Physical Review Letters 2024年 第25期132卷 251901-251901页
作者: Leonardo Bonino Thomas Gehrmann Giovanni Stagnitto & INFN Piazza della Scienza 3 20216 Milano Italy
Semi-inclusive hadron production processes in deep-inelastic lepton-nucleon scattering are important probes of the quark flavor structure of the nucleon and of the fragmentation dynamics of quarks into hadrons. We com... 详细信息

Physical Review C 2008年 第3期78卷 034908-034908页
作者: Thorsten Renk []Department of Physics University of Jyv?skyl? P. O. Box 35 FI-40014 Finland and Helsinki Institute of Physics University of Helsinki P. O. Box 64 FI-00014 Finland
We present a Monte Carlo simulation of the perturbative quantum chromodynamics shower developing after a hard process embedded in a heavy-ion collision. The main assumption is that the cascade of branching partons tra... 详细信息

Physical Review C 2007年 第6期76卷 065209-065209页
作者: Gerald A. Miller University of Washington Seattle Washington 98195-1560 USA
Spin-dependent quark densities, matrix elements of specific density operators in proton states of definite spin-polarization, indicate that the nucleon may harbor an infinite variety of nonspherical shapes. We show th... 详细信息

Physical Review C 2004年 第5期70卷 054902-054902页
作者: Rudolph C. Hwa C. B. Yang Institute of Theoretical Science and Department of Physics University of Oregon Eugene Oregon 97403-5203 USA Institute of Particle Physics Hua-Zhong Normal University Wuhan 430079 China
The difference between the structures of jets produced in heavy-ion and hadronic collisions can best be exhibited in the correlations between particles within those jets. We study the dihadron correlations in jets in ... 详细信息

Physical Review C 2007年 第3期76卷 034902-034902页
作者: A. Accardi Department of Physics and Astronomy Iowa State University Ames Iowa 50011 USA
I examine the role of final state interactions in cold nuclear matter in modifying hadron production on nuclear targets with leptonic or hadronic beams. I demonstrate the extent to which available experimental data in... 详细信息
