用ATLAS探测器测量在TeV的pp碰撞中具有附加中心喷流活动否决权的双喷流产生

Measurement of dijet production with a veto on additional central jet activity in pp collisions at 7 TeV using the ATLAS detector

P. Bernat

摘要:

喷流活动的测量范围内的快速性间隔的dijet系统进行使用PP碰撞在7 TeV的ATLAS探测器在2010年记录。将数据与PYTHIA、HERWIG++和ALPGEN事件发生器的LO预测进行比较。这些数据还比较了从POWHEG的NLO部分子簇射预测,当接口到PYTHIA或HERWIG部分子簇射,和所有的订单重申从HEJ的预测。在大多数的相空间区域,实验的不确定性是远远小于传播的LO蒙特卡罗事件发生器的预测。一般来说,POWHEG+PYTHIA给出了数据的最佳描述。

英文摘要:

A measurement of jet activity in the rapidity interval bounded by a dijet system is performed using pp collisions at 7 TeV recorded by the ATLAS detector in 2010. The data are compared to LO predictions from PYTHIA, HERWIG++ and ALPGEN event generators. The data are also compared to NLO parton shower prediction from POWHEG, when interfaced to PYTHIA or HERWIG parton shower, and all order resummation prediction from HEJ. In most of the phase-space regions presented, the experimental uncertainty is much smaller than the spread of LO Monte Carlo event generator predictions. In general, POWHEG+PYTHIA gave the best description of the data.
