24 Sep 2011 | | Abstract: | New Crystal Barrel data are reported for pbar-p -> omega-pizero and pbar-p ->
omega eta-pizero with omega decaying to piplus-piminus-pizero. The shapes of
angular distributions agree well with those for data where omega ->
pizero-gamma; this is a valuable cross-check on systematic errors. The new data
provide good measurements of vector and tensor polarisations P_y, T20, T21 and
T22 of the omega. These lead to significant improvements in parameters of
several resonances reported earlier. New values of masses and widths (in Mev)
are: J^PC = 5^-- (2300+-45, 260+-75), J^PC = 3^-- (2260+-20, 160+-25), J^PC =
1^+- (2240+-35, 320+-85), and J^PC = 1^-- (2110+-35, 230+-50). A remarkable
feature of the data is that vector polarisation P_y is close to zero
everywhere. It follows that all interfering amplitudes have relative phases
close to 0 or 180 deg. Tensor polarisations are large. | | Source: | arXiv, 1109.5247 | | Services: | Forum | Review | PDF | Favorites | |
