High statistics search for the θ+(1.54) pentaquark state

Academic Article


  • We have searched for θ+(1.54) → K0 p decays using data from the 1999 run of the HyperCP experiment at Fermilab. We see no evidence for a narrow peak in the Ks0p mass distribution near 1.54 GeV/c among 106000 Ks0p candidates, and obtain an upper limit for the fraction of θ+(1.54) to Ks0p candidates of <0.3% at 90% confidence.
