| Among the ground state charmed hadrons the\Omega 0 c is the least known particle. It has so far been observed in a few decay channels only and with low statistics. Using a data sample of 1993 from the CERN hyperon beam experiment WA89 the\Omega 0 c has been found in 7 decay modes which cover final states with\Omega \Gamma , \Xi \Gamma and . We present a measurement of the\Omega 0 c mass and its lifetime. 1 Introduction The \Omega 0 c (ssc) is the least well known weakly decaying charmed baryon. First found in the former hyperon beam experiment WA62 [1] it has been seen by Argus [2] and E687 [3]. These experiments found the\Omega 0 c in four different decay channels. In the following we present new data on the\Omega 0 c in seven decay modes obtained in the CERN hyperon beam experiment WA89. The measured lifetimes of the three charmed baryons + c (udc), \Xi + c (usc), \Xi 0 c (dsc) differ by almost a factor of 4. For the \Xi 0 c decay the direct decay and the deca... | |||||||||||||
