Abstract
We present recent experimental results for e+eāˆ’ annihilation into hadrons below 2 GeV obtained with the SND detector at the VEPP-2000 collider. The analyses are based on data collected in the detector runs from 2010 to 2017. During the period from 2014 to 2016 collider and detector underwent significant upgrades which allowed an increase in luminosity and detector efficiency. In particular, results of studying $e^+ e^- \to \pi^+\pi^-$, $\eta \to e^+ e^- $, $e^+ e^- \to n\bar{n} $, $e^+ e^- \to K^+K^-\eta$, $e^+ e^- \to \pi^+\pi^-\eta$, $e^+ e^- \to K_{S}K_{L} \pi^0$, $e^+ e^- \to \pi^+\pi^-\pi^0\eta$, $e^+ e^- \to \omega\pi^0$, $e^+ e^- \to \pi^0\gamma$, and $e^+ e^- \to \pi^+\pi^-4\pi^0$ reactions are considered in this paper.
