Abstract
In the previous chapter we presented the standard approach in defining kinematical variables and the phase-space. There is however, an alternative way of defining these variables and it is in terms of invariant masses and angles of pairs of particles in their center of mass reference system. This approach is very common for studying very rare decays (such as \(B\rightarrow K^* \ell \ell \)). Here we present the kinematics and phase space for one-to-three and one-to-four body decays.
