Using samples of 106M $\psi(2S)$ events and 226M $J/\psi$ events collected with the Beijing Spectrometer (BESIII) at the Beijing Electron-Positron Collider, we report preliminary results on charmonium decay and Light Hadron Spectroscopy. These include $\chi_{cJ}$ to 4$\pi^0$, VV ($V=\omega$ or $\phi$), $\gamma V$ ($V=\omega$, $\rho$ or $\phi$), $\psi(2S) \to \gamma \gamma J/\psi$, the...

81. Recent results on hadron spectroscopy at COMPASS

oral

COMPASS is a multi-purpose fixed target experiment at CERN's Super Proton Synchrotron, dedicated to the study of the structure of the nucleon and the spectroscopy of hadrons. The large acceptance and high resolution two stage spectrometer takes advantage of the availability of a variety of high intensity beams (muons and hadrons) with momenta up to 300 GeV/c. During two weeks in 2004 and the...

99. Spectroscopy results from BaBar

This talk intends to shortly summarize the recent results on Spectroscopy, published from the $BaBar$ Collaboration. The $BaBar$ experiment is a B-factory, at SLAC, where asymmetric energy beams of electron-positron are accelerated and collide at the energy in the center of mass of $\Upsilon$(4S). In 9 years of data taking, $BaBar$ had collected 433 fb$^{-1}$ equivalent luminosity...

The B-factoy experiment at the high luminosity storage ring offers excellent opportunities in quarkonium spectroscopy. Recent results obtained in this field at Belle and related results are reported.

35. Charmonium and Heavy Flavour Production at LHCb

Spectroscopy

oral

Charmonium Production at LHCb The underlying mechanism for the production of prompt charmonium at hadron colliders is a topic of great theoretical interest. Furthermore, charmonium can also be exploited as a tag of b-production. LHCb studies will be shown using data accumulated in the 2010 run which address these issues. Measurements of production will be presented for both prompt and...

63. Measurement of J/psi, Upsilon and b-hadron production in proton-proton collisions at sqrt(s) = 7 TeV

Spectroscopy

oral

Measurements of the J/psi and Upsilon production cross sections in proton-proton collisions at 7 TeV by the CMS experiment are presented. The dimuon decay channel is used for both analyses. For the J/psi, inclusive and prompt differential cross sections versus transverse momentum are presented, as well as the beauty fraction, statistically separating the two contributions through a fit to the...
