Measurement of longitudinal-target-polarization dependent azimuthal asymmetries in SIDIS at COMPASS experiment / Parsamyan, Bakur (CERN ; INFN, Turin ; Turin U.)
Preliminary results obtained by the COMPASS experiment for longitudinal-spin-dependent azimuthal asymmetries in single-hadron muoproduction off protons are presented for the first time. The analysis was carried out on the full data sample collected by COMPASS with longitudinally polarized proton ($NH_3$) target in 2007 and 2011 using 160~\gvc and 200~\gvc muon beams, correspondingly. [...]

First measurement of transverse-spin-dependent azimuthal asymmetries in the Drell-Yan process / Parsamyan, Bakur (CERN)
The COMPASS experiment at CERN, as part of its programme addresses the exploration of the transverse spin structure of the nucleon by measuring spin (in)dependent azimuthal asymmetries in semi-inclusive DIS and, recently, also in Drell-Yan processes. Between 2002 and 2010 COMPASS performed a series of SIDIS measurements, using a longitudinally polarized muon beam impinging on transversely polarized $^6LiD$ or $NH_3$ targets. [...]

A panoramic coded aperture gamma camera for radioactive hotspots localization / Paradiso, V (Mirion Tech., France ; CERN) ; Amgarou, K (CEA Marcoule, Bagnols-sur-Cèze) ; Lanaute, N Blanc De (Mirion Tech., France) ; Schoepff, V (LIST, Saclay) ; Amoyal, G (LIST, Saclay) ; Mahe, C (CEA Marcoule, Bagnols-sur-Cèze) ; Beltramello, O (CERN) ; Liénard, E (Caen U.)
A known disadvantage of the coded aperture imaging approach is its limited field-of-view (FOV), which often results insufficient when analysing complex dismantling scenes such as post-accidental scenarios, where multiple measurements are needed to fully characterize the scene. In order to overcome this limitation, a panoramic coded aperture γ-camera prototype has been developed. [...]

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. [...]
