Combination of inclusive top-quark pair production cross-section measurements using ATLAS and CMS data at √s = 7 and 8 TeV
(Springer, 2023-07-27)
A combination of measurements of the inclusive top-quark pair production cross-section performed by ATLAS and CMS in proton-proton collisions at centre-of-mass energies of 7 and 8TeV at the LHC is presented. The cross-sections ...
Measurement of the differential t t ¯production cross section as a function of the jet mass and extraction of the top quark mass in hadronic decays of boosted top quarks
(Springer, 2023-07-03)
A measurement of the jet mass distribution in hadronic decays of Lorentz-boosted top quarks is presented. The measurement is performed in the lepton + jets channel of top quark pair production (t t ¯) events, where the ...
Search for Z′ bosons decaying to pairs of heavy Majorana neutrinos in proton-proton collisions at √s=13 TeV
(Springer, 2023-11-24)
A search for the production of pairs of heavy Majorana neutrinos (N-& ell;) from the decays of Z ' bosons is performed using the CMS detector at the LHC. The data were collected in proton-proton collisions at a center-of-mass ...
First measurement of the forward rapidity gap distribution in pPb collisions at √s NN = 8.16 TeV
(American Physical Society, 2023-11-20)
For the first time at LHC energies, the forward rapidity gap spectra from proton-lead collisions for both proton and lead dissociation processes are presented. The analysis is performed over 10.4 units of pseudorapidity ...
Observation of same-sign WW production from double parton scattering in proton-proton collisions at √s=13 TeV
(American Physical Society, 2023-09-01)
The first observation of the production of Formula Presented bosons from double parton scattering processes using same-sign electron-muon and dimuon events in proton-proton collisions is reported. The data sample corresponds ...
Addendum: Measurement and QCD analysis of double-differential inclusive jet cross sections in proton-proton collisions at √s=13 TeV
(Springer, 2022-12-07)
The QCD analysis at NNLO is repeated by using the NNLO interpolation grids for the double-differential inclusive jet cross section [1], which were released after the journal publication of the original analysis. The NNLOJET ...
Performance of the local reconstruction algorithms for the CMS hadron calorimeter with Run 2 data
(IOP Publishing, 2023-11)
A description is presented of the algorithms used to reconstruct energy deposited in the CMS hadron calorimeter during Run 2 (2015-2018) of the LHC. During Run 2, the characteristic bunch-crossing spacing for proton-proton ...
Measurements of the associated production of a W boson and a charm quark in proton–proton collisions at √s=8TeV
(Springer, 2022-12-05)
Measurements of the associated production of a W boson and a charm (c) quark in proton–proton collisions at a centre-of-mass energy of 8TeV are reported. The analysis uses a data sample corresponding to a total integrated ...
Top pair spin correlation studies in CMS
(Sissa Medialab Srl, 2021-02-08)
Measurement of tt¯ spin correlations are presented in event with top quarks produced in pp collisions at the LHC. The data correspond to an integrated luminosities of 19.5 fb-1 at vs = 8 TeV and 36 fb-1 at vs = 13 TeV ...
Search for bottom-type, vectorlike quark pair production in a fully hadronic final state in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2020-12-07)
A search is described for the production of a pair of bottom-type vectorlike quarks (VLQs), each decaying into a b or (b) over bar quark and either a Higgs or a Z boson, with a mass greater than 1000 GeV. The analysis is ...
