A search for resonances and quantum black holes is performed using the dijet mass spectra measured in proton-proton collisions at $\sqrt{s}=8\text{ }\text{ }\mathrm{TeV}$ with the CMS detector at the LHC. The data set corresponds to an integrated luminosity of $19.7\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. …

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 …

A search is presented for charge-asymmetric production of a W boson that has been proposed to accommodate the forward-backward asymmetry observed in the production of top-antitop quark pairs at the Tevatron.The new heavy W boson would be produced in association with a …

The ${B}_{s}^{0}$ differential production cross section is measured as functions of the transverse momentum and rapidity in $pp$ collisions at $\sqrt{s}=7\text{ }\text{ }\mathrm{TeV}$, using the ${B}_{s}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\phi}$ decay, and compared with predictions based on perturbative QCD calculations at next-to-leading order. The data sample, …
