$m_{\rm ee}$ spectra showing the contribution of prompt heavy-flavour including the non-prompt JPsi decays.
Detail description
$m_{\rm ee}$ spectra showing the contribution of prompt heavy-flavour including the non-prompt JPsi decays.
The templates used for this fit are described here: https://alice-figure.web.cern.ch/node/31218
Fit function: b prompt + c (a charm + (1-a) beauty) and b ( $(1-f_B)$ prompt + $f_B$ non-prompt JPsi ) + c (a charm + (1-a) beauty) in the mass region between 2.1 and 3.1 GeV/$c^2$
Fitted in the DCA range up to 20$\sigma$. a is fixed to the charm/beauty ratio from Run 2 pp cocktail. b,c $\in$ [0,1], $f_B=0.13$
Fit values of the DCAz component have been used here.
