LHC的NLO事件样本

NLO event samples for the LHC

M. V. Garzelli, Adam Kardos, Zoltán Trócsányi

摘要:

我们介绍了一个twiki页面,收集了在LHC能量下质子-质子碰撞中产生的Monte Carlo事件样本,包括最终状态的重夸克-反夸克对。这些样品是用POWHEG方法产生的,可以用来制备NLO精度的分布,第一次辐射根据部分子簇射方法处理。与每项活动有关的资料以《莱苏什协定》规定的格式储存。标准的部分子簇射蒙特卡罗程序可以用来进一步演化这些事件,并在强子水平上模拟事件,为几乎任意的实验分析做好准备。当前可用的最终状态如下:(i)t + \bar{t},(ii)t + \bar{t} + H,(iii)t + \bar{t} +喷流,同时几个其它最终状态的生成正在进行中。

英文摘要:

We introduce a twiki page with collections of generated Monte Carlo event samples in proton-proton collisions at LHC energies including a heavy quark-antiquark pair in the final state. These samples are generated with the POWHEG method and can be used to prepare distributions at the NLO accuracy with first radiation treated according to the parton shower approach. Information related to each event is stored in the form prescribed by the Les Houches Accords. Standard parton shower Monte Carlo programs can be used to further evolve these events, and simulate events at the hadron level, ready for almost arbitrary experimental analysis. Currently the available final states are the following: (i) t + \bar{t}, (ii) t + \bar{t} + H, (iii) t + \bar{t} + jet, while the generation of several other final states is in progress.
