Strategies and performance of the CMS silicon tracker alignment during LHC Run 2
(Elsevier, 2022)
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. ...
A new calibration method for charm jet identification validated with proton-proton collision events at root s=13 TeV
(Springer, 2022)
Many measurements at the LHC require efficient identification of heavy-flavour jets, i.e. jets originating from bottom (b) or charm (c) quarks. An overview of the algorithms used to identify c jets is described and a novel ...
Performance of the CMS muon trigger system in proton-proton collisions at root s=13 TeV
(IOP Publishing, 2022)
The muon trigger system of the CMS experiment uses a combination of hardware and software to identify events containing a muon. During Run 2 (covering 2015-2018) the LHC achieved instantaneous luminosities as high as 2 x ...
Search for Resonances Decaying to Three W Bosons in Proton-Proton Collisions at ps=13 TeV
(American Physical Society, 2022)
A search for resonances decaying into a W boson and a radion, where the radion decays into two W bosons, is presented. The data analyzed correspond to an integrated luminosity of 138 fb???1 recorded in ffiffiproton-proton ...
Search for a W′ boson decaying to a vector-like quark and a top or bottom quark in the all-jets final state at √s = 13 TeV
(Springer, 2022)
A search is presented for a heavy W′ boson resonance decaying to a B or T vector-like quark and a t or a b quark, respectively. The analysis is performed using proton-proton collisions collected with the CMS detector at ...
Identification of hadronic tau lepton decays using a deep neural network
(IOP Publishing, 2022)
new algorithm is presented to discriminate reconstructed hadronic decays of tau leptons (τ h) that originate from genuine tau leptons in the CMS detector against τ h candidates that originate from quark or gluon jets, ...
Measurement of the Higgs boson width and evidence of its off-shell contributions to ZZ production
(Nature Research, 2022)
Since the discovery of the Higgs boson in 2012, detailed studies of its properties have been ongoing. Besides its mass, its width—related to its lifetime—is an important parameter. One way to determine this quantity is to ...
