Fit to the invariant mass distribution of $\mathrm{D}^{*}$ candidates in $10<p_{\mathrm{T}}<20\ \mathrm{GeV}/c$ interval with different non-prompt fraction for $cos\theta^*$ integrated in pp collisions at $\sqrt{s}=13.6\ \mathrm{TeV}/c$, reconstructed in the $\mathrm{D}^{*} \rightarrow\mathrm{D}^{0}\pi^+ \rightarrow \mathrm{K}^-\pi^+\pi^+$ decay channel. The fit function is composed of a expopowext function to describe the background, Double crystal ball function to describe the $\mathrm{D}^{*}$ peak. Top panel show the helicity frame and bottom panel show the production frame.
