Motivated by the long-standing tension in the muon anomalous magnetic moment (AMM) and persistent observations of B-physics anomalies in R D ( * ) and R K ( * ) ratios, we construct a simple two-loop radiative neutrino mass model, and propose a combined explanations of all these apparently disjoint phenomena within this framework. Our proposed model consists of two scalar leptoquarks (LQs), a SU (2) L singletanomalies, respectively. The muon receives chirality-enhanced contribution towards its g − 2 due to the presence of S 1 LQ that accounts for the observed deviation from the Standard Model prediction. Furthermore, we introduce a SU (2) L singlet scalar diquark ω ∼ (6, 1, 2/3), which is necessary to break lepton number and generate neutrino mass radiatively with the aid of S 1 and S 3 LQs. We perform a detailed phenomenological analysis of this set-up and demonstrate its viability by providing benchmark points where a fit to the neutrino oscillation data together with proper explanations of the muon AMM puzzle and flavor anomalies are accomplished while simultaneously meeting all other flavor violation and collider bounds.

The Mu2e Experiment at Fermilab will search for coherent, neutrinoless conversion of negative muons into electrons in the field of an aluminum nucleus. The dynamics of this process is well modelled by a two-body decay, resulting in a mono-energetic electron with an energy slightly below the muon rest mass (∼104.967 MeV). If no events are observed in three years of running, Mu2e will set an upper limit on the ratio between the conversion rate and the capture rate R µe ≤ 6 × 10 −17 (@ 90% C.L.). This will improve the current limit of a factor of 10 4 over previous experiments The experiment complements and extends the current search for µ → eγ decay at MEG as well as the direct searches for new physics at the LHC. Indeed, such a charged lepton flavor-violating reaction probes new physics at a scale inaccessible with direct searches at either present or planned high energy colliders. We briefly present the physics motivation for Mu2e, the current status of the experiment and the design of the muon beamline and the detector, devoting particular attention to the R&D phase, simulation and test carried out to prove the validity of the electromagnetic calorimeter configuration.
