Hi Everyone, Peter reminded me that I didn't specify which sections of the lengthy Voloshin paper to discuss tomorrow. We will discuss the charmonium spectrum in section 2.1 and the new states (X(3872) and higher) in sections 6.2 and 6.3, and the various explanations put forward for their existence (molecules, tetraquarks, ... ) .

Cowan <[log in to unmask]> To: [log in to unmask] Subject: LQS Group Meeting, Tuesday, March 4, 3 PM Eastern Hi Everyone, Our next LQS group meeting will be Tuesday, Mar. 4, at 3 PM Eastern/12 noon Pacific. Those of us at MIT can meet in the LNS conference room; those at SLAC, in the ROB offices. The phone conference people assure me that our previous passcode will work: 510-665-5437, passcode 7336. If it doesn't, I'll send out an alternate by email to this list. Agenda: 1) Roundtable reports. 2) Discussion of Voloshin's charmonium review paper, arxiv:0711.4556, "Charmonium". The paper is too big to send through our mailing list server, so you can find it at http://arxiv.org/pdf/0711.4556. Reminder: all posts to lqs-l are archived for online viewing at http://www.slac.stanford.edu/cgi-bin/lwgate/LQS-L/. Thanks much, --Ray
