Leptonic observables in $\sqrt{s_{NN}}=2.76$~TeV Pb+Pb collisions measured with the ATLAS detector at the LHC
We report on the first measurements of $J/\psi$, $W$ and $Z$ boson production in lead-lead collisions measured by the ATLAS detector at the nucleon-nucleon centre of mass energy $\sqrt{s_{NN}} = 2.76$~TeV. These measurements are done via $J/\psi$ and electroweak boson decays to muon final states. We...

description | We report on the first measurements of $J/\psi$, $W$ and $Z$ boson production in lead-lead collisions measured by the ATLAS detector at the nucleon-nucleon centre of mass energy $\sqrt{s_{NN}} = 2.76$~TeV. These measurements are done via $J/\psi$ and electroweak boson decays to muon final states. We present a measurement of $W$ bosons yields produced in heavy ion collisions as function of centrality, ratios of $W^+/W^−$ and $W/Z$. For a subset of the $W \to \mu \mu$ decays, we report on muon rapidity and charge asymmetry measurements. These measurements are the first ATLAS results on $W$ measurements in lead-lead collisions at the LHC. |
