Study of the quasi-free np→npπ+π− reaction with a deuterium beam at 1.25 GeV/nucleon

Study of the quasi-free np→npπ+π− reaction with a deuterium beam at 1.25 GeV/nucleon

The tagged quasi-free np→npπ+π− reaction has been studied experimentally with the High Acceptance Di-Electron Spectrometer (HADES) at GSI at a deuteron incident beam energy of 1.25 GeV/nucleon (s∼2.42 GeV/c for the quasi-free collision). For the first time, differential distributions of solid statis...
