The fruitful run 2016/2017 is finished. The data was collected in the energy range of 640-1003.5 MeV per beam (experiment 'HIGH2017'). The total integrated luminosity amounts to 53 pbn-1 per each detector, that is comparable to the data collected during three runs 2010-2013, and exceeds the total data collected by several generations of detectors at VEPP-2M (predessor of VEPP-2000). These excellent results were achieved due to usage of new powerful BINP Injection Complex and of course due to hard work of skilled VEPP-2000 team.
Some extra-data was collected at three points of beam energy scan: around 938 MeV at the treshhold of nucleon-antinucleon pair production; at the D*0-meson mass 2*1003.5 MeV; and at 641 MeV per beam. Latter two regions are interesting to check if some new physics can be detected in "forbidden" (by Standart Model) processes.
