Charged lepton flavor violation in light of muon $$g-2$$

Abstract The recent confirmation of the muon $$g-2$$ g - 2 anomaly by Fermilab experiment may harbinger a new era in $$\mu $$ μ and $$\tau τ physics. In context general two Higgs doublet model, discrepancy can be explained via one-loop exchange sub-TeV exotic scalar pseudoscalars, namely H A , that have flavor changing neutral couplings $$\rho _{\tau \mu }$$ ρ _{\mu \tau at $$\sim 20$$ ∼ 20 times usual tau Yukawa coupling, $$\lambda _\tau λ . Taking _{\ell \ell ^\prime }\sim \lambda _{ \mathrm min(\ell )}$$ ℓ ′ m i n ( , ) we show above solution to then predicts enhanced rates various charged lepton violating processes, which should accessible upcoming experiments.
