Electron-beam energy reconstruction for neutrino oscillation measurements / CLAS Collaboration
Neutrinos exist in one of three types or ‘flavours’—electron, muon and tau neutrinos—and oscillate from one flavour to another when propagating through space. This phenomena is one of the few that cannot be described using the standard model of particle physics (reviewed in ref. 1), and so its experimental study can provide new insight into the nature of our Universe (reviewed in ref. 2).

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. [...]

The CLAS12 Geant4 simulation / Ungaro, M (Jefferson Lab) ; Angelini, G (George Washington U.) ; Battaglieri, M (INFN, Genoa) ; Burkert, V D (Jefferson Lab) ; Carman, D S (Jefferson Lab) ; Chatagnon, P (Orsay, IAS) ; Contalbrigo, M (INFM, Ferrara) ; Defurne, M (IRFU, Saclay) ; De Vita, R (INFN, Genoa) ; Duran, B (Temple U.) et al.
The Geant4 Monte-Carlo (GEMC) package is used to simulate the passage of particles through the various CLAS12 detectors. The geometry is implemented through a database of Geant4 volumes created either through the GEMC native API, by the CLAS12 geometry service, or imported from the CAD engineering model. [...]

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..
