Measurement of Bc(2S)+ and Bc*(2S)+ cross section ratios in proton-proton collisions at s=13 TeV
(American Physical Society, 2020-11-16)
The ratios of the B-c (2S)(+) to B-c(+), B-c(*)(2S)(+) to B-c(+), and Bc(2S)(+) to Bco2STHORNthorn production cross sections are measured in proton-proton collisions at root s = 13 TeV, using a data sample collected by the ...
Measurement of the cross section for electroweak production of a Z boson, a photon and two jets in proton-proton collisions at √s = 13 TeV and constraints on anomalous quartic couplings
(Springer Nature, 2020-06-10)
A measurement is presented of the cross section for electroweak production of a Z boson and a photon in association with two jets (Z gamma jj) in proton-proton collisions. The Z boson candidates are selected through their ...
Investigation into the event-activity dependence of ϒ(nS) relative production in proton-proton collisions at s√ = 7 TeV
(Springer Nature, 2020-11-02)
The ratios of the production cross sections between the excited gamma(2S) and gamma(3S) mesons and the gamma(1S) ground state, detected via their decay into two muons, are studied as a function of the number of charged ...
Observation of t ¯ t H production
(American Physical Society, 2018-06-04)
The observation of Higgs boson production in association with a top quark-antiquark pair is reported, based on a combined analysis of proton-proton collision data at center-of-mass energies of root s = 7, 8, and 13 TeV, ...
Search for long-lived particles using delayed photons in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2019-12-09)
A search for long-lived particles decaying to photons and weakly interacting particles, using protonproton collision data at root s = 13 TeV collected by the CMS experiment in 2016-2017 is presented. The data set corresponds ...
Search for new particles decaying to a jet and an emerging jet
(Springer Nature, 2019-02-26)
A search is performed for events consistent with the pair production of a new heavy particle that acts as a mediator between a dark sector and normal matter, and that decays to a light quark and a new fermion called a dark ...
Measurements of tt¯ differential cross sections in proton-proton collisions at s√=13 TeV using events containing two leptons
(Springer Nature, 2019-02-22)
Measurements of differential top quark pair t (t) over bar cross sections using events produced in proton-proton collisions at a centre-of-mass energy of 13 TeV containing two oppositely charged leptons are presented. The ...
Measurement of the tt¯ production cross section, the top quark mass, and the strong coupling constant using dilepton events in pp collisions at s√ = 13TeV
(Springer Nature, 2019-04-29)
A measurement of the top quark-antiquark pair production cross section sigma(t (t) over bar) in proton-proton collisions at a centre-of-mass energy of 13 TeV is presented. The data correspond to an integrated luminosity ...
Measurements of t¯tH production and the CP structure of the Yukawa interaction between the Higgs Boson and top quark in the diphoton decay channel
(American Physical Society, 2020-08-05)
The first observation of the (tt) over barH process in a single Higgs boson decay channel with the full reconstruction of the final state (H -> gamma gamma) is presented, with a significance of 6.6 standard deviations ...
Search for top squarks decaying via four-body or chargino-mediated modes in single-lepton final states in proton-proton collisions at √s=13 TeV
(Springer Nature, 2018-09)
A search for the pair production of the lightest supersymmetric partner of the top quark ((t) over tilde (1)) is presented. The search focuses on a compressed scenario where the mass difference between the top squark and ...
