Figure Caption

Invariant mass distribution of $\mathrm{D^-}\pi^+$pairs in the $10<\pt<14~\mathrm{GeV}/c$ in pp collisions at $\sqrt{s}=13.6~\mathrm{TeV}$.
The signal peak is described using a gaussian function, and the combinatorial background is described with a second order polynomial.
The correlated backgrounds present on the left-side of the invariant mass distribution are described using templates taken from MC simulations obtained using a Kernel Distribution Estimation, and their normalisation is fixed to the signal integral using the relative BR and efficiencies.
