M. N. Achasov, V. M. Aulchenko, S. E. Baru +39
Short overview of experiments with SND detector at VEPP-2M e^+e^- collider in the energy range 2E = 400 - 1400 MeV and preliminary results of data analysis are presented.
Evidence of the PHI(1020)--->ETA+PI0+GAMMA Decay
M. N. Achasov, V. M. Aulchenko, S. E. Baru +24
Signal of the rare radiative decay PHI--->ETA+PI0+GAMMA was observed in the SND experiment at VEPP-2M electron-positron collider.The result is based on the analysis of data, corres…
Experimental study of the decay PHI(1020)--->ETA+GAMMA in multi-photon final state
M. N. Achasov, S. E. Baru, A. V. Berdyugin +24
In the SND experiment at VEPP-2M e^+e^- collider the phi(1020) ---> eta+gamma ---> 3pi^0+gamma decay was studied. The branching ratio B(phi--->eta+gamma) = (1.246 +- 0.025 +- 0.057…
First Observation of PHI(1020)--->PI0+PI0+GAMMA Decay
M. N. Achasov, V. M. Aulchenko, A. V. Berdyugin +25
In the SND experiment at the VEPP-2M electron-positron collider the PHI(1020)--->PI0+PI0+GAMMA decay was studied. The branching ratio B(PHI--->PI0+PI0+GAMMA)=(1.14+-0.10+-0.12)x10^…
