Measurement of the pp→ppπ0 reaction at 850 MeV/c and partial wave cross sections
Year: 2002
Type: article
Abstract: A stack of annular detectors made of high purity germanium was used to measure $p\stackrel{\ensuremath{\rightarrow}}{p}\mathrm{pp}{\ensuremath{\pi}}^{0}$ differential cross sections at a beam momentum of 850 $\mathrm{MeV}/c.$ A total cross section of $\ensuremath{\sigma}=9.1\ifmmode\pm\else\textpm\fi{}1.1 \ensuremath{\mu}\mathrm{b}$ is deduced. The fitted distribution of different partial waves to the world total cross section data and to the present differential cross sections favors an approach without low-energy approximations, with the standard value for the final state interaction scattering length, and an important contribution from an intermediate $N\ensuremath{\Delta}$ state.
