Transverse momentum dependence of $J/\psi$ and $\psi^{\prime}$ yields in $|y|$ < 0.35, and ${\psi^{\prime}}/{J/\psi}$ ratio together with ratios obtained in other experiments. Uncertainties are point-to-point uncorrelated (uncorr.) (statistical and uncorrelated systematic uncertainties) and correlated systematic (corr.) uncertainties. The global uncertainty is 10%.

The first measurement of dielectron (e + e −) production in central (0 – 10 %) Pb – Pb collisions at √sNN=2.76TeV at the LHC is presented. The dielectron invariant-mass spectrum is compared to the expected contributions from hadron decays in the invariant-mass range 0 < mee < 3.5 GeV / c2. The ratio of data and the cocktail of hadronic contributions without vacuum ρ0 is measured in the invariant-mass range 0.15 < mee < 0.7 GeV / c2, w…
