摘要:

高能质子-(反)质子碰撞的中心独占产生(CEP)过程为研究QCD的新方面和新的物理信号提供了一个非常有前途的框架。在可以用这种方式研究的许多有趣的过程中,那些涉及产生重(c,b)夸克偶素和伽马伽马态的过程具有足够好的理论性质和足够大的截面,它们可以作为“标准烛光”过程,我们可以用它来基准预测欧洲核子研究中心大型强子对撞机的新物理CEP。最近CEP测量在费米实验室Tevatron的理论预测的广泛协议的动机,我们进行了详细的定量研究的重夸克偶素(chi和eta)和伽马-伽马生产的Tevatron,RHIC和LHC,特别注意在计算中的各种不确定性。我们的研究结果证实了丰富的现象,这些生产过程提供了目前和未来的高能对撞机。

英文摘要:

Central exclusive production (CEP) processes in high-energy proton -- (anti)proton collisions offer a very promising framework within which to study both novel aspects of QCD and new physics signals. Among the many interesting processes that can be studied in this way, those involving the production of heavy (c,b) quarkonia and gamma gamma states have sufficiently well understood theoretical properties and sufficiently large cross sections that they can serve as `standard candle' processes with which we can benchmark predictions for new physics CEP at the CERN Large Hadron Collider. Motivated by the broad agreement with theoretical predictions of recent CEP measurements at the Fermilab Tevatron, we perform a detailed quantitative study of heavy quarkonia (chi and eta) and gamma gamma production at the Tevatron, RHIC and LHC, paying particular attention to the various uncertainties in the calculations. Our results confirm the rich phenomenology that these production processes offer at present and future high-energy colliders.
