Holographic Double Diffractive Scattering
, 806
"... Abstract: The holographic description of Pomeron exchange in a strongly-coupled gauge theory with an AdS dual is extended to the case of two to three scattering. We study the production event of a central particle via hadron-hadron scattering in the double Regge kinematic regime of large center-of-m ..."

Real and Virtual Compton Scattering in a Regge Approach
, 2003
"... We study Real and Deeply Virtual Compton Scattering in a model based on Regge trajectories and two-gluon exchange. In the kinematic regime of current experiments, the hadronic component of the outgoing real photon plays a major role. We analyze the spin structure of Compton scattering at large momen ..."

GLUON PAIR PRODUCTION IN THE QUASI-MULTI-REGGE KINEMATICS ∗
, 1996
"... To find the region of applicability of the leading log(1/x) approximation for parton distributions in the small x region and to fix the argument of the QCD running coupling it is necessary to know radiative corrections to the kernel of the BFKL equation. The next-to-leading corrections to the BFKL k ..."

kernel are expressed in terms of the two-loop correction to the gluon Regge trajectory, one-loop correction to the Reggeon-Reggeon-gluon vertex, and contributions from two-gluon and quarkantiquark production in the quasi-multi-Regge kinematics. We calculate differential and total cross sections
The perturbative Regge-calculus regime of loop quantum gravity
- Nuclear Physics B 796 [FS] (2008) 581–621. BOJAN MOHAR AND IGOR RIVIN
"... The relation between Loop Quantum Gravity and Regge calculus has been pointed out many times in the literature. In particular the large spin asymptotics of the Barrett-Crane vertex amplitude is known to be related to the Regge action. In this paper we study a semiclassical regime of Loop Quantum Gra ..."

Semiclassical regime of Regge calculus and spin foams
, 2008
"... Recent attempts to recover the graviton propagator from spin foam models involve the use of a boundary quantum state peaked on a classical geometry. The question arises whether beyond the case of a single simplex this suffices for peaking the interior geometry in a semiclassical configuration. In th ..."

in an asymptotic expansion. Further, we show that if we replace at each simplex the exponential of the Regge action by its cosine – as expected from the semiclassical limit of spin foam models – then the contribution from the sign-reversed terms is suppressed in the semiclassical regime and the results match those
Exponential fall-off behavior of Regge scatterings in compactified open string theory
"... We calculate massive string scattering amplitudes of compactified open string in the Regge regime. We extract the complete infinite ratios among high-energy amplitudes of different string states in the fixed angle regime from these Regge string scattering amplitudes. The complete ratios calculated b ..."

, arXiv:1012.5225] to link fixed angle and Regge string scattering amplitudes. In addition, we discover a kinematic regime with stringy highly winding modes, which shows the unusual exponential fall-off behavior in the Regge string scattering. This is complimentary with a kinematic regime discovered
Degeneracy Between the Regge Slope of
, 901
"... We consider the degeneracy between the Regge slope of mesons and baryons in QCD. We argue that within the “orientifold large-N approximation ” asymptotically massive mesons and baryons become supersymmetric partners and hence degenerate. To this end, we generalize QCD by a SU(N) theory with a quark ..."
