Hello,

please re-read your question:
"... what is exactlly option in case of undecaying ..."

What do you mean under the option?

Just take an example of the model from hepmd.soton.ac.uk

CalcHEP checks all possible decay channels for the particle and if there is none -- it is automatically stable

What exactly would you like to know?

Best,
Alexander
