Detecting Sleptons at Hadron Colliders and Supercolliders

H. Baer, C. Chen, F. Paige +1

We study the prospects for detecting the sleptons of the Minimal Supersymmetric Standard Model at hadron colliders and supercolliders. We use ISAJET 7.03 to simulate charged slepto…

Production of CP-Odd Higgs Bosons with Large Transverse Momentum at Hadron Supercolliders

Chung Kao

A two Higgs doublet model is employed to study the production of a CP-odd Higgs boson () associated with a large transverse momentum jet () at hadron supercolliders. The cros…

Pion Form Factors at Intermediate Momentum Transfer in a Covariant Approach

A. Szczepaniak, A. G. Williams

We study the pion electromagnetic and transition form factors at intermediate momentum transfer. We calculate soft, nonperturbative corrections to the leading per…

Dynamical chiral symmetry breaking and confinement with an infrared-vanishing gluon propagator?

Frederick T. Hawes, Craig D. Roberts, Anthony G. Williams

We study a model Dyson-Schwinger equation for the quark propagator closed using an {\it Ansatz} for the gluon propagator of the form \mbox{} and two…

The Charm Content of W+1 Jet Events as a Probe of the Strange Quark Distribution Function

U. Baur, F. Halzen, S. Keller +2

We investigate the prospects for measuring the strange quark distribution function of the proton in associated plus charm quark production at the Tevatron. The quark sign…

Production of Boson Pairs at Photon Linear Colliders

Duane A. Dicus, Chung Kao

The pair production rate in high energy collisions is evaluated with photons from laser backscattering. We find that searching for the Standard Model Higgs boson with a m…

Impact of QCD Corrections on the Search for the Intermediate Mass Higgs Boson

Bob Bailey, Dirk Graudenz

Using next-to-leading-log calculations of Higgs production and hadronic two photon production, a signal and background study in the intermediate mass range of the Higgs boson is do…

Aspects of Chargino-Neutralino Production at the Tevatron Collider

Howard Baer, Chung Kao, Xerxes Tata

We have used ISAJET 7.0/ISASUSY 1.0 to evaluate the rates and study distributions for trilepton events from the leptonic decays of charginos and neutralinos produced at the Fermila…

Measuring the Longitudinally Polarized Proton Gluon Distribution using Photoproduction Processes

S. Keller, J. F. Owens

Little information is known about the polarization of gluons inside a longitudinally polarized proton. We investigate the sensitivity of photoproduction experiments with both beam…

An Estimate of Jet Activity in Events

H. Baer, C. H. Chen, M. H. Reno

We present a calculation of jet activity associated with pair production of top quarks at hadron colliders and supercolliders. Our approach is based upon a merger of $2\rightarrow…

New Signals for Gluinos and Squarks of Supergravity at the Tevatron Collider

H. Baer, C. Kao, X. Tata

Within the supergravity framework, sleptons are expected to be considerably lighter than squarks if gluinos and squarks are approximately degenerate. This can lead to a significant…

QCD Corrections to Hadronic Production with Non-standard Couplings

U. Baur, T. Han, J. Ohnemus

The process $p \pbar \rightarrow W^{\pm}γ+ X \rightarrow \ell^\pm νγ+ X$ is calculated to for general conserving couplings. At the Tevatron center of mas…
