Pomeron 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 کاملAn 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 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 کاملThe Pomeron and Gauge/String Duality
The traditional description of high-energy small-angle scattering in QCD has two components — a soft Pomeron Regge pole for the tensor glueball, and a hard BFKL Pomeron in leading order at weak coupling. On the basis of gauge/string duality, we present a coherent treatment of the Pomeron. In large-N QCD-like theories, we use curved-space string-theory to describe simultaneously both the BFKL re...
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.
