Sažetak
The results of a search for K^- p->pi^0pi^0pi^0 Lambda(where the 3pi^0's are not from eta-meson decay) are presented. The data were obtained with the Crystal Ball spectrometer at eight beam momenta from 514 to 750 MeV/c. For the six beam momenta below p_K^- = 714 MeV/c, no signal was found the 90% C.L. upper limit obtained for the K^- p->3pi^0 Lambda total cross section sigma_t varies between 2 and 7 &micro ; ; b. This small upper limit is indicative that spontaneous pi^0 emission is insignificant, since the K^- p->pi^0pi^0pi^0 Lambda threshold is at p_K^- = 397 MeV/c. A signal was observed only at p_K^- = 750 MeV/c, with sigma_t = 25&plusmn ; ; 7 &micro ; ; b. These results can be explained only if triple pi^0 production goes predominantly by hyperon resonance deexcitation, K^- p->Sigma*->pi^0Lambda^*. There are several candidates for the Sigma^* but only one for the Lambda^*, namely, the Lambda(1520)3/2^-, as the threshold for K^- p->pi^0 Lambda(1520) is at p_K^- = 704 MeV/c.
