Group constraint relations for five-point amplitudes in gauge theories with SO(N) and Sp(2N) groups
نویسندگان
چکیده
Linear constraint relations among loop-order five-point color-ordered amplitudes in SO(N) and Sp(2N) gauge theories are derived with the group-theoretic method. These constrains up to four-loop order. It is found that both theories, there n=6,22,34,44,50 linear at L=0,1,2,3,4 loop orders. Then numbers of independent under constraints respectively nind.=6,12,22,34,50. We find number begins diverge from SU(N) This provides an evidence on argument depend properties group algebras. Some comments given future study along this direction.

Recursion Relations for Tree Amplitudes in Super Gauge Theories
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 ...

Instanton sums and five-dimensional gauge theories
We analyze the vector multiplet prepotential of d = 4, N = 2 type IIA compactifications. We find that the worldsheet instanton corrections have a natural interpretation as one-loop corrections in five dimensions, with the extra dimension being compactified on a circle of radius gsls. We argue that the relation between spacetime and worldsheet instantons is natural from this point of view. We al...
متن کاملDyonic Instantons in Five-Dimensional Gauge Theories
We show that there exist finite energy, non-singular instanton solutions for fivedimensional theories with broken gauge symmetry. The soliton is supported against collapse by a non-zero electric charge. The low-energy dynamics of these solutions is described by motion on the ADHM moduli space with potential. Introduction Instantons appear as BPS particle-like configurations in five-dimensional ...
