 Latest results on Higgs boson $\to\gamma\gamma$ in the CMS experiment / Bakhshiansohi, Hamed (Louvain U.) /CMS Collaboration The photonic decay of the Higgs boson is one of the most prominent decay modes for the observation and measurement of the Higgs boson properties, although its branching fraction is as low as 0.002. The CMS collaboration has analyzed 35.9fb$^{-1}$ of proton-proton collision data delivered by the LHC at a center of mass energy of 13~TeV. [...] CMS-CR-2017-248.- Geneva : CERN, 2017 - 8 p.

 Measurements of the ${\mathrm{p}}{\mathrm{p}}\to \mathrm{Z}\mathrm{Z}$ production cross section and the $\mathrm{Z} \to 4\ell$ branching fraction, and constraints on anomalous triple gauge couplings at $\sqrt{s} =$ 13 TeV Four-lepton production in proton-proton collisions, ${\mathrm{p}}{\mathrm{p}} \to (\mathrm{Z} / \gamma^*)(\mathrm{Z} /\gamma^*) \to 4\ell$, where $\ell =$ e or $\mu$, is studied at a center-of-mass energy of 13 TeV with the CMS detector at the LHC.

 Monodromy inflation at strong coupling: $4\pi$ in the sky / D'Amico, Guido ; Kaloper, Nemanja ; Lawrence, Albion We present a simple effective field theory formulation of a general family of single field flux monodromy models for which strong coupling effects at large field values can flatten the potential and activate operators with higher powers of derivatives.

 Gauge leptoquark as the origin of B-physics anomalies / Di Luzio, Luca (Durham U., IPPP ; Durham U.) ; Greljo, Admir (Zurich U. ; Sarajevo U.) ; Nardecchia, Marco (CERN) The vector leptoquark representation, $U_\mu = (3,1,2/3)$, was recently identified as an exceptional single mediator model to address experimental hints on lepton flavour universality violation in semileptonic $B$-meson decays, both in neutral ($b \to s \mu \mu$) and charged ($b \to c \tau \nu$) current processes.

 Single top-quark production via $tW$, $tZq$, and $s$-channel with ATLAS and CMS / Finelli, Kevin (Sydney U.) Analyses of single top-quark production via $tW$ production, via $tZq$ production, and in the $s$-channel are presented, showing the scope of recent ATLAS and CMS analyses of $pp$ collisions produced at the LHC at $\sqrt{s}=7,8$, and ${13}\,\text{TeV}$.
