Two Higgs doublet model and leptoquarks constraints from D meson decays

We present new constraints on the two Higgs doublet model (THDM) and the leptoquark model parameters using the leptonic and semileptonic decays of the D meson. Our global analysis includes: the leptonic decay of the Ds meson, the semileptonic decays of the D0 and D + mesons and we have included the...

Summary:We present new constraints on the two Higgs doublet model (THDM) and the leptoquark model parameters using the leptonic and semileptonic decays of the D meson. Our global analysis includes: the leptonic decay of the Ds meson, the semileptonic decays of the D0 and D + mesons and we have included the spectral distribution of the D 0 → K − e + e and D + → K 0 e + e measured by CLEO. We show that D meson decays effectively constrain several variations of the THDM, namely: Type I, Type II, Lepton Specific (LS), Flipped and the aligned model with a Z2 symmetry while complementing second generation constraints for leptoquark models.
