsstralhung approximation is not expected to hold within the relevant mass range.…”

In this work, we explore new spin-1 states with axial couplings to the standard model fermions. We develop a data-driven method to estimate their hadronic decay rates based on data from τ decays and using SU(3) flavor symmetry. We derive the current and future experimental constraints for several benchmark models. Our framework is generic and can be used for models with arbitrary vectorial and axial couplings to quarks. We have made our calculations publicly available by incorporating them into the DarkCast package, see https://gitlab.com/darkcast/releases.

“…This makes it capable of enhancing the sensitivity of Borexino by up to an order of magnitude. It is also important to note that the upcoming installation of the liquid scintillator-based detector (LSC) at Yamilab [55,56] will bring significant improvements to solar neutrino measurements compared to the current Borexino experiment, which can therefore provide better sensitivities for NSI model searches. The solid lines represent the limits including interference, while the dotted lines show the limits excluding interference for XENONnT.…”

Neutrino-electron scattering experiments play a crucial role in investigating the non-standard interactions of neutrinos. In certain models, these interactions can include interference terms that may affect measurements. Next-generation direct detection experiments, designed primarily for dark-matter searches, are also getting sensitive to probe the neutrino properties. We utilise the data from XENONnT, a direct detection experiment, and Borexino, a low-energy solar neutrino experiment, to investigate the impact of interference on non-standard interactions. Our study considers models with an additional U(1) B-L , including U(1), U(1) L e - L µ , and U(1) L e - L τ , to investigate the impact of interference on non-standard neutrino interactions. We demonstrate that this interference can lead to a transition between the considered non-standard interaction models in the energy range relevant to both the XENONnT and Borexino experiments. This transition can be used to distinguish among the considered models if any signals are observed at direct detection or neutrino experiments. Our findings underscore the importance of accounting for the interference and incorporating both direct detection and solar neutrino experiments to gain a better understanding of neutrino interactions and properties.

“…When m Z Q < 2 m e , the new boson Z Q can also decay into three photons. The decay width for this process can be found in [20]. Nevertheless, the partial decay width for Z Q → 3γ is neglegibly small for the models and mass range of interest in this paper and hence, we refrain from including it into our calculations.…”

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.
