Description

Our studies are based on the 1 fb$^{-1}$ data, acquired by the SND detector with $e^+e^-$-collisions at VEPP-2000 in the $\sqrt{s}$=0.3–2 GeV energy range. We present the results of high precision measurements of the $e^+e^-\to\pi^+\pi^-$
and $e^+e^-\to\pi^+\pi^-\pi^0$
cross sections and their implications to the calculation of the Hadronic Contribution to the Muon (g-2). Also we report the results of the analysis of the $e^+e^-\to\pi^0\gamma$ and $e^+e^-\to\eta\gamma$ radiative
processes
near mass of the $\phi$-meson, the study of the cross sections of $e^+e^-\to n \bar{n}$
and $e^+e^-\to\omega\eta\pi^0\pi^0$
processes, the dalitz analysis of the $e^+e^-\to\pi^+\pi^-\pi^0$ process at
the energy range $\sqrt{s}$=1.05–2 GeV and the measurement
of the inclusive hadronic cross section for the processes with charged particles in the final state at 1.8 GeV <$\sqrt{s}$<2 GeV.
