Conformal intercept of BFKL pomeron with NLO running coupling constant corrections
In the present note we propose a shift of the anomalous dimension function of the eigenfunctions of the BFKL equation with the NLO running coupling corrections. The calculated eigenvalue of the modified equation turns out to be conformal invariant and we discuss consequences of this result.
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 کاملRunning coupling and BFKL pomeron
PACS numbers: 12.38 Cy One of the major issues in the high energy limit of QCD is the problem of interplay between the perturbative and non-perturbative regimes. The BFKL Pomeron in the leading logarithmic approximation [1] results in the equation which exhibits the characteristic diffusion pattern [2]. In the process with two, comparable hard scales (for example γ−γ, or forward jet/π0 in DIS) ...
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 کاملReggeized Gluons with a Running Coupling Constant
The equation for two reggeized gluons in the vacuum channel is generalized to take into account the running QCD coupling constant on the basis of the bootstrap condition for gluon reggeization. Both the gluon trajectory as a function of momentum and the interaction as a function of distance grow like log log in the ultraviolet. The resulting equation depends on the confinement region. With a si...
