Kinematics

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
If multiple processes are specified, using a single colon as in the previous example will apply the kinematics to all processes. If different kinematics is desired for each process, then the :n: notation can be used as in:
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
where n corresponds with the process number as entered in the batch file.

For decays, add "Decay" to the beginning of the key phrases.
