Flavor-specific scalar bosons exist in various Standard Model extensions andcouple to a single generation of fermions via a global flavor symmetry breakingmechanism. Given this strategy, we propose a MeV flavor-specific scalar modelin dimension-$5$ operator series, which explains the muon g-2 anomaly andproton radius puzzle by coupling with the muon and down-quark at the same time.The framework is consistent with the null result of high-intensity searches.Specifically, the supernova constraints for muon couplings become weakened byincluding the contribution of down-quark interaction. The parameter space forexplaining muon $g-2$ discrepancy is available when $10\%$ energy deposition isrequired in the energy explosion process in the supernova, but this is ruledout by the $1\%$ energy deposition requirement. We also investigate thesearches for mediator and dark matter and the resulting constraints on viableparameter space such as nuclear physics constraints, direct detection for lightboosted dark matter, and possible CMB constraints. When compared toconventional dark matter production, light dark matter production has twoadditional modifications: bound state formation and early kinetic equilibriumdecoupling. We are now looking into the implications of these effects on therelic density of light dark matter.
