 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.

 Measurement of the prompt $J/\psi$ pair production cross-section in pp collisions at $\sqrt{s} = 8$ TeV with the ATLAS detector The production of two prompt $J/\psi$ mesons, each with transverse momenta $p_{\mathrm{T}}>8.5$ GeV and rapidity $|y| < 2.1$, is studied using a sample of proton-proton collisions at $\sqrt{s} = 8$ TeV, corresponding to an integrated luminosity of 11.4 fb$^{-1}$ collected in 2012 with the ATLAS detector at the LHC.

 Measurement of the $W$ boson polarisation in $t\bar{t}$ events from $pp$ collisions at $\sqrt{s}$ = 8 TeV in the lepton+jets channel with ATLAS / Aaboud, Morad (Oujda U.) ; Aad, Georges (Marseille, CPPM) ; Abbott, Brad (Oklahoma U.) ; Abdallah, Jalal (Texas U., Arlington) ; Abdinov, Ovsat (Baku, Inst. Phys.) ; Abeloos, Baptiste (Orsay, LAL) ; AbouZeid, Ossama (UC, Santa Cruz) ; Abraham, Nicola (Sussex U.) ; Abramowicz, Halina (Tel Aviv U.) ; Abreu, Henso (Technion) et al. /ATLAS This paper presents a measurement of the polarisation of $W$ bosons from $t\bar{t}$ decays, reconstructed in events with one high-$p_{\mbox{T}}$ lepton and at least four jets. Data from $pp$ collisions at the LHC were collected at $\sqrt{s}$ = 8 TeV and correspond to an integrated luminosity of 20.2 fb$^{-1}$. [...] arXiv:1612.02577; CERN-PH-2016-219.- 2016-12-08 - 42.
