Search for strong electric fields in PbPb collisions at ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} = $ 5.02 TeV using azimuthal anisotropy of prompt ${\mathrm{D^0}}$ and ${\mathrm{\overline{D}}{}^0}$ mesons / CMS Collaboration
The strong Coulomb field created in ultrarelativistic heavy ion collisions is expected to produce a rapidity-dependent difference ($\Delta v_{2}$) in the second Fourier coefficient of the azimuthal distribution (elliptic flow, $v_{2}$) between ${\mathrm{D^0}}$ ($\mathrm{\bar{u}}\mathrm{c}$) and ${\mathrm{\overline{D}}{}^0}$ ($\mathrm{u}\mathrm{\bar{c}}$) mesons.
