Beyond cusp anomalous dimension from integrability in SYM
Davide Fioravanti, Paolo Grinza, Marco Rossi
We study the first sub-leading correction to the cusp anomalous dimension in the high spin expansion of finite twist operators in SYM theory. This term…

Strong coupling for planar SYM theory: an all-order result
Davide Fioravanti, Paolo Grinza, Marco Rossi
We propose a scheme for determining a generalised scaling function, namely the Sudakov factor in a peculiar double scaling limit for high spin and large twist operators belonging t…

Form factors in the massless coset models su(2)_k+1 \otimes su(2)_k /su(2)_2k+1 - Part II
P. Grinza, B. Ponsot
Massless flows from the coset model su(2)_k+1 \otimes su(2)_k /su(2)_2k+1 to the minimal model M_k+2 are studied from the viewpoint of form factors. These flows include in particul…
