Explaining the Ds(2317)
Abstract
The recently observed Ds(2317) meson is explained as a scalar c+anti-s system which appears as a bound state pole, below threshold, in the DK scattering amplitude. The standard c+anti-s charmed scalar Ds0 is found at about 2.9 GeV, with a width of some 150 MeV. For the scattering length of DK in S wave we predict 5+-1 1/GeV.
