New physics in neutral $\textbf{D}\rightarrow\textbf{VV}$ modes
  We show that it is possible to construct observables to test the existence of new physics in a model independent way for the $D^0\rightarrow VV$ modes using a time-dependent analysis of the neutral $D$ meson. We show that it is possible to identify whether the NP is due to decay, mixing or a combination of both. We also provide numerical estimates for the polarization amplitudes for the $D^0\rightarrow\overline{K^{*0}}\rho^0$ mode and show that our analysis is consistent with the present data.
