Nuclear Dependence in Drell-Yan Transverse Momentum Distribution

Xiaofeng Guo

We calculate the nuclear enhancement in Drell-Yan transverse momentum distribution in hadron-nucleus collisions. In terms of multiple scattering picture, we compute the contributio…

General Issues in Small-x and Diffractive Physics

A. H. Mueller

A selected review of topics at the border of hard and soft physics is given. Particular emphasis is a placed on diffraction dissociation at Fermilab and HERA. Recently, significant…

Galactic Halo Models and Particle Dark-Matter Detection

Marc Kamionkowski, Ali Kinkhabwala

Rates for detection of weakly-interacting massive-particle (WIMP) dark matter are usually carried out assuming the Milky Way halo is an isothermal sphere. However, it is possible t…

Quantum Effects on Higgs Winding Configurations

Arthur Lue

We examine the quantum corrections to the static energy for Higgs winding configurations. We evaluate the effective action for such configurations in Weinberg-Salam theory without…

Isolated Prompt Photon Production

Edmond L. Berger, Xiaofeng Guo, Jianwei Qiu

We show that the conventionally defined partonic cross section for the production of isolated prompt photons is not an infrared safe quantity. We work out the case of $e^+e^- \to γ…

Analytic Solution of the Pion-Laser Model

T. Csorgo, J. Zimanyi

Brooding over bosons, wave packets and Bose - Einstein correlations, we find that a generalization of the pion-laser model for the case of overlapping wave-packets is analytically…

Higher Order Bose-Einstein Correlations for Systems with Large Halo

T. Csorgo

A generalization of the core/halo model to the Bose-Einstein correlation function of any number of particles is presented. In particular, a simple prediction is obtained for the in…

Leading Baryons at Low x_L in DIS and Photoproduction at ZEUS

Nicolò Cartiglia

Results obtained by the ZEUS collaboration on leading baryon production in the proton fragmentation region are presented. The reaction , with N a proton or a neutron, i…

Structure Function Subgroup Summary

D. Harris, F. I. Olness, S. Ritz +30

We summarize the studies and discussions of the Structure Function subgroup of the QCD working group of the Snowmass 1996 Workshop: New Directions for High Energy Physics.

Inflaton Decay and Heavy Particle Production with Negative Coupling

Brian R. Greene, Tomislav Prokopec, Thomas G. Roos

We study the decay of the inflaton in a renormalizable two scalar theory. Since the dynamics of the system is dominated by states with large occupation numbers which admit a semicl…

Non-Forward and Unequal Mass Virtual Compton Scattering

Zhang Chen

We discuss the general operator product expansion of a non-forward unequal mass virtual compton scattering scattering amplitude. We find that the expansion now should be done in do…

Unitarity Corrections and High Field Strengths in High Energy Hard Collisions

Yuri V. Kovchegov, A. H. Mueller, Samuel Wallon

Unitarity corrections to the BFKL description of high energy hard scattering are viewed in large QCD in light-cone quantization. In a center of mass frame unitarity correctio…

Classical Gluon Radiation in Ultrarelativistic Nucleus-Nucleus Collisions

Yuri V. Kovchegov, Dirk H. Rischke

The classical Yang-Mills equations are solved perturbatively in covariant gauge for a collision of two ultrarelativistic nuclei. The nuclei are taken as ensembles of classical colo…

Diffraction at HERA

Nicolò Cartiglia

Recent results on diffraction at HERA, as measured by the H1 and ZEUS collaborations, are reviewed. Results on the photon-proton total hadronic cross section, on vector meson produ…

Quantum structure of the non-Abelian Weizsacker-Williams field for a very large nucleus

Yuri V. Kovchegov

We consider the McLerran-Venugopalan model for calculation of the small- part of the gluon distribution function for a very large ultrarelativistic nucleus at weak coupling. We…
