  1. CONVENTIONAL CHARMONIA

  2. 0. Introduction • Observation of new conventional charmonium states • 1.1 c(2S) • 1.2 c2 (2P) • 1.3 X(3940)/X(4160) • 1.4 X(4630) • 2. Observation of new decay modes of known charmonia • 2.1 c • 2.2 ψ(4040/4160)  DD, DD*, D*D* • 2.3 ψ(4415)  DD2 • 3.Measurements of parameters (mass, width, Br) • 3.1 c mass and width, transition FF • 3.2 J/ψ: Γee, Γtot from ISR • 3.3 c0 andc2 • 3.4 ψ(3770) mass and width • 4. Production • 4.1 in B-decays • 4.2 in ee annihilation • 4.3 in gamma-gamma • 4.4 in ee annihilation at threshold (ISR) • 5. Theoretical insights Outline of the section. The major part of the section has been written Minor experimental subsections still have to be written Theoretical/overview of experimental status introduction is not ready Theoretical insights (conclusion on new B&B results) will be done by Nora within few weeks Omitted due to large overlapping with other sections

  3. Spin quarks Total momentum n2S+1LJ Radialexcitation Orbital momentum ...10 states were discovered before 1980, no one 1980-2002 J = S + L P = (–1)L+1parity C = (–1)L+Scharge conj. ...4 candidates to the standard charmonium have been observed since 2002 by B&B hc have been observed by CLEO in 2003

  8. to be written 0.5 page unexpected present from ISR conveners. After minor accommodation fits our section well (1.5 pages)

  9. Contributors: Korneliy Todyshev (BaBar) Anna Vinokurova (Belle) to be written ~2 pages do not need to describe analyses  just review the results (except for c transition FF)

  10. Contributor: Timofey Uglov (Belle) ~1.5 pages

  11. Contributor: Pasha Pakhlov (Belle) ~2 pages Contributor: Nora Brambilla (theory) to be written ~1-2 pages
