彩色玻璃凝聚体中LHC处pA相互作用的带电粒子多重性

Charged particle multiplicities in pA interactions at the LHC from the Color Glass Condensate

Amir H. Rezaeian

摘要:

即将进行的质子-核碰撞强子多重数的LHC测量是对基于k_t因子分解和胶子饱和模型的重要检验。在这里,我们提供了定量预测的带电粒子的赝快度分布的最小偏压质子-核碰撞在LHC的胶子饱和的想法的基础上的颜色玻璃凝聚框架。我们的公式给出了很好的描述的LHC和RHIC数据的带电强子多重性在质子-质子和核-核碰撞,也深非弹性散射在HERA在小Bjorken-x。

英文摘要:

The forthcoming LHC measurement of hadron multiplicity in proton-nucleus collisions is a crucial test of the k_t factorization and gluon saturation based models. Here, we provide quantitative predictions for the pseudorapidity distribution of charged particles produced in minimum bias proton-nucleus collisions at the LHC based on the idea of gluon saturation in the color-glass condensate framework. Our formulation gives good descriptions of the LHC and RHIC data for the charged-hadron multiplicities in both proton-proton and nucleus-nucleus collisions, and also the deep inelastic scattering at HERA at small Bjorken-x.
