Measurement of additional radiation in the initial-state-radiation processes e+e-→μ+μ-γ and e+e-→π+π-γ at BABAR

In addition to the impressive new measurement of #gminus2 yesterday, there was an interesting development on 'theory' side, via experimental inputs to the R ratio method from BABAR : https://t.co/pU3BuGuoz8
