Abstract:Symmetry violation under the combined transformation of charge (C), parity (P), and time reversal (T) in the charged leptonic sector can be sought through the non-vanishing expectation value of certain angular correlation operators that are odd under the CPT transformation. Here, we discuss the experimental approach for a CPT symmetry test by measuring angular correlations between the spin and momenta of photons originating from ortho-positronium (o-Psโ3๐พ) decays. This experiment is performed with the J-PET d… Show more
