Measurement of $e^+e^-\to D_s^{(*)+} D_s^{(*)-}$ cross sections near threshold using initial-state radiation
$e^+e^-\to D_s^{(*)+} D_s^{(*)-}$ cross sections threshold initial-state radiation
2011/1/4
We report a measurement of exclusive e+e− ! D()+s D()− s cross sections as a function of center-of-mass energy near D()+ s D()− s threshold with initial-state radiation. The anal...
Precise measurement of the e+e－→π+π－(γ) cross section with the initial state radiation method at BABAR
pion form factor ISR g-2 BABAR
2010/5/7
We present a precise BABAR measurement on the cross section of the process e+e－→π+π－(γ) from threshold to an energy of 3 GeV with the initial state radiation (ISR) technique, using 232 fb－1 of data co...
