Detail description

Fit function (Eq.~\ref{eq:ThreeComponentFunc}), its individual components and dielectron invariant-mass spectra measured in central collisions for the transverse-momentum intervals $2<p_{\mathrm{T}, \mathrm{ee}}<4\ \mathrm{GeV}/\textit{c}$. The hadronic cocktail is $f_{\mathrm{LF}} (m_{\mathrm{ee}}) + f_{\mathrm{HF}} (m_{\mathrm{ee}})$.
