Search for two Higgs bosons in final states containing two photons and two bottom quarks in proton-proton collisions at 8 TeV

Vardan Khachatryan, +2279 more

- 29 Sep 2016

- Physical Review D

TL;DR: In this article, a search for the production of two Higgs bosons in final states containing two photons and two bottom quarks is presented, and upper limits are set at 95% confidence level on the production cross section of new particles and compared to the prediction for the existence of a warped extra dimension.

- 15 May 2018

- Journal of High Energy Physics

TL;DR: In this article, a search in energetic, high-multiplicity final states for evidence of physics beyond the standard model, such as black holes, string balls, and electroweak sphalerons, is presented.

Search for new physics in dijet angular distributions using proton–proton collisions at √s=13TeV and constraints on dark matter and other models

Albert M. Sirunyan, +2298 more

- 21 Mar 2018

- European Physical Journal C

TL;DR: A search is presented for physics beyond the standard model, based on measurements of dijet angular distributions in proton–proton collisions at s=13TeV, and the observed distributions are found to be in agreement with predictions from perturbative quantum chromodynamics that include electroweak corrections.

Measurement of the t t ¯ production cross section using events with one lepton and at least one jet in pp collisions at √s=13 TeV

Albert M. Sirunyan, +2328 more

- 22 Jan 2017

- Journal of High Energy Physics

TL;DR: In this paper, a measurement of the tt production cross section at √s = 13 TeV was presented using proton-proton collisions, corresponding to an integrated luminosity of 2.2 fb^(−1), collected with the CMS detector at the LHC.
