1-loop Color structures and sunny diagrams
Barak Kol, Ruth Shir
Recently the space of tree level color structures for gluon scattering was determined in arXiv:1403.6837 together with its transformation properties under permutations. Here we gen…

Perturbative gauge theory and 2+2=4
Barak Kol, Ruth Shir
The group of permutations on four elements has an irreducible representation corresponding to the partition 4=2+2. This representation appears in several different mathematic…

Color structures and permutations
Barak Kol, Ruth Shir
Color structures for tree level scattering amplitudes in gauge theory are studied in order to determine the symmetry properties of the color-ordered sub-amplitudes. We mathematical…
