The quark part of the non-forward BFKL kernel and the "bootstrap" for the gluon Reggeization

We calculate the quark part of the kernel of the generalized non-forward BFKL equation at non-zero momentum transfer

in the next-to-leading logarithmic approximation. Along with the quark contribution to the gluon Regge trajectory, this part includes pieces coming from the quark-antiquark production and from the quark contribution to the radiative corrections in one-gluon production in the Reggeon-Reggeon collisions. The results obtained can be used for an arbitrary representation of the colour group in the

The condition is fulfilled in the general case of an arbitrary space-time dimension and massive quark flavors for both helicity conserving and non-conserving parts.

A Deeply Virtual Compton Scattering Amplitude

Abstract The dipole (Mobius) representation of the colour singlet BFKL kernel in the next-to-leading order is found in supersymmetric Yang–Mills theories. Ambiguities of this form and its conformal properties are discussed.

Spectrum of screening masses nearTc:Predictions from universality

We calculate in the next-to-leading approximation the non-forward quark impact factors for both singlet and octet color representation in the
