BFKL Pomeron: Modeling confinement

Research output: Contribution to journalArticlepeer-review

Abstract

In this talk we introduce the confinement into the kernel of the BFKL equation, assuming that the sizes of produced dipoles cannot be large. The goal of this talk is to share with you our study how this assumption, which leads to a correct exponential decrease of the amplitude at large impact parameters, affects the main properties of the BFKL Pomeron. We solve the equations for total cross section and 〈|b2|〉 numerically and developed some methods of analytical solutions. The main result is that the modified BFKL Pomeron has the same intercept and αP'=0 as the BFKL Pomeron. It gives us a hope that the unknown confinement will change only slightly the equations of the CGC/saturation approach.
