Resonant production of A + baryons in neutrino-nucleus interactions in a photographic emulsion
A significant fraction, 0.5 8 + °227, of the charmed ìÓ+ baryons in neutrino interactions may be produced through the decays of 2C resonances. Three of four detected events involving ìÓ+ production are interpreted as the production and decay of charmed Σ° (2450), Σ+ + (2450) and2+ + (2510) resonances by the 2C ->ž ìÓ+ π ± mechanism. The mean value of the mass difference between lc (2450) and ì + is 162 ± 2 MeV/c2.
