Meson Spectroscopy at COMPASS
QCD predicts four quark states or gluonic excitations like hybrids or glueballs to contribute to the meson spectrum in addition to qq pair configurations. The most promising way to identify such states is the search for JPC quantum number combinations which are forbidden in the constituent quark model. The fixed target COMPASS experiment at CERN offers the opportunity to search for such states ...

متن کاملExclusive meson production at COMPASS
In this paper we summarize recent measurements of exclusive meson production performed by the COMPASS Collaboration. In particular, recent results on the transverse target spin asymmetries for exclusive ρ0 production are presented. Some of these asymmetries are sensitive to the GPDs E, which are related to the orbital angular momentum of quarks. Other asymmetries are sensitive to the chiral-odd...
متن کاملTransverse Spin Effects at COMPASS
The measurement of transverse spin effects in semi-inclusive deepinelastic scattering (SIDIS) is an important part of the COMPASS physics program. In the years 2002-2004 data was taken by scattering a 160GeV/c muon beam off a transversely polarized deuteron target. In 2007, additional data was collected on a transversely polarized proton target. New preliminary results for the Collins and Siver...
متن کاملTransverse Spin Effects at COMPASS
The investigation of transverse spin and transverse momentum effects in deep inelastic scattering is one of the key physics programs of the COMPASS collaboration. In the years 2002-2004 COMPASS took data scattering 160 GeV muons on a transversely polarized LiD target. In 2007, a transversely polarized NH3 target was used. Three different channels to access the transversity distribution function...
