OSQAR Annual Report 2020

Ongoing activities and future plans for OSQAR experiments are briefly reviewed. These concern OSQAR-CHASE, OSQAR-VMB and OSQAR-LSW looking for new hypothetical particles at the low energy frontier, i.e. eV/sub-eV range, that could also explained the origin of Dark Energy and Dark Matter. Upgrades of these experiments have been presented and discussed within the scope of the Physic Beyond Collider (PBC) working group at CERN in synergy with other similar European initiatives from which VMB@CERN and JURA initiatives have emerged.
