Distribution of $m_1^{\mu ^+\mu ^- }$ vs $m_2^{\mu ^+\mu ^- }$ for selected pairs of $ { J \mskip -3mu/\mskip -2mu\psi \mskip 2mu} \rightarrow \mu ^+\mu ^- $ candidates in different $ p_{\mathrm{T}}^{ { J \mskip -3mu/\mskip -2mu\psi \mskip 2mu} } $ regions.

Projections of the extended unbinned maximum likelihood fit to (left) $m_1^{\mu ^+\mu ^- }$ and (right) $m_2^{\mu ^+\mu ^- }$ for $ p_{\mathrm{T}}^{ { J \mskip -3mu/\mskip -2mu\psi \mskip 2mu} } >2\mathrm{ Ge V} $. The total fit function is shown as a solid thick orange line. The solid thin red curve shows the signal component, while the background with one true $ { J \mskip -3mu/\mskip -2mu\psi \mskip 2mu}$ candidate is shown by the dashed magenta line and the pure combinatorial background is shown with a dotted thin blue line.

The uncertainties in the {\sc{Powheg}} and $ Pythia $ predictions due to the choice of factorization and renormalization scales are shown as orange crossdash-hatched and green solid areas, respectively.
