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 کامل2 Meson Spectroscopy at LEAR with the
The CRYSTAL BARREL Collaboration has reported the discovery of the scalar mesons a 0 (1450) 1, 2] and f 0 (1370), together with a relatively narrow f 0 (1500), decaying into 0 0 3], 4], 0 5], K L K L 6] and 4 0 7]. The f 0 (1500) is interpreted as a glueball 8], but its precise KK decay rate has still not been measured precisely 6]. Also, a scalar ss meson decaying mainly into KK is needed to c...
متن کاملHeavy quark meson spectroscopy at CDF
With growing datasets collected by the CDF II experiment, studies of the spectroscopy of mesons containing heavy quarks become more exciting. The CDF experiment has good capabilities in both charm and bottom sector. This capability allowed also to contribute to the study of the zoo of states called X,Y, Z. In this area we present a recent update of the mass measurement of X(3872). The result m(...
