Observation of a new Xi(b) baryon
(American Physical Society, 2012-06-22)
The observation of a new b baryon via its strong decay into Xi(-)(b)pi(+) (plus charge conjugates) is reported. The measurement uses a data sample of pp collisions at root s = 7 TeV collected by the CMS experiment at the ...
Measurements of the pp → WZ inclusive and differential production cross sections and constraints on charged anomalous triple gauge couplings at s√ = 13 TeV
(Springer Nature, 2019-04-18)
The WZ production cross section is measured in proton-proton collisions at a centre-of-mass energy = 13 TeV using data collected with the CMS detector, corresponding to an integrated luminosity of 35.9 fb(-1). The inclusive ...
Identification of heavy, energetic, hadronically decaying particles using machine-learning techniques
(IOP Publishing, 2020-06)
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. ...
Search for long-lived particles decaying into displaced jets in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2019-02-21)
A search for long-lived particles decaying into jets is presented. Data were collected with the CMS detector at the LHC from proton-proton collisions at a center-of-mass energy of 13 TeV in 2016, corresponding to an ...
Search for new physics in final states with a single photon and missing transverse momentum in proton-proton collisions at s√=13 TeV
(Springer Nature, 2019-02-13)
A search is conducted for new physics in final states containing a photon and missing transverse momentum in proton-proton collisions at <mml:msqrt>s</mml:msqrt>=13 TeV, using the data collected in 2016 by the CMS experiment ...
Search for pair-produced resonances decaying to quark pairs in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2018-12)
A general search for the pair production of resonances, each decaying to two quarks, is reported. The search is conducted separately for heavier resonances (masses above 400 GeV), where each of the four final-state quarks ...
Search for a charged Higgs boson decaying to charm and bottom quarks in proton-proton collisions at s√=8 TeV
(Springer Nature, 2018-11)
A search for charged Higgs boson decaying to a charm and a bottom quark (H +→ c b ¯) is performed using 19.7 fb−1 of pp collision data at s=8 TeV. The production mechanism investigated in this search is t t ¯ pair production ...
Angular analysis of the decay B + → K + μ + μ − in proton-proton collisions at √s =8 TeV
(American Physical Society, 2018-12-01)
The angular distribution of the flavor-changing neutral current decay B+→K+μ+μ- is studied in proton-proton collisions at a center-of-mass energy of 8 TeV. The analysis is based on data collected with the CMS detector at ...
Search for the decay of a Higgs boson in the ℓℓγ channel in proton-proton collisions at s√=13 TeV
(Springer Nature, 2018-11)
A search for a Higgs boson decaying into a pair of electrons or muons and a photon is described. Higgs boson decays to a Z boson and a photon (H → Zγ → ℓℓγ, ℓ = e or μ), or to two photons, one of which has an internal ...
Event shape variables measured using multijet final states in proton-proton collisions at s√=13 TeV
(Springer Nature, 2018-12-01)
The study of global event shape variables can provide sensitive tests of predictions for multijet production in proton-proton collisions. This paper presents a study of several event shape variables calculated using jet ...
