As the number of final state particles increases, it can be very helpful to specify the "kinematics" which helps CalcHEP in the numerical integration stage. This is done in exactly the same notation as in CalcHEP. The numbering corresponds to the order the particles are entered in the process in the batch file. Here is an example:
Kinematics | : | 12 -> 34 , 56 |
Kinematics | : | 34 -> 3 , 4 |
Kinematics | : | 56 -> 5 , 6 |
Kinematics | :1: | 12 -> 34 , 56 |
Kinematics | :1: | 34 -> 3 , 4 |
Kinematics | :1: | 56 -> 5 , 6 |
Kinematics | :2: | 12 -> 3 , 456 |
Kinematics | :2: | 456 -> 45 , 6 |
Kinematics | :2: | 45 -> 4 , 5 |
For decays, add "Decay" to the beginning of the key phrases.
