In tagged cascade decays of the type ${P}^{0}({P}^{0})\ensuremath{\rightarrow}{M}^{0}/{M}^{0}\stackrel{\ensuremath{\rightarrow}}{X}\mathrm{fX}$ there are two complex $\mathrm{CPT}$-violating parameters: one in ${P}^{0}\ensuremath{-}{P}^{0}$ mixing, the other one in ${M}^{0}\ensuremath{-}{M}^{0}$ mixing. I analyze these decays and find that, in principle, the former parameter can be extracted from a careful comparison of their time dependences. $\mathrm{CPT}$ violation in …
