Inclusive search for supersymmetry using razor variables in pp collisions at s =13 TeV
(2017-01-06)
An inclusive search for supersymmetry using razor variables is performed in events with four or more jets and no more than one lepton. The results are based on a sample of proton-proton collisions corresponding to an ...
Search for high-mass diphoton resonances in proton–proton collisions at 13 TeV and combination with 8 TeV search
(2017-05-10)
A search for the resonant production of high-mass photon pairs is presented. The search focuses on spin-0 and spin-2 resonances with masses between 0.5 and 4.5 TeV, and with widths, relative to the mass, between 1.4×10−4 ...
Search for Dark Matter and Supersymmetry with a Compressed Mass Spectrum in the Vector Boson Fusion Topology in Proton-Proton Collisions at s =8 TeV
(2017-01-12)
A first search for pair production of dark matter candidates through vector boson fusion in proton-proton collisions at s=8 TeV is performed with the CMS detector. The vector boson fusion topology enhances missing transverse ...
Measurements of differential cross sections for associated production of a W boson and jets in proton-proton collisions at s =8 TeV
