Central exclusive photoproduction at the LHC

A. Cisek, W. Schäfer, A. Szczurek

摘要:

质子和反质子在对撞机的能量是一个来源的高能量Weizsaecker-Williams光子。这为在大型强子对撞机上研究重矢量介子的光生提供了可能性,其能量要比在HERA加速器上大得多。我们提出了我们的详细研究的各种分布的重夸克偶素的生产(例如,快度,横动量,方位角)的选择结果。我们预测LHC的能量。我们的计算是基于模拟的光产生振幅的k_ \perp -因子分解的方法,这是检查对HERA数据。我们还讨论了光生Z^0玻色子的唯一性。

英文摘要:

Protons and antiprotons at collider energies are a source of high energy Weizsaecker--Williams photons. This opens up a possibility to study at the LHC exclusive photoproduction of heavy vector mesons at energies much larger than possible at the HERA accelerator. We present selected results of our detailed studies of various distributions for the production of heavy quarkonia (e.g. rapidity, transverse momenta, azimuthal angles). We give predictions for LHC energies. Our calculations are based on modelling the photoproduction amplitudes in a k_\perp-factorisation approach which is checked against HERA data. We also discuss the exclusive photoproduction of Z^0 bosons.
