Download or read book Charmed Meson Spectroscopy written by Robert K. Kutschke and published by . This book was released on 2004 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the two years since HQL02, the long sought j{sub {ell}} = 1/2 states have been observed. In the charmed non-strange sector, these states have the expected properties but, in the charmed strange sector, the states have masses below threshold for the otherwise dominant decay modes, allowing their observation in suppressed modes. Improved measurements of the masses and widths of the well established P-wave charm states have also been published.
