Evidence for light-by-light scattering in ultraperipheral PbPb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV / d'Enterria, David
Evidence for light-by-light (LbL) scattering, $\gamma\gamma\to\gamma\gamma$, in ultraperipheral PbPb collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV is reported. [...]

Directional Detection of Light Dark Matter with Polar Materials / Griffin, Sinead (UC, Berkeley ; LBL, Berkeley) ; Knapen, Simon (UC, Berkeley ; LBL, Berkeley) ; Lin, Tongyan (UC, Berkeley ; LBL, Berkeley ; UC, San Diego) ; Zurek, Kathryn M. (UC, Berkeley ; LBL, Berkeley ; CERN)
We consider the direct detection of dark matter (DM) with polar materials, where single production of optical or acoustic phonons gives excellent reach to scattering of sub-MeV DM for both scalar and vector mediators. [...]

Semi-Inclusive Deep Inelastic Scattering in Wandzura-Wilczek-type approximation / Bastami, S. (Connecticut U.) ; Avakian, H. (Jefferson Lab) ; Efremov, A.V. (Dubna, JINR) ; Kotzinian, A. (Yerevan Phys. Inst. ; INFN, Turin) ; Musch, B.U. (Regensburg U.) ; Parsamyan, B. (CERN) ; Prokudin, A. (Jefferson Lab ; Penn State U., Berks-Lehigh Valley) ; Schlegel, M. (New Mexico State U.) ; Schnell, G. (Basque U., Bilbao ; IKERBASQUE, Bilbao ; IKERBASQUE, Bilbao) ; Schweitzer, P. (Connecticut U. ; Tubingen U.) et al.
We present the complete cross-section for the production of unpolarized hadrons in semi-inclusive deep-inelastic scattering up to power-suppressed ${\cal O}(1/Q^2)$ terms in the Wandzura--Wilczek-type approximation which consists in systematically assuming that $\bar{q}gq$--terms are much smaller than $\bar{q}q$--correlators.

Test and characterization of 400 Hamamatsu R5912-MOD photomultiplier tubes for the ICARUS T600 detector / ICARUS Collaboration
ICARUS T600 will become the far detector of the Short Baseline Neutrino program at FNAL (USA), which foresees three liquid argon time projection chambers along the Booster Neutrino Beam line. [...]

Fine-grained calorimeters for experiments at CLIC and FCC-ee / Viazlo, Oleksandr (CERN)
We present optimisation studies for detectors being designed for future $e^+e^−$ colliders such as CLIC and FCC-ee, using particle-flow calorimetry. Surrounding a large silicon tracker volume, a very fine-grained ECAL is envisaged, with 40 Si-W layers and a lateral segmentation of $5\times5~$mm$^2$. [...]

Measurement of the azimuthal anisotropy of charged particles produced in $\sqrt{s_\mathrm{NN}} = 5.02$ TeV Pb+Pb collisions with the ATLAS detector
Measurements of the azimuthal anisotropy in lead-lead collisions at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV are presented using a data sample corresponding to 0.49 $\mathrm{nb}^{-1}$ integrated luminosity collected by the ATLAS experiment at the LHC in 2015. [...]

Search for heavy charged long-lived particles in proton-proton collisions at $\sqrt{s} = 13$ TeV using an ionisation measurement with the ATLAS detector
This Letter presents a search for heavy charged long-lived particles produced in proton--proton collisions at $\sqrt{s} = 13$ TeV at the LHC using a data sample corresponding to an integrated luminosity of 36.1 fb$^{-1}$ collected by the ATLAS experiment in 2015 and 2016. [...]
