 Jet fragmentation measurements in p+Pb collisions with ATLAS / Rybar, Martin (University of Illinois at Urbana-Champaign) roton-nucleus collisions have been studied to provide baseline expectations for hard processes in heavy ion collisions. The rates of such processes could be modified compared to the expectation from binary scaled pp reference through nuclear modifications of parton distribution functions.

 Vector Boson Plus Jets Measurements with the ATLAS Detector / Tannenwald, Benjamin Bordy (Ohio State University) The inclusive production of W and Z bosons as well the off­-shell Z/gamma* production are standard candles at hadron colliders. The measurement of their production cross­-sections can be compared to theory calculations at NNLO QCD and have an impact on our knowledge of the parton densities of the proton.

 Centrality dependence of low-$p_{_\text{T}}$ and high-$p_{_\text{T}}$ particle production in proton--lead collisions with ATLAS / Shulga, Evgeny (National Research Nuclear University MEPhI) Measurements of the centrality dependence of low-$p_{_\text{T}}$ and high-$p_{_\text{T}}$ particle production in proton-lead collisions at the LHC can provide unique insight into the dynamics of soft and hard scattering processes and the initial state of ultra-relativistic nuclear collisions. Recent results have shown that both soft and hard processes may be significantly influenced by event-to-event fluctuations (variations) in the structure of the proton.

 New results on inclusive and reaction plane dependent dijet asymmetry in Pb+Pb collisions with ATLAS / Perepelitsa, Dennis (Brookhaven National Laboratory (BNL)) The phenomenon of events containing highly asymmetric dijet pairs is one of the most striking results in heavy ion physics. It has provided the first direct observation of in-medium jet energy loss at the LHC.

 Femtoscopy measurements in p+Pb collisions at $\sqrt{s_{_{\text{NN}}}}$ = 5.02~GeV with ATLAS at the LHC / Kohler, Markus (Weizmann Institute of Science (IL)) Recent measurements in two- and multi-particle correlations in p+Pb collisions suggest collective behavior reminiscent of that observed in Pb+Pb. In addition, the data hint at interesting geometric behavior in ultra-central p+Pb events, where fluctuations in the size of the proton may become significant.

 Measurement of forward-backward multiplicity correlations in PbPb, pPb and pp collisions with the ATLAS detector / Jia, Jiangyong (Stony Brook University) Two-particle pseudorapidity correlations are measured in $\sqrt{s_{\rm{NN}}}$ = 2.76 TeV Pb+Pb, $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV $p$+Pb and $\sqrt{s}$ = 13 TeV $pp$ collisions, with a total integrated luminosity of approximately 7~$\mu\mathrm{b}^{-1}$, 28~$\mathrm{nb}^{-1}$ and 14~$\mathrm{nb}^{-1}$, respectively. The correlation function $C_{\rm N}(\eta_1,\eta_2)$ is measured using charged particles in the pseudorapidity range $|\eta|<2.4$ with transverse momentum $p_T>0.2$ GeV, and it is measured as a function of event multiplicity, defined by the total number of charged particles with $|\eta|<2.5$ and $p_T>0.4$ GeV.

 Measurement of forward-backward multiplicity correlations in lead-lead, proton-lead and proton-proton collisions with the ATLAS detector / Zhou, Mingliang (Stony Brook University) Two-particle pseudo rapidity correlations are measured in $\sqrt{s_{NN}}$ = 2.76 TeV Pb+Pb, $\sqrt{s_{NN}}$=5.02 TeV p+Pb and $\sqrt{s}$ = 13 TeV pp collisions, with total integrated luminosities of approximately 7 μb$^{−1}$, 28 nb$^{−1}$ and 14 nb$^{−1}$, respectively. The correlation function $C_{N}(η_{1},η_{2})$ is measured using charged particles in the pseudo rapidity range |η|<2.4 with transverse momentum $p_{T}$>0.2 GeV, and it is measured as a function of event multiplicity, defined by the total number of charged particles with |η|<2.5 and $p_{T}$>0.4 GeV [...] ATL-PHYS-SLIDE-2015-756.- Geneva : CERN, 2015 - 1 p.

 Observation of long-range elliptic anisotropies in $\sqrt{s}=$13 and 2.76 TeV $pp$ collisions with the ATLAS detector / ATLAS Collaboration ATLAS has measured two-particle correlations as a function of relative azimuthal-angle, Δϕ, and pseudo rapidity, Δη, in $\sqrt{s}$=13 and 2.76 TeV $pp$ collisions at the LHC using charged particles measured in the pseudo rapidity interval |η|<2.5. The correlation functions evaluated in different intervals of measured charged-particle multiplicity show a multiplicity-dependent enhancement at Δϕ∼0 that extends over a wide range of Δη, which has been referred to as the "ridge".

 $R_{\text{AA}}$ and $v_2$ of muons from heavy-quark decays in lead-lead collisions at $\sqrt{s_{_{\text{NN}}}}=2.76$ TeV with the ATLAS detector / Milov, Alexander (Department of Particle Physics, The Weizmann Institute of Science) ATLAS has measured the production of prompt muons in $\sqrt{s_{_{\text{NN}}}}=2.76$ TeV Pb+Pb collisions $\sqrt{s}=2.76$ TeV $pp$ collisions at the LHC. These muons result primarily from semi-leptoinc decays of heavy flavor hadrons.

 Vector boson production in p+Pb and Pb+Pb collisions measured with ATLAS at the LHC / Grabowska-Bold, Iwona (AGH University of Science and Technology, Faculty of Physics and Applied Computer Science, Krakow) Electroweak boson production processes (W, Z and photon) provide access to the earliest moments of heavy ion collisions. Furthermore, because they do not undergo strong interactions, they are sensitive to the initial-state geometry of the collision and potentially the details of the nuclear parton distribution functions (PDF).
