Periodic Reporting for period 1 - OPSVIO (Ortho-positronium decay and the search for CP and CPT violation in leptonic sector)

In our universe, we observe asymmetry between the matter and antimatter. In 1967 A. Sahkarov proposed a solution requiring, among others, the existence of CP symmetry violation (C - charge conjugation, P - parity). This was indeed observed in the quark sector but at the...
