In this work, we analyse the same asymmetries for eson system. We also discuss the complexity in this case over B meson. Expressions are derived in terms of two complex parameters, nd which govern CP/CPT/T violation in the system. Method of constraining these parameters has also been discussed.falseDiscrete symmetries | T reversal violationConference Paper18674941813-81520180cpConference Proceeding0
