Erratum to: Search for heavy Higgs bosons decaying to a top quark pair in proton-proton collisions at $$ \sqrt{s} $$ = 13 TeV

A. M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

A search is presented for additional scalar (H) or pseudoscalar (A) Higgs bosons decaying to a top quark pair in proton-proton collisions at a center-of-mass energy of 13 TeV. The data set analyzed corresponds to an integrated luminosity of 35.9 fb−1 collected …

Pileup mitigation at CMS in 13 TeV data

Albert M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

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 "pileup" collisions is needed for effective physics performance.In the CMS Collaboration, several …

Studies of Charm Quark Diffusion inside Jets Using Pb-Pb and pp Collisions at sNN=5.02 TeV

A. M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

The first study of charm quark diffusion with respect to the jet axis in heavy ion collisions is presented. The measurement is performed using jets with p_{T}^{jet}>60 GeV/c and D^{0} mesons with p_{T}^{D}>4 GeV/c in lead-lead (Pb-Pb) and proton-proton (pp) collisions at …

Measurement of $$\hbox {t}{\bar{\hbox {t}}}$$ normalised multi-differential cross sections in $${\text {p}}{\text {p}} $$ collisions at $$\sqrt{s}=13\,{\text {TeV}} $$, and simultaneous determination of the strong coupling strength, top quark pole mass, and parton distribution functions

A. M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

Abstract Normalised multi-differential cross sections for top quark pair ( $$\hbox {t}{\bar{\hbox {t}}}$$ tt¯ ) production are measured in proton-proton collisions at a centre-of-mass energy of 13 $$\,{\text {TeV}}$$ TeV using events containing two oppositely charged leptons. The analysed data were recorded …

Search for charged Higgs bosons decaying into a top and a bottom quark in the all-jet final state of pp collisions at $$ \sqrt{s} $$ = 13 TeV

Albert M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

Abstract A search for charged Higgs bosons (H±) decaying into a top and a bottom quark in the all-jet final state is presented. The analysis uses LHC proton-proton collision data recorded with the CMS detector in 2016 at $$ \sqrt{s} $$ s …

Identification of heavy, energetic, hadronically decaying particles using machine-learning techniques

Albert M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

Machine-learning (ML) techniques are explored to identify and classify hadronic decays of highly Lorentz-boosted W/Z/Higgs bosons and top quarks.Techniques without ML have also been evaluated and are included for comparison.The identification performances of a variety of algorithms are characterized in simulated events …
