Hi Ralph,

You can take a look at the Geant4 source code for QGSP_BERT (or any other)
physics list to see what physics is included in a particular list.

For QGSP_BERT see:

$G4INSTALL/source/physics_lists/lists/include/QGSC_BERT.hh
$G4INSTALL/source/physics_lists/lists/include/QGSC_BERT.icc

The physics lists have recently migrated to be of type G4VModularPhysicsList, 
which allows you to add as many different physics "builders" as you wish.  The  
physics builders add prewritten physics packages to your active physics list (so 
that you don't have to write all the code yourself and risk making mistakes).  
You can find which individual physics processes are included in the builders by 
looking at the source code for each builder.  For example, to see what physics 
processes are included in G4EmStandardPhysics, look at:

$G4INSTALL/source/physics_lists/builders/src/G4EmStandardPhysics.cc

Hope this helps.

~Zach
