The γ∗γ∗ total cross section and the BFKL Pomeron at e+e− colliders

Abstract We present a numerical estimate of the γ ∗ γ ∗ total cross section at LEP and at the designed e+ e− Next Linear Collider (NLC), based upon the BFKL Pomeron. We find for the linear collider that the event rate is substantial provided electrons scattered under small angles can be detected, and a measurement of this cross section provides an excellent test of the BFKL Pomeron. For LEP, although the number of events is substantially smaller, an initial study of this process is feasible.

Quark-antiquark production in DIS diffractive dissociation

Abstract We calculate the cross section for the production of two jets with large transverse momenta k2 in DIS diffractive dissociation for both transverse and longitudinally polarized photons. The scale which defines the hardness of the pomeron is found to be k 2 Q 2 +M 2 M 2 M . We present analytic expressions and discuss numerical results relevant for the diffractive dissociation at HERA.We calculate the cross section for the production of two jets with large transverse momenta

A numerical estimate of the small-kT region in the BFKL pomeron☆

Abstract The cross section for elastic vector meson production in photon-proton interactions at large t is considered using the exact analytic solution of the BFKL equation in the azimuthally symmetric n = 0 limit. We use a non-relativistic model for the vector meson production and find a small shrinkage in the t -distribution with increasing energy.The cross section for elastic vector meson production in photon-proton interactions at large
