Light Scalar Mesons in Central Production at COMPASS | | A. Austregesilo
; COMPASS collaboration

12 Feb 2016 | | Abstract: | COMPASS is a fixed-target experiment at the CERN SPS that studies the
spectrum of light-quark hadrons. In 2009, it collected a large dataset using a
$190,$GeV$/c$ positive hadron beam impinging on a liquid-hydrogen target in
order to measure the central exclusive production of light scalar mesons. One
of the goals is the search for so-called glueballs, which are hypothetical
meson-like objects without valence-quark content. We study the decay of neutral
resonances by selecting centrally produced pion pairs from the COMPASS dataset.
The angular distributions of the two pseudoscalar mesons are decomposed in
terms of partial waves, where particular attention is paid to the inherent
mathematical ambiguities. The large dataset allows us to perform a detailed
analysis in bins of the two squared four-momentum transfers carried by the
exchange particles in the reaction. Possible parameterisations of the mass
dependence of the partial-wave amplitudes in terms of resonances are also
discussed. | | Source: | arXiv, 1602.3991 | | Services: | Forum | Review | PDF | Favorites | |
