Symmetries of the N=4 SYM S-matrix
Amit Sever, Pedro Vieira
Under the assumption of a CSW generalization to loop amplitudes in N=4 SYM, (1) We prove that, formally the S-matrix is superconformal invariant to any loop order, and (2) We argue…
Quark scattering amplitudes at strong coupling
John McGreevy, Amit Sever
Following Alday and Maldacena, we describe a string theory method to compute the strong coupling behavior of the scattering amplitudes of quarks and gluons in planar N=2 super Yang…
Scattering of twist fields from D-branes and orientifolds
Albion Lawrence, Amit Sever
We compute the two-point function for Z_N orbifold twist fields on the disk and RP2. We apply this to a computation of the O(g_s) correction to the Kahler potential for (the symmet…
Exact N=4 correlators of AdS(3)/CFT(2)
Ari Pakman, Amit Sever
We extend to chiral N=4 operators the holographic agreement recently found between correlators of the symmetric orbifold of M^4 at large N and type IIB strings propagating in AdS(3…
