num_ps_pts (int) – Total number of phase space points to generate.
masses (numpy.ndarray) – List of masses of the initial state and final state particles.
cme (double) – Center-of-mass-energy of the process.
mat_elem_sqrd ((double)(numpy.ndarray) {lambda klist: 1}) – Function for the matrix element squared.
num_cpus (int {None}) – Number of cpus to use in parallel with rambo. If not specified, 75% of
the cpus will be used.
Returns:
cross_section (double) – Cross section for X -> final state particles(fsp), where the fsp have
masses masses and the process X -> fsp has a squared matrix element
of mat_elem_sqrd.
