Further evidence for a 70, L=2 baryon multiplet (F/sub 35/ (1877) decay)

The recently discovered f-wave dominance of the decay F/sub 35/(1877) to Delta pi is interpreted as requiring mixing between 56, L=2 and 70, L=2 baryon multiplets. This conclusion is drawn in the context of a broken version of SU(6)/sub W/. Further predictions include (a) the existence of a second p...

Sumario:The recently discovered f-wave dominance of the decay F/sub 35/(1877) to Delta pi is interpreted as requiring mixing between 56, L=2 and 70, L=2 baryon multiplets. This conclusion is drawn in the context of a broken version of SU(6)/sub W/. Further predictions include (a) the existence of a second prominent F/sub 15/ pi N resonance around 2 GeV in mass and (b) the more probable dominance of the 1.9 GeV enhancement seen in pi /sup +/p to Sigma /sup +/(1385)K/sup +/ by P/sub 33/ and P /sub 31/ rather than F/sub 37/ or F/sub 35/ resonances.
