It is shown that the colour dipole approach to hard scattering at high energy is fully compatible with k_T factorization at the leading logarithm approximation (in -log x_Bj). The relations between the dipole amplitudes and unintegrated diagonal and

To study diffractive photon production at HERA, we compute the projection of the \(\gamma^*\gamma\) impact-factor on the BFKL leading-order eigenfunctions \(E^{n,\nu}\) for non-zero transfer. This calculation supplements former ones performed for n =

Using the QCD dipole picture of BFKL dynamics, the quasi elastic component of the diffractive gamma*-dipole cross-section, dominating at small M^2/Q^2, is calculated.

Using the recent solution of the triple Pomeron coupling in the QCD dipole picture as a closed string amplitude with six legs, its analytical form in terms of hypergeometric functions and numerical value are derived.

The conformal invariance properties of the QCD Pomeron in the transverse plane allow us to give an explicit analytical expression for the solution of the BFKL equations both in the transverse coordinate and momentum spaces. This result is obtained fr

The regulated propagator G’e(ξ,ξ’) is considered for points ξ and ξ’ on the two‐dimensional flat torus and with a regularization analogous to the proper‐time method with cut‐off e. The inequivalent tori are labeled by a modular parame

After the pionnering work of Schwinger in the ’40s for potential scattering, the most elaborate and widely used radiative correction procedure for electro-magnetic scattering on hadronic targets remains that given in the ’60s by Y. S. Tsai1) for

This paper studies the divergences of the bosonic string coupled to background fields, the graviton, the dilaton and the tachyon fields. These divergences are computed to first order in the string tension parameter for the topologies of the sphere an

We show that, in onium-onium scattering at (very) high energy, a transition to saturation happens due to quantum fluctuations of QCD dipoles. This transition starts when the order $\alpha^2$ correction of the dipole loop is compensated by its faster
