New Dual Conformally Invariant Off-Shell Integrals
Evidence has recently emerged for a hidden symmetry of scattering amplitudes in N = 4 super Yang-Mills theory called dual conformal symmetry. At weak coupling the presence of this symmetry has been observed through five loops, while at strong coupling the symmetry has been shown to have a natural interpretation in terms of a T-dualized AdS5. In this paper we study dual conformally invariant off...
متن کاملNuclear structure functions and off-shell corrections
The n-th moments of the nuclear structure function FA 2 (x,Q 2) are analyzed using the off-shell kinematics appropriate to describe deep inelastic electron-nucleus scattering within the impulse approximation. It is shown that off-shell effects are sensitive to the form of both the nuclear spectral function and the nucleon structure function FN 2 (x,Q 2), and can be as large as ∼ 10% at Q2 ∼ 2 (...
متن کاملGeneral massive one-loop off-shell three-point functions
In this work we compute the most general massive one-loop off-shell three-point vertex in D-dimensions, where the masses, external momenta, and exponents of propagators are arbitrary. This follows our previous paper in which we have calculated several new hypergeometric series representations for massless and massive (with equal masses) scalar one-loop three-point functions, in the negative dim...
متن کاملOn the continuation of the dual amplitude with Mandelstam analyticity off mass shell
A model for the Q2-dependent modified dual amplitude with Mandelstam analyticity (M-DAMA) is proposed. M-DAMA preserves all the attractive properties of DAMA, such as its pole structure and Regge asymptotics, and leads to a generalized dual amplitude A(s,t,Q2). This amplitude can be checked in the known kinematical limits, i.e. it should reduce to onshell hadronic scattering amplitude for Q2 = ...
متن کاملOff-shell String Physics *
Recent advances in non-critical string theory allow a unique continuation, preserving con-formal invariance, of critical Polyakov string amplitudes to off-shell momenta. These continuations possess unusual, apparently stringy, characteristics, which are unlikely to be reproduced in a string field theory. Thus our results may be an indication that some fundamentally new formulation, other than s...
