On Radiative Weak Annihilation Decays | Richard F. Lebed
; | Date: |
22 Dec 2000 | Subject: | hep-ph | Abstract: | We discuss a little-studied class of weak decay modes sensitive to only one quark topology at leading order in G_F: M --> m gamma, where M,m are mesons with completely distinct flavor quantum numbers. Specifically, they proceed via the annihilation of the valence quarks through a W and the emission of a single hard photon, and thus provide a clear separation between CKM and strong interaction physics. We survey relevant calculations performed to date, discuss experimental discovery potential, and indicate interesting future directions. | Source: | arXiv, hep-ph/0012316 | Services: | Forum | Review | PDF | Favorites |
