摘要
The TPC/Two-Gamma facility at the SLAC e+e- storage ring PEP was used to study the reactions * and *e. The * and e* transition form factors were measured as functions of Q2, the negative of the invariant mass squared of the tagged photon, in the range 0.1<Q2<7 GeV2. These determinations of the electromagnetic structure of the and e mesons are consistent with both vector-meson dominance and QCD. They also provide new measurements of the pseudoscalar mixing angle and decay constants.
