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

open access: yes, 2017
The CMS apparatus was identified, a few years before the start of the LHC operation at CERN, to feature properties well suited to particle-flow (PF) reconstruction: a highly-segmented tracker, a fine-grained electromagnetic calorimeter, a hermetic hadron

Identification of heavy-flavour jets with the CMS detector in pp collisions at 13 TeV [PDF]

open access: yesJournal of Instrumentation, 2017
Many measurements and searches for physics beyond the standard model at the LHC rely on the efficient identification of heavy-flavour jets, i.e. jets originating from bottom or charm quarks.

Electron and photon reconstruction and identification with the CMS experiment at the CERN LHC [PDF]

open access: yesJournal of Instrumentation, 2020
The performance is presented of the reconstruction and identification algorithms for electrons and photons with the CMS experiment at the LHC. The reported results are based on proton-proton collision data collected at a center-of-mass energy of 13 TeV ...

CM periods, CM regulators and hypergeometric functions, II [PDF]

open access: yesMathematische Zeitschrift, 2017
AbstractWe prove the Gross–Deligne conjecture on CM periods for motives associated with H2 of certain surfaces fibered over the projective line. Then we prove for the same motives a formula which expresses the K1-regulators in terms of hypergeometric functions 3F2, and obtain a new example of non-trivial regulators.

Pileup mitigation at CMS in 13 TeV data [PDF]

open access: yesJournal of Instrumentation, 2020
With increasing instantaneous luminosity at the LHC come additional reconstruction challenges. At high luminosity, many collisions occur simultaneously within one proton-proton bunch crossing. The isolation of an interesting collision from the additional"

Strategies and performance of the CMS silicon tracker alignment during LHC Run 2 [PDF]

open access: yesNuclear Instruments and Methods in Physics Research Section A : Accelerators, Spectrometers, Detectors and Associated Equipment, 2021
The strategies for and the performance of the CMS silicon tracking system alignment during the 2015-2018 data-taking period of the LHC are described. The alignment procedures during and after data taking are explained.

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

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
New sets of CMS underlying-event parameters (“tunes”) are presented for the pythia8 event generator. These tunes use the NNPDF3.1 parton distribution functions (PDFs) at leading (LO), next-to-leading (NLO), or next-to-next-to-leading (NNLO) orders in ...

Search for Higgs boson decays into Z and J/$ψ$ and for Higgs and Z boson decays into J/$ψ$ or $Υ$ pairs in pp collisions at $\sqrt{s}$ = 13 TeV [PDF]

open access: yes, 2022
Data availability Release and preservation of data used by the CMS Collaboration as the basis for publications is guided by the CMS policy as stated in “CMS data preservation, re-use and open access policy” (https://cms-docdb.cern.ch/cgi-bin/PublicDocDB/

Estimation of combining ability and heterosis for yield and its component traits for identification of promising red rice (Oryza sativa L.) hybrids developed from new WA-based CMS lines and red kernel breeding lines

open access: yesElectronic Journal of Plant Breeding, 2022
Combining ability analysis and heterosis enables plant breeders in anticipating improvement in productivity through hybridization and selection. In this study, line × tester mating design was used to develop 42 red rice hybrids by utilizing newly ...
