A number of production cross sections for electron-positron annihilation to hadronic final states have been measured using the Belle data set. This is possible given that the Belle detector is a general purpose detector with a large solid angle coverage. The cross section measurements predominantly fall into two categories: cross sections at, or near, the machine operating energy, and cross...

3. Pion form factor and reactions $e^+e^-\to\omega\pi^0$ and $e^+e^-\to\pi^+\pi^-\pi^+\pi^-$ at energies up to 2 -- 3 GeV in the many-channel approach.

Using the field-theory-inspired expression for the pion electromagnetic form factor $F_\pi$, a good description of the data in the range $-10<s<1$ GeV$^2$ is obtained upon taking into account the pseudoscalar-pseudoscalar (PP) loops. When the vector-pseudoscalar (VP) and the axial vector-pseudoscalar (AP) loops are taken into account in addition to the PP ones, a good description of...
