Observation af the Omega(0)(c) charmed baryon at CLEO
Abstract
The CLEO experiment at the CESR, collider has used 13.7 fb(-1) of data to search for the production of the Omega (0)(c) (css ground state) in e(+)e(-) collisions at roots similar or equal to 10.6 GeV. The modes used to study the Omega (0)(c) are Omega (-)pi (+), Omega (-)pi (+)pi (0), Xi (-)K(-)pi (+)pi (+), Xi (0)K(-)pi (+), and Omega (-)pi (+)pi (+)pi (-). We observe a signal of 40.4 +/- 9.0(stat) events at a mass of 2694.6 +/- 2.6(stat) 1.9(stat) MeV/c(2), for all modes combined.
