An analysis on extrema and constrained bounds for the soft Pomeron intercept
We investigate some aspects and consequences of the extrema bounds for the soft Pomeron intercept, recently determined by means of global fits to pp and p̄p total cross section data at both accelerator and cosmic-ray energy regions (scattering data). We also examine the effects of the secondary Reggeons by introducing fitted trajectories from Chew-Frautschi plots (spectroscopy data) and determin...
متن کاملPomeron intercept and slope: the QCD connection
The ratio of intercept to slope of the Pomeron trajectory is derived in a phenomenological model based on a QCD approach to diffraction.
متن کاملSoft Pomeron Physics on the Lattice
We use lattice QCD to investigate some topics in strong interaction phenomenol-ogy which are usually related to soft pomeron exchange. These include hadronic cross-sections at high energies and diffractive scattering at HERA. Some numerical results are presented in the framework of the Landshoff-Nachtmann pomeron model, and strategies for further studies are discussed.
متن کاملFROM BLACK HOLES TO POMERON: Tensor Glueball and Pomeron Intercept at Strong Coupling
We briefly review the approach for strong coupling calculation of glueball masses based on the duality between supergravity and Yang-Mills theory. Earlier work is extended to non-zero spin. Fluctuations in the gravitational metric lead to the 2 tensor glueball state on the leading Pomeron trajectory with a mass relation: m(0) < m(2). In particular, for QCD4, a strong coupling expansion for the ...
متن کاملDamtp 96/48 the Soft Pomeron
The soft pomeron successfully correlates a wide variety of data. Its properties seem rather simple: it couples to single quarks and its coupling factorises.
