A confirming evidence for two pseudoscalar states with masses M1 = 1405 +- 5, Gamma1 = 50 +- 4 MeV/c2 and M2 = 1500 +- 10, Gamma2 = 100 +- 20 MeV/c2 is reported. The second pseudoscalar fills the nonet and leaves the first as an outsider supporting the hypothesis for its exotic nature.

Abstract
A confirming evidence for two pseudoscalar states with masses M1 = 1405 +- 5, Gamma1 = 50 +- 4 MeV/c2 and M2 = 1500 +- 10, Gamma2 = 100 +- 20 MeV/c2 is reported. The second pseudoscalar fills the nonet and leaves the first as an outsider supporting the hypothesis for its exotic nature.File in questo prodotto:
