Measurement of the γ*γ*→ η' transition form factor and of the e+e−→ π+π−π0π0π0 and π+π−π0π0η cross sections by BABAR
Two recent studies from the BABAR experiment at SLAC on low-energy hadronic final states in e+e− annihilations are presented. The first study provides the first-ever measurement of the γ*γ*→ η' transition factor, where γ* denotes an off-shell photon. The second study provides the first-ever meas...
