Here is the list of experiments where Theta signal has been observed:

 LEPSDIANACLAS-dCLAS-pSAPHIRneutrinoHERMESSVD ,

 COSY-TOFDubna-1ZEUSDubna-2

And here is the list of experiments where the search result was negative:

 BESHERA-BPHENIX

The evidence for Theta stimulated the search and observation of signals of other
possible pentaquarks:

double-strange ones  NA49 (see, however,  its critique )

and anti-charmed one  H1
