The pp to pp pi pi- reaction studied in the low-energy tail of the Roper resonance
The pp to pp pi pi- reaction studied in the low-energy tail of the Roper resonance
Exclusive measurements of the pp-->pppi(+)pi(-) reaction have been carried out at T-p=775 MeV at CELSIUS using the PROMICE/WASA setup. Together with data obtained at lower energy, they point to a dominance of the Roper excitation in this process. From the observed interference of its decay routes...

Exclusive measurements of the pp-->pppi(+)pi(-) reaction have been carried out at T-p=775 MeV at CELSIUS using the PROMICE/WASA setup. Together with data obtained at lower energy, they point to a dominance of the Roper excitation in this process. From the observed interference of its decay routes N-*-->Nsigma and N-*-->Deltapi-->Nsigma, their energy-dependent relative branching ratio is determined. |
