b1pi Overview
- Generated 10000 X(2000) -> b1π-; events following the instructions here.

b1pi Event Count
# Generated events = 10000 # Events with 2+ photons = 9660 # Events with 2+ π+'s = 7642 # Events with 2+ π-'s = 8156 # Events with 2+ protons = 1040 (should only be 1 !!) # Events with enough tracks for the X (2+ photons, 2+ π+'s, 2+ π-'s) = 6076
