Results are reported from a search for physics beyond the standard model in proton-proton collision events with a charged lepton (electron or muon), two jets identified as originating from a bottom quark decay, and significant imbalance in the transverse momentum. The search was performed using a data sample corresponding to 35 fb$^{-1}$, collected by the CMS experiment in 2016 at $\sqrt{s} = 13$ TeV Events with this signature can arise, for example, from the electroweak...

Prompt charmonia production and polarization at LHC in the NRQCD with $k_T$-factorization. Part III: $J/\psi$ meson

S. P. Baranov & A. V. Lipatov
In the framework of $k_T$-factorization approach, the production and polarization of prompt J/ψ mesons at the LHC energies is studied. Our consideration is based on the non-relativistic QCD formalism for bound states and off-shell amplitudes for hard partonic subprocesses. Both the direct production mechanism and feed-down contributions from $χ_c$ and ψ(2S) decays are taken into account. The transverse momentum dependent (or unintegrated) gluon densities in a proton were derived from Ciafaloni-Catani-Fiorani-Marchesini evolution equation or, alternatively,...

Electroweak Precision Measurements and Direct Higgs Searches at the Tevatron.

David Waters
The latest electroweak precision measurements and direct Higgs boson search results from the Tevatron are reviewed. Emphasis is placed on measurements for which the Tevatron is still competitive with the LHC. In the case of certain results, notably the precision measurements of the $W$ boson and top quark masses, the Tevatron results will remain world leading for a considerable period of time.

This paper presents a study of the production of $WW$ or $WZ$ boson pairs, with one $W$ boson decaying to $e\nu$ or $\mu\nu$ and one $W$ or $Z$ boson decaying hadronically. The analysis uses 20.2 fb$^{-1}$ of $\sqrt{s}=8$ TeV $pp$ collision data, collected by the ATLAS detector at the Large Hadron Collider. Cross-sections for $WW/WZ$ production are measured in high-$p_{T}$ fiducial regions defined close to the experimental event selection. The cross-section is measured for the...
