Scalar-isovector K¯ production close to threshold
Scalar-isovector K¯ production close to threshold
The reaction pp --> dK(+) (K) over bar (0) has been investigated at excess energies Q=47.4 and 104.7 MeV above the K+(K) over bar (0) threshold at COSY Julich. Coincident dK(+) pairs were detected with the ANKE spectrometer, and subsequently similar to 2000 events with a missing (K) over bar (0)...

The reaction pp --> dK(+) (K) over bar (0) has been investigated at excess energies Q=47.4 and 104.7 MeV above the K+(K) over bar (0) threshold at COSY Julich. Coincident dK(+) pairs were detected with the ANKE spectrometer, and subsequently similar to 2000 events with a missing (K) over bar (0) invariant mass were identified, which fully populate the Dalitz plot. The joint analysis of invariant mass and angular distributions reveals s-wave dominance between the two kaons, in conjunction with a p-wave between the deuteron and the kaon pair, i.e. K (K) over bar production via the a(0)(+)(980) channel. Integration of the differential distributions yields total cross-sections of sigma(pp -->dK(+)(K) over bar (0))=(38 +/- 2(stat) +/- 14(syst)) nb and(190 +/- 4(stat) +/- 39(syst)) nb for the low and high Q value, respectively. |
