ATLAS Event Displays from 2010 Heavy Ion Collisions

The event displays below are stand-alone event displays from 2010 Heavy Ion collision data and are approved to be shown by ATLAS speakers at conferences and similar events. Click on the thumbnail images to access full-size displays. Event displays available on the ATLAS outreach pages may also be shown in talks.

Contact Dave Charlton, or the data preparation coordinators, Beate Heinemann and Jamie Boyd, or the event display coordinator, Michael Hauschild, in case of questions. If you wish to use these events for other purposes than presentations of ATLAS results, please see the copyright statement.

Early Heavy Ion Collision Events

Early heavy ion event in first heavy-ion fill with stable beam collisions, 8 November 2010. Raw number of reconstructed tracks with pT > 1 GeV is 1115.

An animated version of this event is also available on the ATLAS multimedia pages.

Another early heavy ion event in first heavy-ion fill with stable beam collisions, 8 November 2010. Raw number of reconstructed tracks with pT >1 GeV is 1025.

Heavy Ion Collisions with Jets - Asymmetric and Symmetric

A highly asymmetric dijet event, with one jet with ET > 100 GeV and no evident recoiling jet, and with high energy calorimeter cell deposits distributed over a wide azimuthal region. Only tracks with pT > 2.6 GeV are shown, and only calorimeter energy deposits with cell energy ET > 700 MeV in the electromagnetic calorimeter, and E > 1 GeV in the hadronic calorimeter. From Observation of a centrality-dependent dijet asymmetry in lead-lead collisions at √sNN = 2.76 TeV with the ATLAS detector at the LHC.

Three more events with asymmetric jets.

A heavy ion collision with two approximately transversely-balanced jets. The event is fairly peripheral.
Another heavy ion collision with two jets. Preliminary estimates of the jet ET's are that they are around 160 GeV.

Heavy Ion Collisions with a J/ψ Candidate

A heavy ion collision with a candidate J/ψ → μ+μ- decay. The two pictures are of the same event. The event passes the selection requirements for J/ψ candidates in Measurement of the centrality dependence of J/ψ yields and observation of Z production in lead-lead collisions with the ATLAS detector at the LHC . The centrality of this event is in the 0-10% bin.

Heavy Ion Collisions with a Z Candidate

A heavy ion collision with a candidate Z → e+e- decay. The three pictures are of the same event. The invariant mass of the dielectron system is ~104 GeV.

A heavy ion collision with a candidate Z → μ+μ- decay. The two muons shown in purple (first display) or red (second display) are the candidates to originate from the Z decay. The transverse momenta of these two muons are 44 and 45 GeV, and the invariant mass of the dimuon system is 93 GeV.
