Search for contact interactions and large extra dimensions in the dilepton mass spectra from proton-proton collisions at \( \sqrt{s}=13 \) TeV

Abstract A search for nonresonant excesses in the invariant mass spectra of electron and muon pairs is presented. The analysis is based on data from proton-proton collisions at a center-of-mass energy of 13 TeV recorded by the CMS experiment in 2016, corresponding to a total integrated luminosity of 36 fb−1. No significant deviation from the standard model is observed. Limits are...

Search for a heavy resonance decaying into a Z boson and a Z or W boson in 2ℓ2q final states at \( \sqrt{s}=13 \) TeV

Abstract A search has been performed for heavy resonances decaying to ZZ or ZW in 2ℓ2q final states, with two charged leptons (ℓ = e, μ) produced by the decay of a Z boson, and two quarks produced by the decay of a W or Z boson. The analysis is sensitive to resonances with masses in the range from 400 to 4500 GeV. Two categories are defined based on the merged or resolved...

Search for narrow and broad dijet resonances in proton-proton collisions at \( \sqrt{s}=13 \) TeV and constraints on dark matter mediators and other new particles

Abstract Searches for resonances decaying into pairs of jets are performed using proton-proton collision data collected at \( \sqrt{s}=13 \) TeV corresponding to an integrated luminosity of up to 36 fb−1. A low-mass search, for resonances with masses between 0.6 and 1.6 TeV, is performed based on events with dijets reconstructed at the trigger level from calorimeter information...

Search for disappearing tracks as a signature of new long-lived particles in proton-proton collisions at \( \sqrt{s}=13 \) TeV

Abstract A search is presented for long-lived charged particles that decay within the CMS detector and produce the signature of a disappearing track. A disappearing track is an isolated track with missing hits in the outer layers of the silicon tracker, little or no energy in associated calorimeter deposits, and no associated hits in the muon detectors. This search uses data...

Measurement of the cross section for top quark pair production in association with a W or Z boson in proton-proton collisions at \( \sqrt{s}=13 \) TeV

Abstract A measurement is performed of the cross section of top quark pair production in association with a W or Z boson using proton-proton collisions at a center-of-mass energy of 13 TeV at the LHC. The data sample corresponds to an integrated luminosity of 35.9 fb−1, collected by the CMS experiment in 2016. The measurement is performed in the same-sign dilepton, three- and...

Measurement of the inelastic proton-proton cross section at \( \sqrt{s}=13 \) TeV

Abstract A measurement of the inelastic proton-proton cross section with the CMS detector at a center-of-mass energy of \( \sqrt{s}=13 \) TeV is presented. The analysis is based on events with energy deposits in the forward calorimeters, which cover pseudorapidities of −6.6 < η < −3.0 and +3.0 < η < +5.2. An inelastic cross section of 68.6 ± 0.5(syst) ± 1.6(lumi) mb is obtained...
