Photoproduction of pi0pi0 and pi0pi+-pairs off the proton from threshold to the second resonance region

F. Zehr, B. Krusche, P. Aguar +59

Precise total cross-sections and invariant-mass distributions have been measured for photoproduction of pion pairs off the proton producing $p{\pi }^0{\pi }^0$ and $n{\pi }^{+}{\pi }^0$ final states fro…
