Recursion Relations for Tree Amplitudes in Super Gauge Theories
نویسندگان
چکیده
Using newly proposed recursion relations in [25, 26], compact formulas are obtained for tree-level amplitudes of g− 1 g − 2 g − 3 g + 4 g + 5 · · · g + n . We then make an extension of these recursion relations to include fermions of multi-flavors, from which MHV and MHV amplitudes are reproduced. We also calculate non-MHV amplitudes of processes with two fermions and four gluons. Results thus obtained are equivalent to those obtained by extended CSW prescriptions, and those by conventional field theory calculations.

On-Shell Recursion Relations for Generic Theories
We show that on-shell recursion relations hold for tree amplitudes in generic two derivative theories of multiple particle species and diverse spins. For example, in a gauge theory coupled to scalars and fermions, any amplitude with at least one gluon obeys a recursion relation. In (super)gravity coupled to scalars and fermions, the same holds for any amplitude with at least one graviton. This ...
متن کاملGenerating Tree Amplitudes in N = 4 SYM and N = 8 SG
We study n-point tree amplitudes of N = 4 super Yang-Mills theory and N = 8 supergravity for general configurations of external particles of the two theories. We construct generating functions for n-point MHV and NMHV amplitudes with general external states. Amplitudes derived from them obey SUSY Ward identities, and the generating functions characterize and count amplitudes in the MHV and NMHV...
متن کاملPerturbative Gravity and Twistor Space
Tree amplitudes in gravity theories can be computed from those of gauge theory using the KLT relations [1]. Inspired by this observation, investigations [2,3,4,5] have been carried out in the hope of discovering a deeper connection at the perturbative level between N = 8 supergravity [6] and N = 4 super Yang-Mills. A link between these theories, beyond structural similarities like the non-abeli...
متن کاملMulti-Leg One-Loop Gravity Amplitudes from Gauge Theory
By exploiting relations between gravity and gauge theories, we present two in nite sequences of one-loop n-graviton scattering amplitudes: the `maximally helicity-violating' amplitudes in N = 8 supergravity, and the `all-plus' helicity amplitudes in gravity with any minimally coupled massless matter content. The all-plus amplitudes correspond to self-dual eld con gurations and vanish in supersy...
متن کاملThe Noncommutative S-Matrix
As a simple example of how recently developed on-shell techniques apply to nonlocal theories, we study the S-matrix of noncommutative gauge theories. In the complex plane, this S-matrix has essential singularities that signal the nonlocal behavior of the theory. In spite of this, we show that tree-level amplitudes may be obtained by BCFW type recursion relations. At one loop we find a complete ...
