Abstract I derive an all-order resummation formula for the logarithmically enhanced contributions proportional to α s n x ± ξ $$ \frac{\alpha_s^n}{x\pm \xi } $$ log ξ ± x 2 ξ k $$ {\left(\frac{\xi \pm x}{2\xi}\right)}^k $$ in the quark coeffici

Resummation of threshold logarithms in deeply-virtual Compton scattering

Autor: J. Schoenleber

Publikováno v: Journal of High Energy Physics

I derive an all-order resummation formula for the logarithmically enhanced contributions proportional to $\frac{\alpha_s^n}{x \pm \xi} \log (\frac{\xi \pm x}{2\xi})^k$ in the quark coefficient function of deeply-virtual-Compton scattering and the pio

Using the approach based on conformal symmetry we calculate the two-loop coefficient function for the vector flavor-nonsinglet contribution to deeply-virtual Compton scattering (DVCS). The analytic expression for the coefficient function in momentum
