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. [...]

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 $19.7~\mathrm{fb}^{-1}$.

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. [...]
