Gauge-boson scattering signals at the LHC

We have extended our earlier treatment of the gauge-boson scattering with radiative corrections in the standard model at supercollider energies, and computed the rates for gauge-boson scattering modes in $pp$ collisions leading to the final states $W^+W^-$, $ZZ(4l)$, $ZZ(2l2ν)$, $W^\pm Z$, and $W^\pm W^\pm $. Our results at the LHC \hbox{energy} of $\sqrt{s}=14$~TeV for $m_H=1000$~GeV are compared with those recently obtained by Bagger {\it et al.} These results will be useful in the search for the Higgs bosons at supercollider energies as well as for experimentally distinguishing the standard model from non-minimal Higgs models.

Theory Aspects of Double-Spin Asymmetries in Proton-Nucleon Collisions

The study of two spin asymmetries in hadron-hadron collisions probes the details of fundamental particle interactions in ways infeasible to machines with unpolarized collisions. Within reach is how the proton spin is distributed among its constituents through $ΔG$ and $Δ\bar{q}$. Measuring couplings, furthering our understanding jet structure and uncovering new physics are all among the possibilities available at polarized colliders. Spin physics may also deepen our understanding of higher twist behavior and the transition between perturbative and nonperturbative physics. An overview of the double spin physics is presented in this report.

A Collection of Polarized Parton Densities

A significant number of parameterizations for the polarized parton densities have appeared in the literature. Using the CTEQ evolution package, these distributions have been evolved consistently preparatory to compilation into an integrated package in the spirit of PDFLIB by Plothow-Besch. Here, a comparison of a few of the more recent distributions are made. (Presented during the Workshop on the ``Prospects of Spin Physics at HERA'' held at DESY-Zeuthen, Germany, 28-31 August 1995.)

Single Spin Asymmetries at RHIC

One purpose of this meeting is to assess the physics potential of HERA-N Stage I. To develop a reasonable perspective, it is useful to look at other spin experiments. For completeness, this report discusses some of the single spin physics that has appeared in studies relating to the Relativistic Heavy Ion Collider (RHIC). (Talk presented during the meeting on ``The Measurement of Singly Polarized Collisions at HERA'' held at DESY-Zeuthen, Germany, 31 August-1 September 1995.)

On pi-pi Correlations in Polarized Quark Fragmentation Using the Linear Sigma Model

Using the linear sigma model to describe quark--pion interactions, we compute polarization asymmetries in quark fragmentation. We show that the effects of transverse quark polarizations appear in the correlation between the two leading pions in a jet produced by the fragmentation of a quark. Such asymmetries provide a window to the nature of chiral symmetry breaking in QCD.
