Particle-flow reconstruction and global event description with the CMS detector

Albert M. Sirunyan, +2215 more
- 06 Oct 2017 - 
TL;DR: A fully-fledged particle-flow reconstruction algorithm tuned to the CMS detector was developed and has been consistently used in physics analyses for the first time at a hadron collider as mentioned in this paper.
Journal ArticleDOI

Search for dark matter, extra dimensions, and unparticles in monojet events in proton–proton collisions at √s = 8 TeV

Vardan Khachatryan, +2122 more
TL;DR: In this paper, a search for particle dark matter (DM), extra dimensions, and unparticles using events containing a jet and an imbalance in transverse momentum was conducted at the LHC.
Journal ArticleDOI

Extraction and validation of a new set of CMS pythia8 tunes from underlying-event measurements

Albert M. Sirunyan, +2251 more
- 03 Jan 2020 - 
TL;DR: For the first time, predictions from pythia8 obtained with tunes based on NLO or NNLO PDFs are shown to reliably describe minimum-bias and underlying-event data with a similar level of agreement to predictions from tunes using LO PDF sets.
Journal ArticleDOI

Search for invisible decays of Higgs bosons in the vector boson fusion and associated ZH production modes

S. Chatrchyan, +2233 more
- 13 Aug 2014 - 
TL;DR: The observed (expected) upper limit on the invisible branching fraction at 0.58 (0.44) is interpreted in terms of a Higgs-portal model of dark matter interactions.
Journal ArticleDOI

Measurement of the elliptic anisotropy of charged particles produced in PbPb collisions at √sNN=2.76 TeV

S. Chatrchyan, +2187 more
- 07 Jan 2013 - 
TL;DR: In this article, the anisotropy of the azimuthal distributions of charged particles produced in √s_(NN)=2.76 TeV PbPb collisions with the CMS experiment at the LHC is studied with the event plane method, two-and fourparticle cumulants, and Lee-Yang zeros.
