Fecha de publicación: | 15-ago-2009 | Editor: | Elsevier | Citación: | Nuclear Physics - Section A 827 (1-4): 249C-251C (2009) | Resumen: | We study the properties of the scalar charm resonances D-s0(2317) and D-0(2400), and the theoretical hidden charm state X(3700) in nuclear matter. We find that for the D-s0(2317) and X(3700) resonances, with negligible and small width at zero density, respectively, the width becomes about 100 MeV and 200 MeV at normal nuclear matter density, accordingly. For D-0(2400) the change in width is relatively less important. We discuss the origin of this new width and trace it to reactions occurring in the nucleus. We also propose a possible experimental test for those modifications in nuclear matter, which will bring valuable information on the nature of those scalar resonances and the interaction of D mesons with nucleons. | Descripción: | 18th Particles and Nuclei International Conference (PANIC08).
