A search for πNN bound systems - Ashery, D.; Lichtenstadt, J.; Piasetzky, E.; Morris, C.L.; Zumbro, J.D.; Gilman, R.; Rawool, M.W.; Mordechai, S.; Fuentes, A.; Williams, A.; Boyer, B.; Moore, C.F.; et al. (Elsevier)
The d(π^+, π^-)T^+^+^+ and the d(π^-, π^+) T^- reactions were studied at an incident pion energy of 260 MeV. Outgoing negative pions were detected at 35^o and 55^o in the first reaction, and the positive pions at 45^o in the second. Indications for structures corresponding to a (π^+pp) system with a mass of 2003.0+/-1.0 MeV and a (π^-nn) system with a mass of 200.1+/-1.5 MeV were observed with marginal statistical significance. Upper limits for the cross sections are obtained.
