Meson Production at COSY-TOF and COSY-ANKE
The roles of the COSY-TOF and COSY-ANKE spectrometers in the measurement of
strange meson production are briefly reviewed, mainly in connection with new
results on the pp -> K^+ p Lambda, pp -> K^+ p Sigma^0 and pp -> K^+ n Sigma^+
reactions.Comment: Invited talk at the MESON2010 conference in Krakow, June 201
Associated strangeness production in the pp to pK^+K^-p and pp to pK^+ pi^0 Sigma^0 reactions
The total and differential cross sections for associated strangeness
production in the and reactions
have been studied in a unified approach using an effective Lagrangian model. It
is assumed that both the and final states originate from
the decay of the resonance which was formed in the production
chain . The available experimental data
are well reproduced, especially the ratio of the two total cross sections,
which is much less sensitive to the particular model of the entrance channel.
The significant coupling of the resonance to is
further evidence for large components in the quark wave function of
the resonance.Comment: Published in Phys. Rev.
COSY-11 : How will we remember it ?
A personal selection is made of the highlights of the COSY-11 physics program
undertaken at the COoler SYnchrotron of the Forschungszentrum Juelich. This has
been particularly rich in the field of strange and non-strange meson production
in proton-proton and proton-deuteron collisions. The results are considered in
relation to experiments carried out at other facilities and with respect to
their impact on theory.Comment: Invited talk at the "Symposium on Meson Physics at COSY--11", Cracow,
June 2007. 14 pages + 12 eps figures. AIP conference styl
