Detailed Description

Physics generators for neutrinos, cosmic rays, and others.

Enumeration Type Documentation

anonymous enum

Enumerate mother codes for primary particles.

Normally the mother code for a primary particle would be set to some arbitrary invalid value like -1, however, we can use this to mark the source of the particle as being either, eg., neutrino induced or from cosmic-rays.
