Cosmic ray signals from dipole-interacting dark matter annihilation are considered in the positron, antiproton, and photon channels. The predicted positron channel could nicely account for excess of fraction Fermi LAT, PAMELA, HEAT, AMS-01 experiments mass larger than 100 GeV with a boost (enhancement) factor 30--80. No antiproton over proton ratio at also gives severe restriction this scenario. With factors, Galactic halo as monoenergetic gamma-ray lines (monochromatic photons) region close...
An appended sector of two octet-colored scalars, each an electroweak doublet, is interesting extension the simple Higgs doublet model motivated by minimal flavor violation. Their rich CP violating interaction gives rise to a sizable electron electric dipole moment, besides quark moment via two-loop contribution Barr-Zee mechanism.
The model (Lagrangian) with a peculiar extra U(1)is clearly presented. assigned U(1) gauge charges give strong constraint to build Lagrangians. Z' discovery limits are estimated and predicted at the Tevatron LHC. new contributions of muon anomalous magnetic moment investigated one two loops, we predict that deviation from standard may be explained. electron electric dipole could also generated because explicit CP violation effect in Higgs sector, sizable contribution is expected for...
A triplet dark matter candidate from thermal leptogenesis is considered with building a model. The model based on the standard two-Higgs-doublet and seesaw mechanism Higgs triplets. parameters (couplings masses) are adjusted for observed small neutrino mass leptogenesis. Dark particles can annihilate decay in this time evolution of number governed by (co)annihilations expanding universe, its constrained relic density. into final states three leptons (two charged one neutrino). We investigate...
The next-to-leading order QCD corrections are calculated for the pair annihilation of spin-1 dark matter (DM) by dimensionally regularizing both ultraviolet and infrared singularities in nonrelativistic ($v\ensuremath{\ll}1$) limit. complete $O({\ensuremath{\alpha}}_{s})$ correction is about 8% due to massless gluon contribution. An extra 5% will be added if there a new interaction from massive approximately same mass as DM particle. could result sizable shift constrained relic density measurements.
