Description
Extra dimensions (ED) offer a valuable tool for constructing intricate models and exploring potential new physics phenomena. Our focus is to extand Standard Model (SM) by introducing an U (1) Lµ −Lτ gauge group in the framework of ED, which serves as a compelling initiative aimed at addressing the muon (g - 2) anomaly. In this model, only the Kaluza-Klein (KK) modes of the extra dimensional gauge boson traverse the bulk, while Standard Model particles remain localized on the SM brane assuming a
compactification ‘radius’ of order R^−1 form 1 to 1000 MeV. We present constraints on the mnKK − g ′ , where mnKK is the mass of the extra-dimensional gauge boson for a particular KK mode, and g ′ is the interaction coefficient between the extra-dimensional gauge boson and SM fermions. These constraints are derived from ν − e elastic scattering measurements at DUNE ND (Future based experiment) and compare them with those from other ν − e elastic scattering experiments, CHARM II, TEXONO and BOREXINO. Our results indicate that the DUNE Near Detector can provide the most stringent bounds for extra-dimensional gauge boson masses in the range of 1 to 1000 MeV.
