The Standard Model of Particle Physics

Mary K. Gaillard, Paul D. Grannis, Frank J. Sciulli

Particle physics has evolved a coherent model that characterizes forces and particles at the most elementary level. This Standard Model, built from many theoretical and experimenta…

Gluon mini-jet production in nuclear collisions at high energies

Xiaofeng Guo

We show explicitly that the leading soft gluon distribution, predicted by Kovner, McLerran, and Weigert after solving classical Yang-Mills equations, can be understood in ter…

Bose-Einstein Correlations in a Space-Time Approach to e+ e- Annihilation into Hadrons

K. Geiger, J. Ellis, U. Heinz +1

A new treatment of Bose-Einstein correlations is incorporated in a space-time parton-shower model for e+ e- annihilation into hadrons. Two alternative afterburners are discussed, a…

Signatures of Quark-Gluon-Plasma formation in high energy heavy-ion collisions: A critical review

S. A. Bass, M. Gyulassy, H. Stoecker +1

A critical review on signatures of Quark-Gluon-Plasma formation is given and the current (1998) experimental status is discussed. After giving an introduction to the properties of…

Strange hyperon and antihyperon production from quark and string-rope matter

P. Csizmadia, P. Levai, S. E. Vance T. S. Biro +2

Hyperon and antihyperon production is investigated using two microscopical models: {\bf (1)} the fast hadronization of quark matter as given by the ALCOR model; {\bf (2)} string fo…

High p_T Phenomena in Heavy Ion Collisions at s^1/2=20 and 200 AGeV

Miklos Gyulassy, Peter Levai

Jet quenching as observed via high p_T hadron production is studied in the HIJING1.35 model. We test the model on recent WA98 data on 160 AGeV Pb+Pb -> pi0 up to 4 GeV/c. The resul…

Transverse momentum broadening due to the multiple scattering

Xiaofeng Guo

Using the Drell-Yan process in hadron-nucleus collisions and deeply inelastic lepton-nucleus scattering (DIS) as examples, I show that the transverse momentum broadening can be exp…

Jet Quenching and Cronin Enhancement in A+A at s^1/2=20 vs 200 AGeV

Miklos Gyulassy, Peter Levai

The sensitivity of semi-hard (p_\perp < 10 GeV) hadron production to parton energy loss in high energy nuclear collisions is studied via the HIJING1.35 model. We test the model on…

Running Coupling Effects in BFKL Evolution

Yuri V. Kovchegov, A. H. Mueller

We resum the recently calculated second order kernel of the BFKL equation. That kernel can be viewed as the sum of a conformally invariant part and a running coupling part. The con…

Three-Body Annihilation of Neutralinos Below Two-Body Thresholds

Xuelei Chen, Marc Kamionkowski

We calculate the cross section for s-wave neutralino annihilation to three-body final states below the W^+ W^- and t-bar t thresholds. Such three-body channels may dominate the ann…

Jet broadening in deeply inelastic scattering

Xiaofeng Guo

In deeply inelastic lepton-nucleus scattering (DIS), the average jet transverse momentum is broadened because of the multiple scattering in the nuclear medium. The size of jet broa…

Medium-induced radiative energy loss; equivalence between the BDMPS and Zakharov formalisms

R. Baier, Yu. L. Dokshitzer, A. H. Mueller +1

We extend the BDMPS formalism for calculating radiative energy loss to the case when the radiated gluon carries a finite fraction of the quark momentum. Some virtual terms, previou…

Radiative Energy Loss of High Energy Partons Traversing an Expanding QCD Plasma

R. Baier, Yu. L. Dokshitzer, A. H. Mueller +1

We study analytically the medium-induced energy loss of a high energy parton passing through a finite size QCD plasma, which is expanding longitudinally according to Bjorken's mode…

Gluon production in current-nucleus and nucleon-nucleus collisions in a quasi-classical approximation

Yuri V. Kovchegov, A. H. Mueller

We calculate gluon production in deep inelastic scattering of the current j= - (1/4) F_{μν}^a F_{μν}^a off a large nucleus and in nucleon-nucleus collisions. In a covariant gauge c…

CP Violation from Surface Terms in the Electroweak Theory without Fermions

Arthur Lue, Mark Trodden

We consider the effect of adding a CP-odd, theta FFdual-term to the electroweak Lagrangian without fermions. This term affects neither the classical nor perturbatively quantum phys…

Nuclear Dependence in Transverse Momentum Distribution for Drell-Yan Pair

Xiaofeng Guo

In terms of multiple scattering picture, I compute the nuclear dependence in Drell-Yan transverse momentum distribution, , in hadron-nucleus collisions. I present…
