$CP$-violating asymmetries from the decay-time distribution of prompt $D^0 \to K^+K^-$ and $D^0 \to \pi^+\pi^-$ decays in the full LHCb Run~1 data sample /LHCb Collaboration
Time-dependent $CP$ asymmetries in the decay rates of the singly Cabibbo-suppressed decays $D^0 \to K^+K^-$ and $D^0 \to \pi^+\pi^-$ are measured in $pp$ collision data at centre-of-mass energies of $7$ and $8\,\mathrm{TeV}$ collected by the LHCb detector, corresponding to an integrated luminosity of $3\,\mathrm{fb}^{-1}$. The strong-interaction decay $D^{*+} \to D^0\pi^+$ is used to infer the flavour of the $D^0$ mesons at production. [...]

Search for long-lived charged particles in proton-proton collisions at $\sqrt{s}=$ 13 TeV / CMS Collaboration
Results are presented of a search for heavy stable charged particles produced in proton-proton collisions at $\sqrt{s} =$ 13 TeV using a data sample corresponding to an integrated luminosity of 2.5 fb$^{-1}$ collected in 2015 with the CMS detector at the CERN LHC. [...]

Sivers asymmetry extracted in SIDIS at the hard scale of the Drell-Yan process at COMPASS / COMPASS Collaboration
Proton transverse-spin azimuthal asymmetries are extracted from the COMPASS 2010 semi-inclusive hadron measurements in deep inelastic muon-nucleon scattering in those four regions of the photon virtuality $Q^2$, which correspond to the four regions of the di-muon mass $\sqrt{Q^2}$ used in the ongoing analysis of the COMPASS Drell-Yan measurements.

Run 1 Higgs legacy combination / Donato, Silvio (INFN, Pisa ; Pisa, Scuola Normale Superiore) /ATLAS and CMS Collaborations
The discovery of the Higgs boson has been an important success of the LHC Run 1. This document presents the combination of the ATLAS and CMS measurements of the Higgs boson production and decay rates and of the Higgs boson coupling with vector bosons and fermions. [...]

Collectivity of strange hadrons in small and large colliding systems with CMS / Stephans, George Stewart (MIT) /CMS Collaboration
Observation of a long-range, near-side, two-particle correlation (known as the ``Ridge") in high-multiplicity pp and pPb collisions opened up new opportunities of exploring novel QCD dynamics in small collision systems. CMS has excellent capabilities of reconstructing weakly decay strange hadrons such as $K^0_s$, $\Lambda$ and $\Xi^-$. [...]

Higgs boson production at the CMS experiment / Choudhury, Somnath (Bhubaneswar, Inst. Phys.) /CMS Collaboration
After the discovery of the Higgs boson, the ATLAS and CMS experiments have performed combined measurements of the mass of the Higgs boson and also measurements of the production and decay rates, as well as constraints on its couplings to vector bosons and fermions. These combined LHC measurements from the proton-proton collision Run-1 data will be summarized. [...]

Squark/gluino searches in hadronic channels with CMS / Sakuma, Tai (Bristol U.) /CMS Collaboration
These proceedings summarize the results of four analyses which searched for squarks and gluinos in hadronic final states with missing transverse momentum in 2.3~fb$^{-1}$ of data in proton-proton collisions at $\sqrt{s}=13$~TeV collected in the year 2015 with the CMS detector at the CERN LHC. Each analysis is characterized by a different kinematic variable that is sensitive to the presence of invisible particles, e.g., $M_\text{T2}$, $\alpha_{\text{T}}$, and \textit{razor} variables.
