Abstract

The Beijing Spectrometer (BES) Collaboration has observed exclusive pair production of Ds mesons at the Beijing Electron-Positron Collider (BEPC) at a center-of-mass energy of 4.03 GeV. The Ds mesons are detected in the φπ+, K¯ *0K+, and K¯ 0K+ decay modes; two fully reconstructed events yield the value (3.9−1.9−1.1+5.1+1.8)% for the Ds branching fraction to φπ. This is the first direct, model-independent measurement of this quantity.Received 28 April 1995DOI:https://doi.org/10.1103/PhysRevD.52.3781©1995 American Physical Society
