Query: A novel observable for $C\!P$ violation in multi-body decays and its
  application potential to charm and beauty meson decays   A novel observable measuring the $C\!P$ asymmetry in multi-body decays of
heavy mesons, which is called the forward-backward asymmetry induced $C\!P$
asymmetry (FBI-$C\!P$A), $A_{CP}^{FB}$, is introduced. This observable has the
dual advantages that 1) it can isolate the $C\!P$ asymmetry associated with the
interference of the $S$- and $P$-wave amplitude from that associated with the
$S$- or $P$-wave amplitude alone; 2) it can effectively almost double the
statistics comparing to the conventionally defined regional $C\!P$ asymmetry.
We also suggest to perform the measurements of FBI-$C\!P$A in some three-body
decay channels of charm and beauty mesons.
