The LHCb experiment is presented as a use case. A statistical uncertainty of approximately \begin{document}$8^{\circ}-19^{\circ}$\end{document} can be achieved with the \begin{document}$ pp $\end{document} collision data collected in the LHCb experiment from 2011 to 2018. The sensitivity to \begin{document}$ \gamma $\end{document} should be of the order \begin{document}$3^{\circ}-8^{\circ}$\end{document} after accumulating 23 fb-1 of \begin{document}$ pp $\end{document} collision data by 2025, whereas it is expected to improve further by 300 fb-1 by the second half of the 2030 decade. The accuracy is dependent on the strong parameters \begin{document}$ {{r^{(*)}_{B}}} $\end{document} and \begin{document}$ {{\delta^{(*)}_{B}}} $\end{document}, which together with \begin{document}$ \gamma $\end{document}describe the interference between the leading amplitudes of the \begin{document}$ {{B^0_s}}\rightarrow \tilde{D}^{(*)0}\phi $\end{document} decays."> Study of the CKM angle <i>γ</i> sensitivity using flavor untagged <inline-formula><tex-math id="M1">\begin{document}$ {{B^0_s}} {\rightarrow} \tilde{{D}}^{{(*)0}} {\phi} $\end{document}</tex-math><alternatives><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/aa0c3432-98e2-4127-bc01-0714fc7168c4/CPC-2020-0400_M1.jpg"/><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/aa0c3432-98e2-4127-bc01-0714fc7168c4/CPC-2020-0400_M1.png"/></alternatives></inline-formula> decays -
