标题： Diphoton Production at Hadron Colliders and New Contact Interactions

摘要： 我们探讨了质子对撞机和大型强子对撞机在限制可能存在的无味依赖的$q \bar q \gamma\gamma$接触相互作用方面的能力，这种相互作用可能导致大量具有大不变质量的双光子事件。 假设没有观察到与标准模型的偏离，我们表明质子对撞机最终能够对该新接触相互作用相关的尺度设定一个下限，为0.5-0.6 TeV。 在大型强子对撞机上，通过适当的探测器截断和积分亮度为$100 fb^{-1}$，可能探测到高达3-6 TeV的尺度。 显示英文摘要

摘要： We explore the capability of the Tevatron and LHC to place limits on the possible existence of flavor-independent $q \bar q \gamma\gamma$ contact interactions which can lead to an excess of diphoton events with large invariant masses. Assuming no departure from the Standard Model is observed, we show that the Tevatron will eventually be able to place a lower bound of 0.5-0.6 TeV on the scale associated with this new contact interaction. At the LHC, scales as large as 3-6 TeV may be probed with suitable detector cuts and an integrated luminosity of $100 fb^{-1}$.
