Physics with the initial state radiation events at B-factory experiments

摘要

Initial state radiation (ISR) events produced in e(+)e(-) collisions at the gamma(4S) energy region can provide access to e(+)e(-) annihilations at lower C. M. energies. At B-factory experiments the data rate is substantial for physics at all energies below the gamma(4S). This paper describes the tagging of the ISR events, and identifies several physics topics that can be studied with the ISR data. [References: 10]
