The ${Q}_\mathrm{CP}$ of \kstar(red circles) and \phim(blue squares) mesons as a function of $\pt$ for 0--10$\%$ / 40--100$\%$ (top panels) and 10--40$\%$ / 40--100$\%$ (bottom panels) in various rapidity intervals within the range $-$1.2 $<$ $y$ $<$ 0.3 in $\pPb$ collisions at \snn = 5.02 TeV. The statistical and systematic uncertainties are represented by vertical bars and boxes, respectively.
