Search for dark matter and unparticles in events with a Z boson and missing transverse momentum in proton-proton collisions at √s=13 TeV

Albert M. Sirunyan, +2311 more
- 10 Mar 2017 - 
TL;DR: In this paper, a search for dark matter and unparticle production at the LHC has been performed using events containing two charged leptons (electrons or muons), consistent with the decay of a Z boson, and large missing transverse momentum.
Journal ArticleDOI

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

Vardan Khachatryan, +2281 more
- 12 Jan 2017 - 
TL;DR: A first search for pair production of dark matter candidates through vector boson fusion in proton-proton collisions at sqrt[s]=8 TeV is performed, with the observed dijet mass spectrum is consistent with the standard model expectation.
Journal ArticleDOI

Search for a heavy resonance decaying to a pair of vector bosons in the lepton plus merged jet final state at s√=13 TeV

Albert M. Sirunyan, +2389 more
- 26 Feb 2018 - 
TL;DR: In this article, a search for a new heavy particle decaying to a pair of vector bosons (WW or WZ) is presented using data from the CMS detector corresponding to an integrated luminosity of 35.9 fb−1 collected in proton-proton collisions at a centre-of-mass energy of 13 TeV in 2016.
Journal ArticleDOI

Search for supersymmetry with razor variables in pp collisions at sqrt(s) = 7 TeV

S. Chatrchyan, +2222 more
TL;DR: In this article, a shape analysis performed in the plane of two kinematic variables, denoted M_R and R^2, that correspond to the mass and transverse energy flow, respectively, of pair-produced, heavy, new-physics particles is presented.
Journal ArticleDOI

Bose-Einstein correlations in pp, pPb, and PbPb collisions at root s(NN)=0.9-7 TeV

Albert M. Sirunyan, +2384 more
- 14 Jun 2018 - 
TL;DR: In this paper, Bose-Einstein correlations are measured in pPb and peripheral PbPb collisions at nucleon-nucleon center-of-mass energies of 5.02 and 2.76 TeV, respectively, using the CMS detector at the Large Hadron Collider.
