TL;DR: Researchers measured the production cross section of a W boson associated with a charm quark in proton-proton collisions at 13TeV, achieving 1% precision in the cross section ratio Rc±, and compared results with theoretical predictions up to next-to-next-to-leading order in perturbative quantum chromodynamics.

TL;DR: A search for lepton flavor violating τ→3μ decay in proton-proton collisions at 13 TeV is performed using 97.7 fb−1 of CMS data, with no evidence observed, yielding upper limits on the branching fraction of 2.9×10−8 to 3.6×10−8.

Search for Displaced Supersymmetry in Events with an Electron and a Muon with Large Impact Parameters

Vardan Khachatryan, +2127 more

- 13 Feb 2015

- Physical Review Letters

TL;DR: The results are the most restrictive to date on the "displaced supersymmetry" model, with the most stringent limit being obtained for a top squark lifetime corresponding to cτ=2 cm, excluding masses below 790 GeV at 95% confidence level.

Ratios of dijet production cross sections as a function of the absolute difference in rapidity between jets in proton-proton collisions at sqrt(s) = 7 TeV

S. Chatrchyan, +4042 more

- 16 Nov 2012

- European Physical Journal C

TL;DR: In this paper, a study of dijet production in proton-proton collisions was performed at 7 TeV for jets with p > 35 GeV and p < 4.7 using data collected with the CMS detector at the LHC in 2010.
