Resumen

We present preliminary results of the STAR experiment at RHIC on exotic particle searches in minimum bias Au+Au collisions at √s_N _N = 200 GeV. We observe a narrow peak at 1734±0.5±5 MeV in the ΛK_s⁰ invariant mass with width consistent with the experimental resolution of about 6 MeV within the errors. The statistical significance can be quantified between 3 and 6 σ depending on cuts and methods. If this peak corresponds to a real particle state it would be a candidate for the N⁰ or the Ξ⁰ I = 1/2 pentaquart states.
