Abstract: The corner stone of standard model of particle physics is the Lorentz symmetry. It was shown that Lorentz symmetry translates to the join conservation of the three discrete symmetries of Charge inversion, Parity inversion and Time inversion. This equivalence is known as CPT theorem. Neutral Kaond weak ecay showed that CP symmetry is violated. Violation of CP symmetry is allowed by the CPT theorem, if T-symmetry is also violated. But to date no CP or T-symmetry violation has been observed in any strong force mediated process. This is known as the Strong-CP problem.
Some authors showed that introduction of a mirror realm (which does not interact with our real realm) could solve the Strong-CP problem and that neutral particles such as neutrons may spontaneously oscillate to their mirror universe counterpart. Some experiments, reporting negative observations, have already been performed but inconsistent results call for a new experiment to verify or disprove this scenario.
