Neutralino Cold Dark Matter in a One Parameter Extension of the Minimal Supergravity Model

Howard Baer, Azar Mustafayev, Stefano Profumo +2

Within the minimal supergravity model (mSUGRA) framework, the expectation for the relic density of neutralinos exceeds the WMAP determination unless neutralinos a) have a significa…

SUSY: Theory Status in the Light of Experimental Constraints

Alexander Belyaev

Supersymmetry remains compelling theory over 30 years in spite of lack of its discovery. It could be already near the corner our days, therefore present and upcoming experiments ar…

Physics Interplay of the LHC and the ILC

LC Study Group, G. Weiglein, T. Barklow +120

Physics at the Large Hadron Collider (LHC) and the International e+e- Linear Collider (ILC) will be complementary in many respects, as has been demonstrated at previous generations…

Higgs Boson Production with Bottom Quarks at Hadron Colliders

S. Dawson, C. B. Jackson, L. Reina +1

We present results for the production cross section of a Higgs Boson with a pair of bottom/anti-bottom quarks, including next-to-leading order (NLO) QCD corrections.

Higgs boson production with one bottom quark jet at hadron colliders

S. Dawson, C. B. Jackson, L. Reina +1

We present total rates and kinematic distributions for the associated production of a single bottom quark and a Higgs boson at the Tevatron and the LHC. We include next-to-leading…

Anomalous tqV couplings and FCNC top quark production

Nikolaos Kidonakis, Alexander Belyaev

We discuss FCNC top quark production via anomalous tqV couplings at the Tevatron and HERA colliders. We calculate higher-order soft-gluon corrections to such processes and demonstr…

Reconciling Neutralino Relic Density with Yukawa Unified Supersymmetric Models

Daniel Auto, Howard Baer, Alexander Belyaev +1

Supersymmetric grand unified models based on the gauge group SO(10) are especially attractive in light of recent data on neutrino masses. The simplest SO(10) SUSY GUT models predic…

The Higgs Working Group: Summary Report 2003

K. A. Assamagan, M. Narain, A. Nikitenko +81

Theoretical progress in Higgs boson production and background processes is discussed with particular emphasis on QCD corrections at and beyond next-to-leading order as well as next…

Two Photon Background and the Reach of a Linear Collider for Supersymmetry in WMAP Favored Coannihilation Regions

Howard Baer, Tadas Krupovnickas, Xerxes Tata

A neutralino relic density in accord with WMAP measurements can be found in the minimal supergravity (mSUGRA) model in several regions of parameter space: the stau co-annihilation…

Indirect, Direct and Collider Detection of Neutralino Dark Matter

Howard Baer, Alexander Belyaev, Tadas Krupovnickas +1

We examine the prospects for supersymmetry discovery in the minimal supergravity (mSUGRA) model via indirect detection of neutralino dark matter. We investigate rates for muon dete…

Onset of asymptotic scaling in deuteron photodisintegration

P. Rossi

We investigate the transition from the nucleon-meson to quark-gluon description of the strong interaction using the photon energy dependence of the differential cross sec…

SUSY Normal Scalar Mass Hierarchy Reconciles (g-2), b->s,gamma and Relic Density

Howard Baer, Alexander Belyaev, Tadas Krupovnickas +1

Recent experimental and theoretical determinations of (g-2)_muon, Omega*h^2 and BF(b->s,gamma) place exceedingly tight constraints on the minimal supergravity (mSUGRA) model. We ad…

Signals from R-parity violating top quark decays at LHC

A. Belyaev, M-H. Genest, C. Leroy +1

We evaluate the potential of the CERN LHC collider to observe rare decays of the top quark in channels involving R-parity violating (RPV) interactions. We stress the importance of…
