Summing pomeron trees

Summing Pomeron loops in the dipole approach

In this paper we argue that in the kinematic range given by 1 ≪ ln(1/αS) ≪ αS Y ≪ 1 αS , we can reduce the Pomeron calculus to the exchange of non-interacting Pomerons with the renormalized amplitude of their interaction with the target. Therefore, the summation of the Pomeron loops can be performed using the improved Mueller, Patel, Salam and Iancu approximation and this leads to the geometric...

True Coincidence Summing Corrections

Summing up Dirichlet Instantons.

We investigate quantum corrections to the moduli space for hypermultiplets for the type IIA string near a conifold singularity. We find a unique quantum deformation based on symmetry arguments which is consistent with a recent conjecture. The correction can be interpreted as an infinite sum coming from multiple wrappings of the Euclidean Dirichlet branes around the vanishing cycle. [S0031-9007(...
