Psi'' decays to charmless final states | | Jonathan L. Rosner
; | | Date: |
31 Oct 2004 | | Journal: | Annals Phys. 319 (2005) 1-12 | | Subject: | hep-ph | | Abstract: | The importance of measuring the non-$D ar D$ decays of the $psi’’ = psi(3770)$ resonance is discussed. These decays can shed light on a possible discrepancy between the total and $D ar D$ cross sections at the $psi’’$, and on a proposed mechanism for enhancement of penguin amplitudes in $B$ meson decays through charm--anticharm annihilation. Measurements (including the $psi’’$ line shape) in states of definite G-parity and in inclusive charmless final states such as $eta’ + X$ are found to be particularly important. | | Source: | arXiv, hep-ph/0411003 | | Services: | Forum | Review | PDF | Favorites | |
