Large Phase of B_s-\bar B_s Mixing in Supersymmetric Grand Unified Theories
Bhaskar Dutta, Yukihiro Mimura
We consider the possibility of a large phase of B_s-\bar B_s mixing in supersymmetric SU(5) and SO(10) models. We find that in the SU(5) model, the magnitude of this phase is corre…
Determining the Dark Matter Relic Density in the Minimal Supergravity Stau-Neutralino Coannihilation Region at the Large Hadron Collider
Richard Arnowitt, Bhaskar Dutta, Alfredo Gurrola +3
We examine the stau-neutralino coannihilation (CA) mechanism of the early universe. We use the minimal supergravity (mSUGRA) model and show that from measurements at the Large Hadr…
Proton Decay and Flavor Violating Thresholds in SO(10) Models
Bhaskar Dutta, Yukihiro Mimura, Rabindra Mohapatra
Discovery of neutrino mass has put the spotlight on supersymmetric SO(10) as a natural candidate for grand unification of forces and matter. However, the suppression of proton deca…
Transverse Momentum Spectra of J/ψin Heavy-Ion Collisions
Xingbo Zhao, Ralf Rapp
We investigate J/ψtransverse-momentum (p_t) distributions and their centrality dependence in heavy-ion collisions at SPS and RHIC within the framework of a two-component model, whi…
Realistic Yukawa Textures and SUSY Spectra from Intersecting Branes
Ching-Ming Chen, Tianjun Li, V. E. Mayes +1
We study the possible phenomenology of a three-family Pati-Salam model constructed from intersecting D6-branes in Type IIA string theory on the T^6/(Z2 x Z2) orientifold with some…
Dynamics and Hadronization at intermediate transverse momentum at RHIC
V. Greco, H. van Hees, R. Rapp
The ultra-relativistic heavy-ion program at RHIC has shown that at intermediate transverse momenta (-6 GeV) standard (independent) parton fragmentation can neither de…
