Photon impact factor in the next-to-leading order
Ian Balitsky, Giovanni A. Chirilli
An analytic coordinate-space expression for the next-to-leading order photon impact factor for small- deep inelastic scattering is calculated using the operator expansion in Wil…
High-energy amplitudes and impact factors at next-to-leading order
Giovanni Antonio Chirilli
To study scattering amplitudes at high-energy, the T-product of two currents can be expanded in terms of coefficient functions (impact factors) and matrix elements of ``composite c…
NLO evolution of color dipoles in N=4 SYM
Ian Balitsky, Giovanni A. Chirilli
High-energy behavior of amplitudes in a gauge theory can be reformulated in terms of the evolution of Wilson-line operators. In the leading logarithmic approximation it is given by…
Conformal kernel for NLO BFKL equation in =4 SYM
Ian Balitsky, Giovanni A. Chirilli
Using the requirement of Möbius invariance of =4 SYM amplitudes in the Regge limit we restore the conformal NLO BFKL kernel out of the eigenvalues known from the forward…
