Study of Z production in PbPb and pp collisions at $\sqrt{s_{NN}}$ = 2.76 TeV in the dimuon and dielectron decay channels / CMS Collaboration
The production of Z bosons is studied in the dimuon and dielectron decay channels in PbPb and pp collisions at $\sqrt{s_{\mathrm{NN}}}$ = 2.76 TeV, using data collected by the CMS experiment at the LHC. The PbPb data sample corresponds to an integrated luminosity of about $150~\mu\mathrm{b}^{-1}$, while the pp data sample collected in 2013 at the same nucleon-nucleon centre-of-mass energy has an integrated luminosity of $5.4~\mathrm{pb}^{-1}$.

Identification techniques for highly boosted W bosons that decay into hadrons / CMS Collaboration
In searches for new physics in the energy regime of the LHC, it is becoming increasingly important to distinguish single-jet objects that originate from the merging of the decay products of W bosons produced with high transverse momenta from jets initiated by single partons. Algorithms are defined to identify such W jets for different signals of interest, using techniques that are also applicable to other decays of bosons to hadrons that result in a single jet, such as those from highly boosted Z and Higgs bosons.

Measurement of electroweak production of two jets in association with a Z boson in proton-proton collisions at $\sqrt{s}=8~\mathrm{TeV}$ / CMS Collaboration
The purely electroweak (EW) cross section for the production of two jets in association with a Z boson, in proton-proton collisions at $\sqrt{s}=8~\mathrm{TeV}$, is measured using data recorded by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of $19.7~\mathrm{fb}^{-1}$. The electroweak cross section for the $\ell \ell \mathrm{jj}$ final state (with $\ell$ = e or $\mu$ and $\mathrm{j}$ representing the quarks produced in the hard interaction) in the kinematic region defined by $M_{\ell\ell}$ > $50~\mathrm{GeV}$, $M_\mathrm{jj}$ > $120~\mathrm{GeV}$, transverse momentum $p_{\mathrm{Tj}}$ > $25~\mathrm{GeV}$, and pseudorapidity $|\eta_\mathrm{j}|$ < $5$, is found to be $\sigma_\mathrm{EW}(\ell\ell \mathrm{jj}) =174 \pm 15~\mathrm{(stat)} \pm 40~\mathrm{(syst)}~\mathrm{fb}$, in agreement with the standard model prediction.The associated jet activity of the selected events is studied, in particular in a signal-enriched region of phase space, and the measurements are found to be in agreement with QCD predictions..

Searches for heavy Higgs bosons in two-Higgs-doublet models and for $t→ch$ decay using multilepton and diphoton final states in $pp$ collisions at 8 TeV / CMS Collaboration
Searches are presented for heavy scalar ($\mathrm{H}$) and pseudoscalar ($\mathrm{A}$) Higgs bosons posited in the two doublet model (2HDM) extensions of the standard model (SM). These searches are based on a data sample of $\mathrm{p}\mathrm{p}$ collisions collected with the CMS experiment at the LHC at a center-of-mass energy of $\sqrt{s} = 8~\mathrm{TeV}$ and corresponding to an integrated luminosity of $19.5~\mathrm{fb}^{-1}$.

Measurement of prompt $\psi(2\mathrm{S})$ to $\mathrm{J}/\psi$ yield ratios in $\mathrm{Pb}\mathrm{Pb}$ and $\mathrm{p}\mathrm{p}$ collisions at $\sqrt{s_\mathrm{NN}} = 2.76~\mathrm{TeV}$ / CMS Collaboration
The ratio between the prompt $\psi(2\mathrm{S})$ and $\mathrm{J}/\psi$ yields, reconstructed via their decays into $\mu^+\mu^-$, is measured in $\mathrm{Pb}\mathrm{Pb}$ and $\mathrm{p}\mathrm{p}$ collisions at $\sqrt{s_\mathrm{NN}} = 2.76~\mathrm{TeV}$. The analysis is based on $\mathrm{Pb}\mathrm{Pb}$ and $\mathrm{p}\mathrm{p}$ data samples collected by CMS at the LHC, corresponding to integrated luminosities of $150~\mu\mathrm{b}^{-1}$ and $5.4~\mathrm{pb}^{-1}$, respectively.

Measurement of the W boson helicity in events with a single reconstructed top quark in pp collisions at $\sqrt{s}$ = 8 TeV / CMS Collaboration
A measurement of the W boson helicity is presented, where the W boson originates from the decay of a top quark produced in pp collisions. The event selection, optimized for reconstructing a single top quark in the final state, requires exactly one isolated lepton (muon or electron) and exactly two jets, one of which is likely to originate from the hadronization of a bottom quark.

Search for monotop signatures in proton-proton collisions at $\sqrt{s}$ =8 TeV / CMS Collaboration
Results are presented from a search for new decaying massive particles whose presence is inferred from an imbalance in transverse momentum and which are produced in association with a single top quark that decays into a bottom quark and two light quarks. The measurement is performed using 19.7 fb$^{-1}$ of data from proton-proton collisions at a center-of-mass energy of 8 TeV, collected with the CMS detector at the CERN LHC. [...]

Measurement of the production cross section ratio $\sigma(\chi_{b2}(1\mathrm{P}))/ \sigma(\chi_{b1}(1\mathrm{P}))$ in pp collisions at $\sqrt{s}$ = 8 TeV / CMS Collaboration
A measurement of the production cross section ratio $\sigma(\chi_{b2}(1\mathrm{P}))/ \sigma(\chi_{b1}(1\mathrm{P}))$ is presented. The $\chi_{b1}(1\mathrm{P})$ and $\chi_{b2}(1\mathrm{P})$ bottomonium states, promptly produced in pp collisions at $\sqrt{s}$= 8 TeV, are detected by the CMS experiment at the CERN LHC through their radiative decays $\chi_{b1,2}(1\mathrm{P}) \rightarrow \Upsilon(1\mathrm{S}) + \gamma$.
