Measurement of the Near-Thresholde+e−→D(*)±D(*)∓Cross Section using Initial-State Radiation

Measurement of the near-threshold e+e- --> D(*)+/-D(*)-/+ cross section using initial-state radiation.

We report a measurement of the exclusive e+e- -->D(*)+/-D*-/+ cross section as a function of center-of-mass energy near the D(*)+/-D*-/+ threshold with initial-state radiation. A partial reconstruction technique is used to increase the efficiency and to suppress background. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of 547.8 fb(-1).

Precise measurement of the e+e- --> pi+pi-(gamma) cross section with the initial state radiation method at BABAR.

A precise measurement of the cross section of the process e(+)e(-) --> pi(+)pi(-)(gamma) from threshold to an energy of 3 GeV is obtained with the initial state radiation (ISR) method using 232 fb(-1) of data collected with the BABAR detector at e(+)e(-) center-of-mass energies near 10.6 GeV. The ISR luminosity is determined from a study of the leptonic process e(+)e(-) --> mu(+)mu(-)gamma(gamm...
