Hit Collection: neutrons, HP

Particles, Track, Event, Run and Biasing
1

Hello everyone,

I am trying to collect the neutron hit positions in a detector. After each event I extract the positions from the hit collection. This works when I used regular physics models such as QGSP_BERT, however, using HP models like QGSP_BERT_HP, no neutrons are in the hit collections, although all other types of particles can be found there.

I would appreciate any suggestion on how to get the neutron hit positions using HP physics models.

Thank you.

If there are differences, they would come from physics itself and not from hit collection.
Please, run example Hadr03 (see readme) , or tell us what is the material of your detector and energy of the incident particle.
