 R and D on a new type of micropattern gaseous detector the Fast Timing Micropattern detector. / Vai, Ilaria (INFN, Pavia ; Pavia U.) /CMS Collaboration Micropattern gaseous detectors (MPGD) underwent significant upgrades in recent years, introducing resistive materials to build compact spark-protected devices. Exploiting this technology further, various features such as space and time resolution, rate capability, sensitive area, operational stability and radiation hardness can be improved.

 Search for the production of vector-like quarks at CMS / Hogan, Julie Managan (Brown U.) /CMS Collaboration Three recent searches are presented for electroweak production of a vector-like top quark partner T of charge 2e/3 in association with a standard model top or bottom quark, using 2 3 fb-1 of proton-proton collision data at sqrt(s) = 13 TeV collected by the CMS experiment at the CERN LHC. The searches, the first of their kind at this energy, are targeted to three decay modes of the T quark tH, in a fully hadronic final state; tZ, in a dilepton final state; and bW, in a single lepton final state.

(Dubna, JINR ; CTU, Prague) et al. /COMPASS Final results are presented from the inclusive measurement of deep-inelastic polarised-muon scattering on longitudinally polarised deuterons using a $^6$LiD target. The data were taken at $160~{\rm GeV}$ beam energy and the results are shown for the kinematic range $1~({\rm GeV}/c)^2 < Q^2 < 100~({\rm GeV}/c)^2$ in photon virtuality, $0.004 4~{\rm GeV}/c^2$ in the mass of the hadronic final state.
