在大型强子对撞机上,多部分子相互作用将代表最小偏差和潜在事件的一个重要特征,并将在寻找新物理学的许多感兴趣的渠道中做出重要贡献。不同数量的多重碰撞可能有助于产生一个给定的最终状态,人们应该期待在不同的贡献有类似的速率的制度中的重要的干扰效应。相反,我们表明,一旦多个部分子相互作用被确定其不同的拓扑结构,具有不同数量的多个部分子相互作用的条款不干扰最终的横截面。
At the LHC multiple parton interactions will represent an important feature of the minimum bias and of the underlying event, and will give important contributions in many channels of interest in the search for new physics. Different numbers of multiple collisions may contribute to the production of a given final state, and one should expect important interference effects in the regime where different contributions have similar rates. We show, on the contrary, that, once multiple parton interactions are identified by their different topologies, terms with different numbers of multiple parton interactions do not interfere in the final cross section.
