Lineshape of the Lambda(1405) Hyperon Measured Through its Sigma0 pion0 Decay

I. Zychor, M. Büscher, M. Hartmann +12

The pp -> p K+ Y0 reaction has been studied for hyperon masses m(Y0)<1540 MeV/c2 at COSY-Juelich by using a 3.65 GeV/c circulating proton beam incident on an internal hydrogen targ…
