Weights and recursion relations for ϕ p tree amplitudes from the positive geometry
Abstract Recently, the accordiohedron in kinematic space was proposed as the positive geometry for planar tree-level scattering amplitudes in the ϕ p theory [1]. The scattering amplitudes are given as a weighted sum over canonical forms of some accordiohedra with appropriate weights. These weights w...
