LHC能区高p_T下的粒子比

Particle Ratios at High p_T at LHC Energies

G. G. Barnafoldi, P. Levai, B. A. Cole, G. Fai, G. Papp

摘要:

用pQCD改进的部分子模型计算了pp、dA和重离子碰撞中的强子产生。我们应用了KKP和AKK片段化函数。我们的喷注碎裂研究表明,在高p_T下强子比主要取决于夸克的贡献,而较少取决于胶子的贡献。这一发现也可以在射流能量损失计算中看到。我们展示了LHC能区PbPb碰撞中不同强子比的抑制图象。

英文摘要:

Hadron production has been calculated in a pQCD improved parton model for pp, dA and heavy ion collisions. We applied KKP and AKK fragmentation functions. Our jet fragmentation study shows, that hadron ratios at high p_T depend on quark contribution mostly and less on the gluonic one. This finding can be seen in jet-energy loss calculations, also. We display the suppression pattern on different hadron ratios in PbPb collisions at LHC energies.
