The branching ratio $$\omega \rightarrow \pi ^+\pi ^-$$ ω→π+π- revisited
Abstract We analyze the most recent data for the pion vector form factor in the timelike region, employing a model-independent approach based on dispersion theory. We confirm earlier observations about the inconsistency of different modern high-precision data sets. Excluding the BaBar data, we find...
