论文摘要
在这封信中，我们估算了大型强子对撞机（LHC）中$ pp $碰撞的双衍射过程的双衍射过程的贡献。考虑了中央和正向LHC检测器的接受，并提出了不变质量，速度和横向动量分布的预测。进行了与光的预测 - 通过 - 光（LBL）散射和独家二光子产生的比较。我们证明，与双重衍射过程相关的事件可以分开，并且可以使用其研究来限制衍射Parton分布函数的行为。
In this letter we estimate the contribution of the double diffractive processes for the diphoton production in $pp$ collisions at the Large Hadron Collider (LHC). The acceptance of the central and forward LHC detectors is taken into account and predictions for the invariant mass, rapidity and, transverse momentum distributions are presented. A comparison with the predictions for the Light -- by -- Light (LbL) scattering and exclusive diphoton production is performed. We demonstrate that the events associated to double diffractive processes can be separated and its study can be used to constrain the behavior of the diffractive parton distribution functions.
