SUMMARY:Aspects of twist-2 superfield operators in N=1 SYM theory
DESCRIPTION:Speaker: Giacomo Santoni (Istituto Nazionale di Fisica Nucleare) \nTwist-2 operators are fundamental for the study of deep inelastic scattering in QCD because they dominate the operator product expansions on the light-cone. Recently\, it was discovered that the Euclidean UV-asymptotic generating functional of the connected correlators of twist-2 operators provides highly nontrivial constraints on the yetto-come nonperturbative solution of large-N SU(N) YM theory. We extend these results to N=1 supersymmetric Yang-Mills (SYM) theory by providing a new construction of twist-2 operators in terms of covariant superfields. This construction is manifestly gauge-invariant and SUSY-covariant and makes their one-loop renormalization and mixing properties considerably transparent. We compute their asymptotic renormalization-group improved generating functional in Euclidean superspace and its planar and leading nonplanar large-N expansion. We verify that the leading nonplanar asymptotic renormalization-group improved generating functional matches the structure of logarithm of a functional superdeterminant of the corresponding nonperturbative object arising from the glueball/gluinoball effective action\, which it should be asymptotic to at short distances because of the asymptotic freedom.
