New experimental data for the decays f → μ+μ− and f → π+π− from SND detector

Abstract The processes e + e − → μ + μ − and e + e − → π + π − have been studied with SND detector at VEPP-2M e + e − collider in the vicinity of f(1020) resonance. The branching ratios B ( f → μ + μ − ) = (3.30±0.45±0.32) × 10 −4 and B ( f → π + π − ) = (0.71±0.11±0.09) × 10 −4 were obtained.
