Study of the Exclusive Initial-State-Radiation Production of the DDbar System

Description

A search for charmonium and other new states is performed in a study of exclusive initial-state-radiation production of D(bar D) events from electron-positron annihilations at a center-of-mass energy of 10.58 GeV. The data sample corresponds to an integrated luminosity of 384 fb-1 and was recorded by the BABAR experiment at the PEP-II storage ring. The D(bar D) mass spectrum shows clear evidence of the ψ(3770) plus other structures near 3.9, 4.1, and 4.4 GeV/c2. No evidence for Y (4260) → D(bar D) is observed, leading to an upper limit of Β(Y (4260) → D(bar D))/Β(Y (4260) → J/ψπ+π-) < 1.0 at 90% confidence level
