hazma.rambo.generate_phase_space_point(masses, cme, num_fsp)¶

Generate a phase space point given a set of final state particles and a given center of mass energy.

Parameters:	masses (numpy.ndarray) – List of masses of the 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.
Returns:	phase_space_points (numpy.ndarray) – List of four momenta and a event weight. The returned numpy array is of the form {ke1, kx1, ky1, kz1, …, keN, kxN, kyN, kzN, weight}.
