Query: Measurement of the Omega_c^0 lifetime   We report a precise measurement of the Omega_c^0 lifetime. The data were
taken by the SELEX (E781) experiment using 600 GeV/c Sigma-, pi- and p beams.
The measurement has been made using 83+/-19 reconstructed Omega_c^0 in the
Omega- pi- pi+ pi+ and Omega- pi+ decay modes. The lifetime of the Omega_c^0 is
measured to be 65 +/- 13(stat) +/- 9(sys) fs.
