Performance of irradiated thin n-in-p planar pixel sensors for the ATLAS Inner Tracker upgrade / Savić, Natascha (Munich, Max Planck Inst.) ; Beyer, Julien-Christopher (Munich, Max Planck Inst.) ; Hiti, Bojan (Stefan Inst., Ljubljana) ; Kramberger, Gregor (Stefan Inst., Ljubljana) ; La Rosa, Alessandro (Munich, Max Planck Inst.) ; Macchiolo, Anna (Munich, Max Planck Inst.) ; Mandić, Igor (Stefan Inst., Ljubljana) ; Nisius, Richard (Munich, Max Planck Inst.) ; Petek, Martin (Stefan Inst., Ljubljana)
The ATLAS collaboration will replace its tracking detector with new all silicon pixel and strip systems. This will allow to cope with the higher radiation and occupancy levels expected after the 5-fold increase in the luminosity of the LHC accelerator complex (HL-LHC). [...]

Vibration Control Using a Dedicated Inertial Sensor / Balik, Gael (Annecy, LAPP) ; Caron, Bernard (Savoie U. (main)) ; Aimard, Benjamin (Annecy, LAPP) ; Brunetti, Laurent (Annecy, LAPP) ; Deleglise, Guillaume (Annecy, LAPP)
The Compact Linear Collider (CLIC) project is right in the development phase. In this prospect, the main objective of the final focus stabilization is to succeed in damping ground motion vibration at the sub-nanometer scale to avoid any unwanted motion of the two last final focus magnets. [...]

Combining strong signal amplification made possible by Gaseous Electron Multipliers (GEMs) with the high spatial resolution provided by optical readout, highly performing radiation detectors can be realized. An optically read out GEM-based Time Projection Chamber (TPC) is presented. [...]

Measurement of the nuclear modification factor for high- $p_T$ charged hadrons in p +Pb collisions with the ATLAS detector / Balek, Petr (Weizmann Inst.) /ATLAS
The charged hadron spectra in p +Pb and pp collisions at sNN=s=5.02 TeV are measured with the ATLAS experiment at the LHC. The measurements are performed with p +Pb data recorded in 2013 with an integrated luminosity of 25 nb−1 and pp data recorded in 2015 with an integrated luminosity of 28 pb−1 . [...]

D meson nuclear modification factor in PbPb at 5.02 TeV with CMS / Wang, Jing (MIT) /CMS
The measurement of heavy flavour production is a powerful tool to study the properties of the high-density QCD medium created in heavy-ion collisions as heavy quarks are sensitive to the transport properties of the medium and may interact with the QCD matter differently from light quarks. In particular, the comparison between the nuclear modification factors of light- and heavy-flavour particles provides insights into the expected flavour dependence of in-medium parton energy loss.

Factorization of in-medium parton branching beyond the eikonal approximation / Apolinário, Liliana (LIP, Lisbon) ; Armesto, Néstor (Santiago de Compostela U., IGFAE) ; Milhano, José Guilherme (LIP, Lisbon ; CERN) ; Salgado, Carlos A (Santiago de Compostela U., IGFAE)
The description of the in-medium modifications of partonic showers is at the forefront of current theoretical and experimental efforts in heavy-ion physics. The theory of jet quenching, a commonly used alias for the modifications of the parton branching resulting from the interactions with the QGP, has been significantly developed over the last years.

Neutral meson production in pp, p–Pb and Pb–Pb collisions with ALICE at the LHC / Okubo, Tsubasa (Hiroshima U.) /ALICE
The ALICE experiment is mainly devoted to the study of QGP expected to be created in heavy-ion collisions at the LHC. In the early stage of such collisions, partons can be scattered and photons can be produced in energetic hard processes. [...]

Low mass dielectron measurements in pp, p-Pb, and Pb-Pb collisions with ALICE at the LHC / Gunji, T (Tsukuba, Graduate U. Adv. Studies) /ALICE
Low mass dielectrons are important probes of the hot and dense QCD medium created in heavy-ion collisions, since the production of low mass dielectrons is sensitive to the thermodynamical properties of the medium and chiral symmetry restoration in the medium. The ALICE experiment at the LHC has measured low mass dielectrons in pp collisions at $\sqrt{s}$ = 7 TeV and p–Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV to study and disentangle effects due to the cold nuclear matter.

$\pi^0$-hadron correlations in pp and Pb–Pb collisions and $\pi^0$ elliptic flow in Pb–Pb collisions measured at the ALICE experiment / Peng, Xinye (Hua-Zhong Normal U., LQLP ; CCNU, Wuhan, Inst. Part. Phys.) /ALICE
The study of the azimuthal correlation and anisotropy with π0 offers a powerful way to investigate the properties of strongly-interacting matter created in ultra-relativistic heavy-ion collisions. In this talk, we present the measurement of two-particle correlations of π0 trigger particles with associated charged particles versus azimuthal angle difference (Δ φ ) in pp and central Pb–Pb collisions at sNN=2.76 TeV , as well as the measurement of the elliptic flow (v2) of π0 in Pb-Pb collisions at sNN=2.76 TeV at the ALICE experiment.

$D^0$ meson production in pPb and PbPb collisions at $\sqrt {s_{NN}}$ = 5 TeV with LHCb / Zhu, Xianglei (Tsinghua U., Beijing) /LHCb
The LHCb experiment has the unique property to study open heavy flavors in heavy ion interactions in the forward and backward hemisphere, thanks to its forward acceptance 2<η<5 , and the possibility to study proton-lead collisions for both orientations of the beams. In 2015, LHCb also participated successfully for the first time in the lead-lead data-taking. [...]
