Gabor I. Veres, CMS Collaboration

摘要:

本文测量了sqrt(s)=0.9和2.36TeV质子-质子碰撞中包含的带电强子横动量(pT)和赝快度(eta)分布。对于非单衍射相互作用,带电强子的平均pT被测量为0.46 ± 0.01(stat.)± 0.01(stat.)0.01(系统)GeV/c at 0.9 TeV and 0.50+-0.01(stat.)+- 0.01(系统)对于|eta| <2.4,在2.36 TeV下的GeV/c。在这些能量下,在中心区域测得的赝快度密度dNch/deta(|eta| <0.5)为3.48 ± 0.02(stat.)± 0.05。0.13(系统)和4.47+-0.04(统计)+- 0.16(系统),分别2.36 TeV的结果代表了在路易斯湖冬季研究所发表的粒子对撞机上发表的最高能量测量结果。

英文摘要:

Measurements of inclusive charged-hadron transverse-momentum (pT) and pseudorapidity (eta) distributions are presented for proton-proton collisions at sqrt(s)=0.9 and 2.36 TeV. For non-single-diffractive interactions, the average pT of charged hadrons is measured to be 0.46+-0.01(stat.)+-0.01(syst.) GeV/c at 0.9 TeV and 0.50+-0.01(stat.)+-0.01(syst.) GeV/c at 2.36 TeV, for |eta|<2.4. At these energies, the measured pseudorapidity densities in the central region, dNch/deta(|eta|<0.5), are 3.48+-0.02(stat.)+-0.13(syst.) and 4.47+-0.04(stat.)+-0.16(syst.), respectively. The results at 2.36 TeV represent the highest-energy measurements ever published at a particle collider at the time of the presentation at the Lake Louise Winter Institute.
