When do you need this done?

I'v the /Review of Particle Physics/ (2006, 1232 pages!) with me. In
the summary tabula there are 157 mes=F2ns, 103 confirmed, 96 further
states; 127 baru=F2ns, 75 confirmed, 12 further states--antis count as
the same. Nearly all of these are greater-mass/momentum excitations
of the same quark compounds. (Would you count the nearly-infinite
energy levels of hydrogen as separate atoms?) A handful are
composite: glueballs, dimes=F2ns, dibaru=F2ns, maybe three pentaquarks.
