Renormalization Group Improved Small-x Equation
We propose and analyze an improved small-x equation which incorporates exact leading and next-to-leading BFKL kernels on one hand and renormalization group constraints in the relevant collinear limits on the other. We work out in detail the recently proposed ω-expansion of the solution, derive the Green’s function factorization properties and discuss both the gluon anomalous dimension and the h...

متن کاملRenormalization-Group-improved perturbation theory
A method for computing the low-energy non-perturbative properties of SUSY GFT, starting from the microscopic lagrangian model, is presented. The method relies on covariant SUSY Feynman graph techniques, adapted to low energy, and RenormalizationGroup-improved perturbation theory. We apply the method to calculate the glueball superpotential in N = 1 SU(2) SYM and obtain a potential of the Venezi...
متن کاملRenormalization group improved BFKL equation ∗
The calculation of next-to-leading log x corrections to the BFKL equation was completed last year [1,2] after several years of theoretical effort. The results, for both anomalous dimension and hard Pomeron, show however signs of instability due to both the size and the (negative) sign of corrections, possibly leading to problems with positivity also [3]. If we write the eigenvalue equation corr...
متن کاملRenormalization group improved black hole spacetimes
We study the quantum gravitational effects in spherically symmetric black hole spacetimes. The effective quantum spacetime felt by a point-like test mass is constructed by “renormalization group improving” the Schwarzschild metric. The key ingredient is the running Newton constant which is obtained from the exact evolution equation for the effective average action. The conformal structure of th...
