Scattering forms, worldsheet forms and amplitudes from subspaces
Abstract We present a general construction of two types of differential forms, based on any (n−3)-dimensional subspace in the kinematic space of n massless particles. The first type is the so-called projective, scattering forms in kinematic space, while the second is defined in the moduli space of n...
