Query: Event-by-event charge separation in Pb-Pb collisions at $\sqrt{s_{\rm
  NN}}$ = 2.76 TeV with ALICE at the LHC   Relativistic heavy-ion collisions provide a unique opportunity to search for
parity violation in non-central collisions. This could lead to charge
separation perpendicular to the reaction plane. An event-by-event measurement
of charge separation effect in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76
TeV using Sliding Dumbbell Method (SDM) is discussed in this article.
