Search for rare φ decays in π+π-γ final state

A search for phi radiative decays has been performed using a data sample of about 2.0 million phi decays collected by the CMD-2 detector at VEPP-2M collider in Novosibirsk. From the selected e(+)e(-) --> pi(+)pi(-)gamma events the following results were obtained: B(phi --> f(0)(980)gamma) < 1 x 10(-4) for destructive and B(phi --> f(0)(980)gamma) < 7 x 10(-4) for constructive interference with the Bremsstrahlung process respectively, B(phi --> gamma --> pi(+)pi(-)gamma) < 3 x 10(-5) for E-gamma > 20 MeV, B(phi --> rho gamma) < 7 x 10(-4). From the selected e(+)e(-) --> mu(+)mu(-)gamma events B(phi --> mu(+)mu(-)gamma) = (2.3 +/- 1.0) x 10(-5) has been obtained for E-gamma > 20 MeV. The upper limit on the P,CP-violating decay eta --> pi(+)pi(-) has also been placed: B(eta --> pi(+)pi(-)) < 9 x 10(-4). All upper limits are at 90% C.L. (C) 1997 Published by Elsevier Science.
