Two-Pion Production in Proton-Proton Collisions with Polarized Beam

S. Abd El-Bary, S. Abd El-Samad, R. Bilger +46

The two-pion production reaction $\vec{p}p\to pp{\pi }^{+}{\pi }^{-}$ was measured with a polarized proton beam at $T_p\approx$ 750 and 800 MeV using the short version of the COSY-TOF spectrome…
