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. [...]

Searches for gamma-ray lines and `pure WIMP' spectra from Dark Matter annihilations in dwarf galaxies with H.E.S.S / H.E.S.S. Collaboration
Dwarf spheroidal galaxies are among the most promising targets for detecting signals of Dark Matter (DM) annihilations. The H.E.S.S. [...]

Dark Sectors 2016 Workshop: Community Report / Alexander, Jim (Cornell U., Phys. Dept.) ; Battaglieri, Marco (INFN, Genoa) ; Echenard, Bertrand (Caltech) ; Essig, Rouven (SUNY, Stony Brook) ; Graham, Matthew (SLAC) ; Izaguirre, Eder (Perimeter Inst. Theor. Phys.) ; Jaros, John (SLAC) ; Krnjaic, Gordan (Fermilab) ; Mardon, Jeremy (Stanford U., Phys. Dept.) ; Morrissey, David (TRIUMF) et al.
This report, based on the Dark Sectors workshop at SLAC in April 2016, summarizes the scientific importance of searches for dark sector dark matter and forces at masses beneath the weak-scale, the status of this broad international field, the important milestones motivating future exploration, and promising experimental opportunities to reach these milestones over the next 5-10 years..

Assessing the performance under ionising radiation of lead tungstate scintillators for EM calorimetry in the CLAS12 Forward Tagger / Fegan, S (Genoa U. ; INFN, Genoa) ; Auffray, E (CERN) ; Battaglieri, M (Genoa U. ; INFN, Genoa) ; Buchanan, E (Glasgow U.) ; Caiffi, B (Genoa U. ; INFN, Genoa) ; Celentano, A (Genoa U. ; INFN, Genoa) ; Colaneri, L (INFN, Rome2 ; Rome U., Tor Vergata) ; D׳Angelo, A (INFN, Rome2 ; Rome U., Tor Vergata) ; De Vita, R (Genoa U. ; INFN, Genoa) ; Dormenev, V (U. Giessen, II. Phys. Inst.) et al.
The well-established technology of electromagnetic calorimetry using Lead Tungstate crystals has recently seen an upheaval, with the closure of one of the most experienced large-scale suppliers of such crystals, the Bogoroditsk Technical Chemical Plant (BTCP), which was instrumental in the development of mass production procedures for PWO-II, the current benchmark for this scintillator. Obtaining alternative supplies of Lead Tungstate crystals matching the demanding specifications of contemporary calorimeter devices now presents a significant challenge to detector research and development programmes..

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. [...]

Dark Sectors and New, Light, Weakly-Coupled Particles / Essig, Rouven (YITP, Stony Brook) ; Jaros, John A. (SLAC) ; Wester, William (Fermilab) ; Hansson Adrian, P. (SLAC) ; Andreas, S. (DESY ; Paris, Inst. Astrophys.) ; Averett, T. (William-Mary Coll.) ; Baker, O. (Yale U.) ; Batell, B. (Chicago U.) ; Battaglieri, M. (INFN, Genoa) ; Beacham, J. (New York U.) et al.
Dark sectors, consisting of new, light, weakly-coupled particles that do not interact with the known strong, weak, or electromagnetic forces, are a particularly compelling possibility for new physics. [...]
