论文摘要
我们介绍了质子 - 蛋白质碰撞中光子引发的生产的新型Superchic 4 Monte Carlo实施的结果，这是Lepton对生产的第一个例子。这是基于基础过程的结构函数计算，并重点介绍了各种贡献通道的完整说明，包括施加速度差距否决的情况。我们对贡献进行了仔细的处理，即（单个解离），无论是（双重解离）还是（弹性）质子都不相互作用和分离，并将我们的结果与潮汐仪进行淋浴和强春化。分离系统中的粒子衰减分布以及没有其他质子 - 蛋白质相互作用的生存概率都充分考虑了；这些对于与应用速度差距否决的数据进行比较至关重要。我们介绍了否决权对差异横截面的影响，与Atlas 7 TEV数据进行比较并找到了关于半独占生产的数据并良好一致的结果，并提供了对SUSY Lepton Pair生产到SUSY粒度生产到压缩质量场景中的SUSY粒子生产的新的精确评估，这是较低的。
We present the results of the new SuperChic 4 Monte Carlo implementation of photon-initiated production in proton-proton collisions, considering as a first example the case of lepton pair production. This is based on the structure function calculation of the underlying process, and focusses on a complete account of the various contributing channels, including the case where a rapidity gap veto is imposed. We provide a careful treatment of the contributions where either (single dissociation), both (double dissociation) or neither (elastic) proton interacts inelastically and dissociates, and interface our results to Pythia for showering and hadronization. The particle decay distribution from dissociation system, as well the survival probability for no additional proton-proton interactions, are both fully accounted for; these are essential for comparing to data where a rapidity gap veto is applied. We present detailed results for the impact of the veto requirement on the differential cross section, compare to and find good agreement with ATLAS 7 TeV data on semi-exclusive production, and provide a new precise evaluation of the background from semi-exclusive lepton pair production to SUSY particle production in compressed mass scenarios, which is found to be low.
