Where is the Higgs boson?
A. Aranda, C. Balazs, J. L. Diaz-Cruz
Electroweak precision measurements indicate that the standard model Higgs boson is light and that it could have already been discovered at LEP 2, or might be found at the Tevatron…
Production and Decay of Excited Electrons at the LHC
O. Cakir, C. Leroy, R. Mehdiyev +1
We study single production of excited electrons at the CERN LHC through contact interactions of fermions. Subsequent decays of excited electrons to ordinary electrons and light fer…
Associated Top Quark-Higgs Boson Production at the LHC
S. Dawson, L. H. Orr, L. Reina +1
We compute the O(alpha_s^3) inclusive cross section for the process pp -> t-tbar-h in the Standard Model, at sqrt(s)=14 TeV. The next-to-leading order corrections drastically reduc…
NLO QCD Predictions for associated t-tbar-h production in Hadronic Collisions
S. Dawson, L. H. Orr, L. Reina +1
We present the next-to-leading-order (NLO) QCD corrections to the inclusive total cross section for the production of a Higgs boson in association with a top anti-top quark pair wi…
Are supersymmetric models with large tan(beta) natural ?
Howard Baer, Javier Ferrandis, Xerxes Tata
We point out that, contrary to general belief, generic supersymmetric models are not technically unnatural in the limit of very large values of the parameter tan(beta) when radiati…
Updated Constraints on the Minimal Supergravity Model
H. Baer, C. Balazs, A. Belyaev +3
Recently, refinements have been made on both the theoretical and experimental determinations of the i.) mass of the lightest Higgs scalar, ii.) relic density of cold dark matter in…
Supersymmetric effects on heavy charged Higgs boson production in hadron colliders
Alexander Belyaev, Jaume Guasch, Joan Sola
The production of a heavy supersymmetric charged Higgs boson (M_{H^{\pm}}> 200 GeV) at the Tevatron and at the LHC is studied. We include the leading one-loop quantum effects withi…
QCD corrections to associated t anti-t h production at hadron colliders
S. Dawson, L. Orr, L. Reina +1
We briefly present the status of QCD corrections to the inclusive total cross section for the production of a Higgs boson in association with a top-quark pair within the Standard M…
Radiative Neutralino Decay in Supersymmetric Models
Howard Baer, Tadas Krupovnickas
The radiative decay Z2-> Z1 gamma proceeds at the one-loop level in the MSSM. It can be the dominant decay mode for the second lightest neutralino Z2 in certain regions of paramete…
Relating bottom quark mass in DR-bar and MS-bar regularization schemes
H. Baer, J. Ferrandis, K. Melnikov +1
The value of the bottom quark mass at M_Z in the DR-bar scheme is an important input for the analysis of supersymmetric models with a large value of tan(beta). Conventionally, howe…
Viable models with non-universal gaugino mediated supersymmetry breaking
H. Baer, C. Balazs, A. Belyaev +3
Recently, extra dimensional SUSY GUT models have been proposed in which compactification of the extra dimension(s) leads to a breakdown of the gauge symmetry and/or supersymmetry.…
Updated Constraints on the Minimal Supergravity Model
H. Baer, C. Balazs, A. Belyaev +3
Recently, refinements have been made on both the theoretical and experimental determinations of the i.) mass of the lightest Higgs scalar (m_h), ii.) relic density of cold dark mat…
pp -> ttH, H->tau tau: toward a model independent determination of the Higgs boson couplings at the LHC
Alexander Belyaev, Laura Reina
The possibility of detecting a Higgs boson through several production and decay channels is instrumental to the measurement of its couplings. In this paper we study the pp-> ttH(H-…
Physics potential and experimental challenges of the LHC luminosity upgrade
F. Gianotti, M. L. Mangano, T. Virdee
We discuss the physics potential and the experimental challenges of an upgraded LHC running at an instantaneous luminosity of 10**35 cm-2s-1. The detector R&D needed to operate ATL…
Neutralino relic density in minimal supergravity with co-annihilations
Howard Baer, Csaba Balazs, Alexander Belyaev
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, ch…
Prospects for heavy supersymmetric charged Higgs boson searches at hadron colliders
Alexander Belyaev, David Garcia, Jaume Guasch +1
We investigate the production of a heavy charged Higgs boson at hadron colliders within the context of the MSSM. A detailed study is performed for all important production modes an…
Snowmass 2001: Jet Energy Flow Project
C. F. Berger, E. L. Berger, P. C. Bhat +9
Conventional cone jet algorithms arose from heuristic considerations of LO hard scattering coupled to independent showering. These algorithms implicitly assume that the final state…
Summary: Working Group on QCD and Strong Interactions
E. L. Berger, Stephen Magill, I. Sarcevic +19
In this summary of the considerations of the QCD working group at Snowmass 2001, the roles of quantum chromodynamics in the Standard Model and in the search for new physics are rev…
