I am beginning to look at the Lorentz-vectors of each cluster and reconstruct an invariant mass for each possible cluster pair, specifically focusing on Pi naughts at this point. However, there seems to be a problem with my use of the TLorentzVector operations, and no actual masses could be reconstructed. Tomorrow I plan on working out the kinks -- which includes finding them -- and getting the computer to output some masses. 

      As I write code, I'm thinking about how I'm going to incorporate charged particles into the process, in hopes of finding Eta and Rho's, among other things.
