 Reconstruction and Selection of Single Top + Higgs to $\mathrm{b}\overline{\mathrm{b}}$ events at CMS in pp Collisions at $\sqrt{s}$ = 13 TeV / Floeh, Kevin Marcel (KIT, Karlsruhe, EKP) /CMS Collaboration The associated production of a single top quark together with a Higgs boson at the LHC can be used to lift the degeneracy regarding the sign of the top quark Yukawa coupling. Therefore, t-channel and tW-channel production where the Higgs boson is decaying into a $\mathrm{b}\overline{\mathrm{b}}$ pair is inspected. [...] CMS-CR-2016-406.- Geneva : CERN, 2016 - 6 p.

 The CMS Level-1 Trigger for LHC Run II / Cadamuro, Luca (Ecole Polytechnique) /CMS Collaboration The Compact Muon Solenoid (CMS) experiment implements a sophisticated two-level online selection system that achieves a rejection factor of nearly $10^5$. During Run~II, the LHC has increased the centre-of-mass energy of proton-proton collisions up to 13 TeV and may progressively reach an instantaneous luminosity of $2\times10^{34}\mbox{cm}^{-2}\mbox{s}^{-1}$ or higher.

 Study of rare B-decays with the CMS experiment / Swain, Sanjay Kumar (Bhubaneswar, NISER) /CMS Collaboration The Flavour Changing Neutral Current decays $B \rightarrow K^{*} \mu^+ \mu^-$ and $B \rightarrow \mu^+ \mu^-$ provide high sensitivity to New Physics contributions. Sensitive observables include the muon forward-backward asymmetry, the fraction of $K^*$ longitudinal polarisation, and the differential branching fraction.

 Upgrades to the CMS Cathode Strip Chamber Electronics for HL-LHC / Morse, David Michael (Northeastern U.) /CMS Collaboration Cathode strip chambers (CSCs) are used to detect muons in theend cap region of the CMS detector. The chambers are arrangedin rings in four planes on each end of the detector. [...] CMS-CR-2016-441.- Geneva : CERN, 2016 - 4 p.

 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.
