Associated Higgs Production in the MSSM

S. Dawson, L. Reina

We investigate the inclusive production of the Higgs bosons of the minimal supersymmetric model with a heavy quark pair, ( and ), in e^+e^- collisions at hi…

Covariant Wave Function Reduction and Coherent Decays of Kaon Pair

Bernd A. Berg

The recently developed relativistically covariant formulation of wave function reduction is illustrated for Lipkin's proposal to study CP violation in the coherent decay of kaon pa…

Probing Minimal Supergravity at the CERN LHC for Large

Howard Baer, Chih-hao Chen, Manuel Drees +2

For large values of the minimal supergravity model parameter , the tau lepton and the bottom quark Yukawa couplings become large, leading to reduced masses of -sleptons a…

kt Effects in Direct-Photon Production

L. Apanasevich, C. Balazs, C. Bromberg +10

We discuss the phenomenology of initial-state parton-kt broadening in direct-photon production and related processes in hadron collisions. After a brief summary of the theoretical…

Searching for Bottom Squarks at Luminosity Upgrades of the Fermilab Tevatron

Howard Baer, P. G. Mercadante, Xerxes Tata

Because of their Yukawa interactions, third generation squarks may be substantially lighter than those of the first two generations. Assuming that $\tb_1 \to b\tz_1$ and $\tz_1$ es…

QCD Corrections to Associated Higgs Boson-Heavy Quark Production

Sally Dawson, Laura Reina

We compute the O(alpha_s) QCD corrections to the inclusive process e^+e^- --> t \bar t h. Although the total rate is small, it has a distinctive experimental signature and can pote…

The Reach of CERN LEP2 and Fermilab Tevatron Upgrades for Higgs Bosons in Supersymmetric Models

Howard Baer, B. W. Harris, Xerxes Tata

Luminosity upgrades of the Fermilab Tevatron pbar-p collider have been shown to allow experimental detection of a Standard Model (SM) Higgs boson up to GeV via…

LHC Reach for Gauge Mediated Supersymmetry Breaking Models Via Prompt Photon Channels

Howard Baer, Pedro G. Mercadante, Frank Paige +2

We evaluate the supersymmetry reach of the Large Hadron Collider within the gauge-mediated low energy supersymmetry breaking framework, assuming that a neutralino is the second lig…

Lattice Determination of Heavy-Light Decay Constants

MILC Collaboration, C. Bernard, T. DeGrand +9

We report on the MILC collaboration's calculation of , , , , and their ratios. Our central values come from the quenched approximation, but the quenchin…

A Heavy Gluino as the Lightest Supersymmetric Particle

H. Baer, K. Cheung, J. F. Gunion

We consider the possibility that the lightest supersymmetric particle is a heavy gluino. After discussing models in which this is the case, we demonstrate that the gluino-LSP could…

Supersymmetry Reach of Tevatron Upgrades: The Large Case

Howard Baer, Chih-hao Chen, Manuel Drees +2

The Yukawa couplings of the tau lepton and the bottom quark become comparable to, or even exceed, electroweak gauge couplings for large values of the SUSY parameter . As a r…

Gauge and Yukawa Unification with Broken R-Parity

Marco A. Diaz, J. Ferrandis, Jorge C. Romao +1

We study gauge and Yukawa coupling unification in the simplest extension of the Minimal Supersymmetric Standard Model (MSSM) which incorporates R-Parity violation through a bilinea…

Jet photoproduction and the structure of the photon

B. W. Harris, J. F. Owens

Various jet observables in photoproduction are studied and compared to data from HERA. The feasibility of using a dijet sample for constraining the parton distributions in the phot…

An Investigation of Uncertainties in the QCD NLO Predictions of the Inclusive Jet Cross Section in pbarp Collisions at sqrt(s) = 1.8 TeV and 630 GeV

B. Abbott, I. A. Bertram, M. Bhattacharjee +6

Uncertainties in the NLO calculation of the inclusive jet cross section due to the choice of renormalization scale, parton distribution functions and clustering algorithm are explo…

Study of the Uncertainty of the Gluon Distribution

J. Huston, S. Kuhlmann, H. L. Lai +4

The uncertainty in the calculation of many important new processes at the Tevatron and LHC is dominated by that concerning the gluon distribution function. We investigate the uncer…
