The HEP community is approaching an era were the excellent performances of the particle accelerators in delivering collision at high rate will force the experiments to record a large amount of information. The growing size of the datasets could potentially become a limiting factor in the capability to produce scientific results timely and efficiently. [...]

Measurement of associated Z + charm production in proton-proton collisions at $\sqrt{s} = $ 8 TeV / CMS Collaboration
A study of the associated production of a Z boson and a charm quark jet (Z + c), and a comparison to production with a b quark jet (Z + b), in pp collisions at a centre-of-mass energy of 8 TeV are presented. The analysis uses a data sample corresponding to an integrated luminosity of 19.7 fb$^{-1}$, collected with the CMS detector at the CERN LHC. [...]

Pseudorapidity and transverse momentum dependence of flow harmonics in pPb and PbPb collisionsDifferential flow harmonics v_n in pPb and PbPb collisions / CMS Collaboration
Measurements of azimuthal angular correlations are presented for high-multiplicity pPb collisions at $\sqrt{s_{\mathrm{NN}}} = $ 5.02 TeV and peripheral PbPb collisions at $\sqrt{s_{\mathrm{NN}}} = $ 2.76 TeV. The data used in this work were collected with the CMS detector at the CERN LHC. [...]

Study of dijet events with a large rapidity gap between the two leading jets in pp collisions at $\sqrt{s}$ = 7 TeV / CMS Collaboration
Events with no charged particles produced between the two leading jets are studied in proton-proton collisions at $\sqrt{s}$ = 7 TeV. The jets were required to have transverse momentum $p_\mathrm{T}^{\text{jet}}$ > 40 GeV and pseudorapidity 1.5 $<|\eta^{\text{jet}}| <$ 4.7, and to have values of $\eta^{\text{jet}}$ with opposite signs.

Search for supersymmetry with Higgs boson to diphoton decays using the razor variables at $\sqrt{s} = $ 13 TeV / CMS Collaboration
An inclusive search for anomalous Higgs boson production in the diphoton decay channel and in association with at least one jet is presented, using LHC proton-proton collision data collected by the CMS experiment at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 35.9 fb$^{-1}$. The razor variables $M_\mathrm{R}$ and $\mathrm{R}^2$, as well as the momentum and mass resolution of the diphoton system, are used to categorize events into different search regions. [...]

Normalized differential cross sections for top quark pair production are measured in the dilepton (e$^+$e$^-$, $\mu^+\mu^-$, and $\mu^\mp$e$^\pm$) decay channels in proton-proton collisions at a center-of-mass energy of 13 TeV. The measurements are performed with data corresponding to an integrated luminosity of 2.1 fb$^{-1}$ using the CMS detector at the LHC. [...]

Principal-component analysis of two-particle azimuthal correlations in PbPb and pPb collisions at CMS / CMS Collaboration
For the first time a principal-component analysis is used to separate out different orthogonal modes of the two-particle correlation matrix from heavy ion collisions. The analysis uses data from $\sqrt{s_{\mathrm{NN}}} = $ 2.76 TeV PbPb and $\sqrt{s_{\mathrm{NN}}} = $ 5.02 TeV pPb collisions collected by the CMS experiment at the LHC. [...]

Search for natural supersymmetry in events with top quark pairs and photons in pp collisions at $\sqrt{s} =$ 8 TeV / CMS Collaboration
Results are presented from a search for natural gauge-mediated supersymmetry (SUSY) in a scenario in which the top squark is the lightest squark, the next-to-lightest SUSY particle is a bino-like neutralino, and the lightest SUSY particle is the gravitino. The strong production of top squark pairs can produce events with pairs of top quarks and neutralinos, with each bino-like neutralino decaying to a photon and a gravitino. [...]
