RT Journal Article T1 Reggeon field theory for large Pomeron loops A1 Altinoluk, Tolga A1 Kovner, Alex A1 Levin, Eugene A1 Lublinsky, Michael K1 Resummation K1 QCD K1 Deep inelastic scattering AB We analyze the range of applicability of the high energy Reggeon Field TheoryHRFT derived in [1]. We show that this theory is valid as long as at any intermediatevalue of rapidity η throughout the evolution at least one of the colliding objects is dilute.Importantly, at some values of η the dilute object could be the projectile, while at othersit could be the target, so that HRFT does not reduce to either HJIMWLK or HKLWMIJ .When both objects are dense, corrections to the evolution not accounted for in [1] becomeimportant. The same limitation applies to other approaches to high energy evolutionavailable today, such as for example [2, 3] and [4–6]. We also show that, in its regimeof applicability HRFT can be simplified. We derive the simpler version of HRFT and inthe large Nc limit rewrite it in terms of the Reggeon creation and annihilation operators.The resulting HRFT is explicitly self dual and provides the generalization of the Pomeroncalculus developed in [4–6] by including higher Reggeons in the evolution. It is applicablefor description of ‘large’ Pomeron loops, namely Reggeon graphs where all the splittingsoccur close in rapidity to one dilute object (projectile), while all the merging close to theother one (target). Additionally we derive, in the same regime expressions for single anddouble inclusive gluon production (where the gluons are not separated by a large rapidityinterval) in terms of the Reggeon degrees of freedom PB Springer SN 1029-8479 YR 2014 FD 2014 LK http://hdl.handle.net/10347/21450 UL http://hdl.handle.net/10347/21450 LA eng NO Altinoluk, T., Kovner, A., Levin, E. et al.
