WebThe derivation essentially follows Ref. 1. Consider an arbitrary fixed point (q(0),p(0)) in phase space at t = t(0) = t¯ (0). Because of translation symmetry, we may assume that the point … WebApr 13, 2024 · Therefore I’ve written similar code in C++ to achieve more efficient performance. And it worked well for 3-body decays. But unfortunately for 4 and 5-body decays it turned out to be again too cpu consuming calculation as the complexity grows as n^m, where m is dimension of phase-space (number of final-state particles). $\endgroup$ –
