Msugra Dark Matter and the B Quark Mass
We extend the commonly used mSUGRA framework to allow complex soft terms. We show how these phases can induce large changes of the SUSY threshold corrections to the b quark mass and affect the neutralino relic density predictions of the model. We present some specific models with large SUSY phases which can accommodate the fermion electric dipole moment constraints and a neutralino relic densit...
متن کاملTHE ROLE OF QUARK POLARIZATION IN HEAVY QUARK FRAGMENTATION
We calculate the exact fragmentation functions for c and b quark fragmentation taking into account the spin orientation of the initial heavy quark in the form of analytical and rather simple expressions. Our calculations show that spin orientation may have an important effect on the fragmentation spectrum. This effect is more striking in the cases of c ?D, D*; c? ? , ? , and ?B , B *.
متن کاملDark matter Search and the Scalar Quark Contents of the Nucleon
We present lattice QCD simulation results from the European Twisted Mass Collaboration (ETMC) for the light, strange and charm quark contents of the nucleon. These quantities are important ingredients to estimate the cross-section for the detection of WIMPs as Dark Matter candidates. By employing a particular lattice QCD formulation, i.e. twisted mass fermions, accurate results of the light and...
متن کاملLight Stops in the MSSM : Implications for Photino Dark Matter and Top Quark Decay
We consider the viability of the minimal supersymmetric standard model with a light (m ˜ t 1 < 45 GeV) stop. In order for its relic abundance to be cosmologically significant, the photino as dark matter must be quite close in mass to the stop, (m ˜ t 1 − m ˜ γ) ≃ 3 − 7 GeV. However, as we show, the photino despite its low mass is virtually undetectable by either direct or indirect means. We als...
متن کاملDiscovering Domains Mediating Protein Interactions
Background: Protein-protein interactions do not provide any direct information regarding the domains within the proteins that mediate the interactions. The majority of proteins are multi domain proteins and the interaction between them is often defined by the pairs of their domains. Most of the former studies focus only on interacting domain pairs. However they do not consider the in...
