 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 ${13}\,\text{TeV}$.

 Search for diboson resonances decaying into W, Z and H bosons at CMS / Lange, Clemens (CERN) /CMS Collaboration Beyond the standard model theories like extra-dimensions and composite Higgs scenarios predict the existence of very heavy resonances compatible with a spin-0 (radion), spin-1 (W', Z') and spin-2 (graviton) particle with large branching fractions in pairs of standard model bosons and negligible branching fractions to light fermions. We present an overview of searches for new physics containing W, Z or H bosons in the final state, using proton-proton collision data collected with the CMS detector at the CERN LHC.

 Performance and track-based alignment of the Phase-1 upgraded CMS pixel detector / Botta, Valeria (DESY) /CMS Collaboration The Compact Muon Solenoid (CMS) detector is a multi-purpose detector constructed in order to study high-energy particle collisions at the Large Hadron Collider (LHC) at CERN. The all-silicon design of the tracking system of the CMS experiment provided excellent resolution for charged tracks and an efficient tagging of jets during Run 1 and Run 2 of the LHC.
