Simian immunodeficiency virus (SIV) is closely related to human immunodeficiency virus (HIV), their matrix antigens (MAs) sharing some 50% sequence identity. MA is a component of Pr55Gag, the sole protein required for assembly of the virion shell. MA targets Pr55 to the plasma membrane, and facilitates incorporation of the virus envelope protein and(More)
We present the report of the hadronic working group of the BOOST2010 workshop held at the University of Ox-ford in June 2010. The first part contains a review of the potential of hadronic decays of highly boosted particles as an aid for discovery at the LHC and a discussion of the status of tools developed to meet the challenge of reconstructing and(More)
We perform a detail theoretical study including decays and jet fragmentation of all the important modes of the single top quark production and all basic background processes at the upgraded Tevatron and LHC colliders. Special attention was paid to the complete tree level calculation of the QCD fake background which was not considered in the previous(More)
The standard model of particle physics contains parameters--such as particle masses--whose origins are still unknown and which cannot be predicted, but whose values are constrained through their interactions. In particular, the masses of the top quark (M(t)) and W boson (M(W)) constrain the mass of the long-hypothesized, but thus far not observed, Higgs(More)
Recently, refinements have been made on both the theoretical and experimental determinations of i.) the mass of the lightest Higgs scalar, ii.) the relic density of cold dark matter in the universe, iii.) the branching fraction for the radiative b → sγ decay, iv.) the muon anomalous magnetic moment, and v.) the flavor violating decay Bs → µ + µ −. In this(More)
Shape interrogation methods are of increasing interest in geometric modeling as well as in computer graphics. Originating 20 years ago from CAD/CAM applications where " class A " surfaces are required and no surface imperfections are allowed, shape interrogation has become recently an important tool for various other types of surface representations such as(More)
We evaluate the relic density of neutralinos in the minimal supergravity (mSUGRA) model. All 2 → 2 neutralino annihilation diagrams, as well as all processes involving sleptons, charginos, neutralinos and third generation squarks are included. Rel-ativistic thermal averaging of the velocity times cross sections is performed. We find that co-annihilation(More)
A new implementation of the general PQCD formalism of Collins, including heavy quark mass effects, is described. Important features that contribute to the accuracy and efficiency of the calculation of both neutral current (NC) and charged current (CC) processess are explicitly discussed. This new implementation is applied to the global analysis of the full(More)
