Query: Effect of simulating parity-odd observables in high energy heavy ion
  collisions on Balance Functions of charged particles and elliptic flow of
  pions   At the early stage of heavy ion collisions, non-trivial topologies of the
gauge fields can be created resulting in an imbalance of axial charge density
and eventually separation of electric charges along the direction of the
magnetic field produced in such collisions. This process is called the chiral
magnetic effect (CME). In this work we implement such a charge separation at
the partonic level in AMPT for Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV to
study its consequence on experimental observables. We present the effects on
the pion elliptic flow ($v_2$) and the charged particle balance function (BF)
for varying strengths of initial charge separation. We find that the shape of
the balance function is sensitive to the increasing charge separation. $v_2$ of
pion shows a strong decreasing trend at higher transverse momenta ($p_T$) with
increasing charge separation. Charge balance functions show a peak at
$\Delta\phi \sim 180 $ with charge separation implemented in the partonic level
as expected for the parity violation. We have also calculated parity observable
$\gamma$ in the form of BF's moments. $\gamma$ shows a decreasing trend with
charge separation. It has a negative value for charge separation produced by
flipping more than 30 $\%$ of quarks in the parton level. We also notice that
$<\gamma>$ for the same charge correlation and the opposite charge correlation
shows negative and positive values, respectively.
