Direct X(3872) production in e+e- collisions
Direct production of the charmonium-like state in
collisions is considered in the framework of the vector meson dominance model.
An order-of-magnitude estimate for the width is found to
be 0.03 eV. The same approach applied to the charmonium
decay predicts the corresponding width of the order 0.1 eV in agreement with
earlier estimates. Experimental perspectives for the direct production of the
charmonia in collisions are briefly discussed.Comment: LaTeX2e, 11 pages, 1 figure, version published in Phys.Lett.
KLOE results at the Frascati -factory DANE
The KLOE experiment at the Frascati -factory DANE has collected
about 0.5 fb of data till the end of the year 2002. These data allow to
perform a wide physics program, ranging from the physics of charged and neutral
kaons to radiative -decays. Results are presented for the lifetime
and the semileptonic processes . From the light meson
spectroscopy program, results on the decays as well as are presented.Comment: 5 pages, 3 figures, Proceedings contribution to the 10th Int.
