Search for a light pseudoscalar Higgs boson in the boosted μμττ final state in proton-proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2443 more
- 27 Aug 2020 - 
TL;DR: In this paper, a search for a light pseudoscalar Higgs boson (a) decaying from the 125 GeV (or a heavier) scalar (H) boson was performed using the 2016 LHC proton-proton collision data at 13 TeV, corresponding to an integrated luminosity of 35.9 fb−1.
Journal ArticleDOI

Search for Physics Beyond the Standard Model Using Multilepton Signatures in $pp$ Collisions at $s=7$ TeV

S. Chatrchyan, +2176 more
TL;DR: In this paper, a search for physics beyond the standard model in events with at least three leptons and any number of jets is presented, and the results constrain previously unexplored regions of supersymmetric parameter space.
Journal ArticleDOI

Comparison of different approaches to the longitudinal momentum spread after tunnel ionization

Cornelia Hofmann, +4 more
- 13 Mar 2013 - 
TL;DR: In this article, the longitudinal momentum spread resulting from strong-field tunnel ionization of Helium was investigated for all ellipticities of the laser pulse and it was shown that this spread is of the order of twice the transverse momentum spread.
Journal ArticleDOI

Non-Gaussian elliptic-flow fluctuations in PbPb collisions at root S-NN=5.02 TeV

Albert M. Sirunyan, +2301 more
- 10 Feb 2019 - 
TL;DR: In this article, an event-by-event fluctuations in the elliptic-flow coefficient v(2) are studied in PbPb collisions at root S-NN = 5.02 TeV using the CERN LHC.
Journal ArticleDOI

Search for new physics in events with a leptonically decaying Z boson and a large transverse momentum imbalance in proton–proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2257 more
- 11 Apr 2018 - 
TL;DR: In this article, a search for new physics in events with a Z boson produced in association with large missing transverse momentum at the LHC is presented, based on the 2016 data sample of proton-proton collisions recorded with the CMS experiment at s=13TeV, corresponding to an integrated luminosity of 35.9 fb-1.
