چکیده
The recently observed D sJ(2317) + meson is explained as a scalar cs̄ system which appears as a bound state pole, below threshold, in the DK scattering amplitude. The standard cs̄ 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 GeV−1.

With the identification of (DsJ (2317), DsJ (2460)) as the (0 , 1) doublet in the heavy quark effective field theory, we derive the light cone QCD sum rule for the coupling of eta meson with DsJ (2317)Ds and DsJ (2460)D ∗ s . Through η − π 0 mixing we calculate their pionic decay widths, which are consistent with the experimental values (or upper limits). Combining the radiative decay widths de...

The NEMO 3 detector, now operating in the Fréjus Underground Laboratory, is devoted to search for neutrinoless double beta decay ; the expected sensitivity for the effective neutrino mass (< mν >) is on the order of 0.1 eV. The performances of the tracking detector are presented. The first and very preliminary results concerning the background and the double beta signal are given.
