Reconstruction of signal amplitudes in the CMS electromagnetic calorimeter in the presence of overlapping proton-proton interactions

Albert M. Sirunyan, +2276 more
- 01 Oct 2020 - 
TL;DR: In this paper, a template fitting technique for reconstructing the amplitude of signals produced by the lead tungstate crystals of the CMS electromagnetic calorimeter is described, which is designed to suppress the contribution to the signal of the increased number of out-of-time interactions per beam crossing following the reduction of the accelerator bunch spacing from 50 to 25 ns at the start of Run 2 of the LHC.

Search for $\mathrm{t\overline{t}}$H production in the $H\to\mathrm{b\overline{b}}$ decay channel with leptonic $\mathrm{t\overline{t}}$ decays in proton-proton collisions at $\sqrt{s}=$ 13 TeV

Azimuthal correlations for inclusive 2-jet, 3-jet, and 4-jet events in pp collisions at √s=13TeV

Albert M. Sirunyan, +2231 more
- 01 Jul 2018 - 
TL;DR: Azimuthal correlations between the two jets with the largest transverse momenta p_T in inclusive 2-, 3-, and 4-jet events are presented for several regions of the leading jet up to 4TeV in this paper.
Journal ArticleDOI

Search for ZZ resonances in the 2ℓ2ν final state in proton-proton collisions at 13 TeV

Albert M. Sirunyan, +2341 more
- 05 Mar 2018 - 
TL;DR: In this article, a search for heavy resonances decaying to a pair of Z bosons was performed using data collected with the CMS detector at the LHC using data from proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb^(−1).
Journal ArticleDOI
