New physics in neutral $\textbf{D}\rightarrow\textbf{VV}$ modes

TL;DR

This paper proposes a model-independent method using time-dependent analysis of neutral D meson decays to VV modes to detect and distinguish new physics effects in decay, mixing, or both, supported by numerical estimates.

Contribution

It introduces a novel, model-independent approach to identify new physics in D meson decays through polarization observables and time-dependent analysis.

Findings

Method can distinguish decay and mixing contributions to new physics

Numerical estimates align with current experimental data

Analysis applicable to various D→VV decay modes

Abstract

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.
