Dear All,

I am sorry, I missed today CLAS meeting. We got some snow in Northern
Virginia. Let me make some comment addressed to the Volker's  discussion "Did
we miss a new Cascade state in our own CLAS data?"

Everybody knows that every resonance has a family.  Then the question is
what is the family of this Xi(1620) which Belle reported recently?  This
resonance looks as a member of the S-wave octet.  Back to 1970, Yakov
Azimov discussed this task in Phys. Lett. 32B, 499 (1970). Back to 2003, we
published a current status of members
of this octet (paper attached).  The motivation came from the analysis of
the Hall A measurements.  In 2006, COSY reported a solid signal for
Sigma(1480) (paper attached).  It is good to see a good signal about a
second member of the octet.  The open question is the update a signal for
the Lambda(1330) and to look for a heavy nucleon N(1100) which nobody had a
chance to see...

Cheers, igor
