Decay is kinematically forbidden #11

Closed ezfisher closed 7 years ago

ezfisher commented 7 years ago

Hi, I am using RapidSim in lxplus to simulate the decay of Bs0 -> J/psi phi and it is returning the error that the decay is kinematically forbidden. I see that the issue is for the some reason, the program is assigning the same nonexistent ID number to each particle and giving them a mass of 0 GeV. How do I go about fixing this? I've attached a screenshot of the error that RapidSim keeps throwing.

Thanks, Eric

The problem is that the “Bs” should be called “Bs0”.

Hi Eric,

It looks like you've forgotten to set the environment variable $RAPIDSIM_ROOT. This should point to the path where you have installed RapidSim. The particle data is then loaded from $RAPIDSIM_ROOT/config/particles.dat This is also the reason why you're getting warnings from RapidConfig::loadSmearing.
