New Physics Contribution to within R-Parity Violating Supersymmetric Models

Gagik Yeghiyan

We re-visit the problem of New Physics (NP) contribution to the branching ratio of the decay in light of the recent observation of this decay by LHCb. We consider…

Dominant 1/m_c Contribution To The Mass Difference in D0-D0bar Mixing

Gagik Yeghiyan

We re-visit the problem of non-perturbative contribution to the mass difference in D0-D0bar mixing within the Standard Model (SM). There are two known approaches to take this contr…

Relating B_s Mixing and B_s -> mu+mu- with New Physics

Eugene Golowich, JoAnne Hewett, Sandip Pakvasa +2

We perform a study of the Standard Model (SM) fit to the mixing quantities , and in order to bound contributions of New Physics to mixing. We th…

The flavor puzzle in multi-Higgs models

Andrew E. Blechman, Alexey A. Petrov, Gagik Yeghiyan

We reconsider the flavor problem in the models with two Higgs doublets. By studying two generation toy models, we look for flavor basis independent constraints on Yukawa couplings…

Upsilon Decays into Scalar Dark Matter

Gagik K. Yeghiyan

We examine decays of a spin-1 bottomonium into a pair of light scalar Dark Matter (DM) particles, assuming that Dark Matter is produced due to exchange of heavy degrees of freedom.…

Lifetime difference in - mixing within R-parity-violating SUSY

Gagik K. Yeghiyan

We re-examine constraints from the evidence for observation of the lifetime difference in - mixing on the parameters of supersymmetric models with R-parity violati…
