The system of four reggeized gluons and the three-pomeron vertex in the high colour limit
The amplitude for 4 interacting reggeized gluons is studied in the high-colour limit. The leading order amplitude is explicitly shown to reduce to a pair of reggeons, i.e to a single BFKL pomeron. The next-to-leading order diffractive amplitude is found to split into a double pomeron exchange and triple pomeron contribution. The obtained three-pomeron vertex is different from the originally pro...
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...
متن کاملThe Pomeron beyond Bfkl
Conformally invariant reggeon interactions derived from t-channel unitarity are discussed and progress towards understanding the “physical Pomeron”, via massless quark reggeon interactions, is briefly outlined. Presented at the 5th International Workshop on Deep Inelastic Scattering and QCD, Chicago, Illinois, USA, April 14-18, 1997 Work supported by the U.S. Department of Energy, Division of H...
متن کاملThe bootstrap condition for many reggeized gluons and the photon structure function at low x and N c → ∞
The bootstrap condition for many reggeized gluons and the photon structure function at low x and Abstract. The bootstrap condition is generalized to n reggeized gluons. As a result it is demonstrated that the intercept generated by n reggeized gluons cannot be lower than the one for n = 2. Arguments are presented that in the limit N c → ∞ the bootstrap condition reduces the n gluon chain with i...
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) ...
