Correlation between direct dark matter detection and Br(B_s -> mu mu) with a large phase of B_s - anti-B_s mixing
Bhaskar Dutta, Yukihiro Mimura, Yudi Santoso
We combine the analyses for flavor changing neutral current processes and dark matter solutions in minimal-type supersymmetric grand unified theory (GUT) models, SO(10) and SU(5),…
Prospects for Indirect Detection of Sneutrino Dark Matter with IceCube
Rouzbeh Allahverdi, Sascha Bornhauser, Bhaskar Dutta +1
We investigate the prospects for indirect detection of right-handed sneutrino dark matter at the IceCube neutrino telescope in a extension of the MSSM. The capture and…
Mirage in the Sky: Non-thermal Dark Matter, Gravitino Problem, and Cosmic Ray Anomalies
Bhaskar Dutta, Louis Leblond, Kuver Sinha
Recent anomalies in cosmic rays could be due to dark matter annihilation in our galaxy. In order to get the required large cross-section to explain the data while still obtaining t…
Sneutrino Dark Matter and the Observed Anomalies in Cosmic Rays
Rouzbeh Allahverdi, Bhaskar Dutta, Katherine Richardson-McDaniel +1
We revisit sneutrino dark matter in light of the recent results from the PAMELA and ATIC experiments. In the U(1)_B-L extension of the minimal supersymmetric standard model the rig…
Penguin Contribution to the Phase of B_s-\bar B_s Mixing and B_s -> mu mu in Grand Unified Theories
Bhaskar Dutta, Yukihiro Mimura
We investigate the possibility of a large B_s-\bar B_s mixing phase in the context of grand unified theory (GUT) models, e.g., SO(10) and SU(5). In these models, we find that a lar…
