The experiments NA64 and GBAR aiming to explore the still unanswered questions in physics of the existence of dark matter and the matter- antimatter asymmetry, respectively, are presented in the scope of this thesis. NA64 is an experiment at CERN searching for a new U0(1) gauge boson, A0 (dark photon) which may mediate the interaction of dark matter with ordinary matter via a very weak force. The experiment is sensitive to the still unexplored area of gamma-A0 mixing strength 10^-5 < e < 10^-3 and masses MA0 |
