TL;DR: The TPC/Two-Gamma experiment at the SLAC e-italic/sup +/e/sup -/ storage ring PEP has obtained a 95%-confidence-level limit of GAMMA/sub iota/sub ..-->..//sub ..gamma..// sub ..Gamma../B(iota..-->..KK-bar..pi..) which appears to conflict with previous assignments of an observed rho..gamma… decay to iota.
