Minutes

Present: Tyler & ig.

Tyler shows a promising peak for the pi0 (exactly where the Primakoff peak is expected to be) for incident photon-beam beam between 3 and 7 GeV. Tyler will ask Ilya for his event generator/cross-section calculator so that he can do a data/simu comparison. And ig showed a promising peak for eta to pi^-pi^+pi^0 where the Primakoff peak is expected to be (but for all incident photon-beam).
