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…
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…
Annihilation of light dark matter into photons in model-independent approach
Andriy Badin, Gagik K. Yeghiyan, Alexey A. Petrov
We examine annihilation of light bosonic Dark Matter into pair of photons in model-independent way. We consider the simplest generic Lagrangian describing such process and then com…
Lifetime difference in D^0 - \bar{D^0} mixing within R-parity-violating SUSY
Alexey A. Petrov, Gagik K. Yeghiyan
We re-examine constraints from the recent evidence for observation of the lifetime difference in D^0 - \bar{D}^0 mixing on the parameters of supersymmetric models with R-parity vio…
