$DCA_{ee}^{z}$ spectra in $2.1 < m_{\rm ee} < 2.3$ GeV/$c^2$ including a template fit of prompt, charm, beauty and non-prompt J/$psi$ DCA templates.
Detail description
$DCA_{ee}^{z}$ spectra in $2.1 < m_{\rm ee} < 2.3$ GeV/$c^2$ including a template fit of prompt, charm, beauty and non-prompt J/$psi$ DCA templates
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)
Fitted in the DCA range up to 4$\sigma$. a is fixed to the charm/beauty ratio from Run 2 pp cocktail. b,c $\in$ [0,1]
