Abstract:
The central exclusive production of the pseudoscalar and axial vector mesons 0 and f1 is studied in peripheral proton collisions. This process is considered in the Regge limit, i.e. high energy limit with small transverse momentum transfer, which is thought to predominantly produce glueball intermediate states. These intermediate states will be parametrized using Pomeron trajectories. On the one hand vertices and propagators from the Witten-Sakai- Sugimoto model, which is a top-down holographic approach to low-energy Quantum Chromodynamics, is used. On the other hand the Tensor-Pomeron model is used, which is an effective field theory guided by gauge principles and covariance. A comparision of these models is made based on experimental results from the WA102 collaboration.
