Abstract
The processes e(+)e(-) --> mu(+)mu(-) and e(+)e(-) --> pi(+)pi(-) have been studied with SND detector at VEPP-2M e(+)e(-) collider in the vicinity of phi(1020) resonance. The branching ratios B(phi --> mu(+)mu(-)) = (3.30 +/- 0.45 +/- 0.32) x 10(-4) and B(phi --> pi+pi-) = (0.71 +/- 0.11 +/- 0.09) x 10(-4) were obtained.
