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. [...]
