Transverse-target-spin asymmetry in exclusive $\omega$-meson electroproduction / HERMES Collaboration
Hard exclusive electroproduction of $\omega$ mesons is studied with the HERMES spectrometer at the DESY laboratory by scattering 27.6 GeV positron and electron beams off a transversely polarized hydrogen target. The amplitudes of five azimuthal modulations of the single-spin asymmetry of the cross section with respect to the transverse proton polarization are measured. [...]

Search for heavy neutral lepton production in $K^+$ decays / NA62 Collaboration
A search for heavy neutral lepton production in $K^+$ decays using a data sample collected with a minimum bias trigger by the NA62 experiment at CERN in 2015 is reported. Upper limits at the $10^{-7}$ to $10^{-6}$ level are established on the elements of the extended neutrino mixing matrix $|U_{\ell 4}|^2$ ($\ell=e,\mu$) for heavy neutral lepton mass in the range $170-448~{\rm MeV}/c^2$.

Technical Design Report for the: PANDA Straw Tube Tracker / PANDA Collaboration
This document describes the technical layout and the expected performance of the Straw Tube Tracker (STT), the main tracking detector of the PANDA target spectrometer. The STT encloses a Micro-Vertex-Detector (MVD) for the inner tracking and is followed in beam direction by a set of GEM-stations. [...]

Measurement of the high-energy gamma-ray emission from the Moon with the Fermi Large Area Telescope / Fermi LAT Collaboration
We have measured the gamma-ray emission spectrum of the Moon using the data collected by the Large Area Telescope onboard the Fermi satellite during its first 7 years of operation, in the energy range from 30 MeV up to a few GeV. We have also studied the time evolution of the flux, finding a correlation with the solar activity. [...]

(Annecy, LAPP) et al. /ECFA/DESY Linear Collider Physics Working Group
We describe the physics potential of $e^+e^-$ linear colliders in this report. These machines are planned to operate in the first phase at a center-of --mass energy of 500 GeV, before being scaled up to about 1 TeV. [...]

Strong enhancement of electromagnetic shower development induced by high-energy photons in a thick oriented tungsten crystal / Soldani, M. (INFN, Ferrara ; Ferrara U.) ; Bandiera, L.

(Catania U. ; INFN, Milan) ; Charitonidis, N. (CERN) ; D'Alessandro, G.L. (CERN) ; De Salvador, D. (INFN, Legnaro ; Padua U.) et al.
We have observed a significant enhancement in the energy deposition by $25$--$100~\mathrm{GeV}$ photons in a $1~\mathrm{cm}$ thick tungsten crystal oriented along its $\langle 111 \rangle$ lattice axes. At $100~\mathrm{GeV}$, this enhancement, with respect to the value observed without axial alignment, is more than twofold. [...]

Coded masks for imaging of neutrino events / NU@FNAL Collaboration
The capture of scintillation light emitted by liquid Argon and Xenon under molecular excitations by charged particles is still a challenging task. Here we present a first attempt to design a device able to grab sufficiently high luminosity in order to reconstruct the path of ionizing particles. [...]

Photoproduction of the $f_2(1270)$ meson using the CLAS detector / CLAS Collaboration
The quark structure of the $f_2(1270)$ meson has, for many years, been assumed to be a pure quark-antiquark ($q\bar{q}$) resonance with quantum numbers $J^{PC} = 2^{++}$. Recently, it was proposed that the $f_2(1270)$ is a molecular state made from the attractive interaction of two $\rho$-mesons. [...]
