Probing Neutralino Resonance Annihilation via Indirect Detection of Dark Matter

Howard Baer, Jorge O' Farrill

The lightest neutralino of R-parity conserving supersymmetric models serves as a compelling candidate to account for the presence of cold dark matter in the universe. In the minima…

Neutrino Dimuon Production and the Strangeness Asymmetry of the Nucleon

F. Olness, J. Pumplin, D. Stump +6

We have performed the first global QCD analysis to include the CCFR and NuTeV dimuon data, which provide direct constraints on the strange and anti-strange parton distributions, $s…

FCNC top quark production via anomalous tqV couplings beyond leading order

Nikolaos Kidonakis, Alexander Belyaev

We calculate flavor-changing neutral-current (FCNC) processes involving top-quark production via anomalous tqV couplings at the Tevatron and HERA colliders. We cover the FCNC proce…

Theoretical progress for the associated production of a Higgs boson with heavy quarks at hadron colliders

S. Dawson, C. B. Jackson, L. H. Orr +2

The production of a Higgs boson in association with a pair of top-antitop or bottom-antibottom quarks plays a very important role at both the Tevatron and the Large Hadron Collider…

Linear Collider Capabilities for Supersymmetry in Dark Matter Allowed Regions of the mSUGRA Model

Howard Baer, Alexander Belyaev, Tadas Krupovnickas +1

Recent comparisons of minimal supergravity (mSUGRA) model predictions with WMAP measurements of the neutralino relic density point to preferred regions of model parameter space. We…

Interpretation of the Theta+ as an isotensor pentaquark with weakly decaying partners

Simon Capstick, Philip R. Page, Winston Roberts

The Theta+(1540), recently observed at LEPS, DIANA and CLAS, is hypothesized to be an isotensor resonance. This implies the existence of a multiplet where the Theta++, Theta+ and T…

Next-to-next-to-leading-order soft-gluon corrections in direct photon production

Nikolaos Kidonakis, J. F. Owens

Previous work on soft-gluon resummation for direct photon production is extended to include additional subleading logarithmic terms through O(alpha alpha_s^3) and some representati…

Reach of the Fermilab Tevatron for minimal supergravity in the region of large scalar masses

Howard Baer, Tadas Krupovnickas, Xerxes Tata

The reach of the Fermilab Tevatron for supersymmetric matter has been calculated in the framework of the minimal supergravity model in the clean trilepton channel. Previous analyse…

Direct Detection of Dark Matter in Supersymmetric Models

Howard Baer, Csaba Balazs, Alexander Belyaev +1

We evaluate neutralino-nucleon scattering rates in several well-motivated supersymmetric models, and compare against constraints on the neutralino relic density, BF( b\to sγ) as we…

Using pi_2(1670) -> b_1(1235) pi to Constrain Hadronic Models

Philip R. Page, Simon Capstick

We show that current analyses of experimental data indicate that the strong decay mode pi_2 -> b_1 pi is anomalously small. Non-relativistic quark models with spin-1 quark pair cre…
