Search for supersymmetry in events with one lepton and multiple jets in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2017-01)
A search for supersymmetry is performed in events with a single electron or muon in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were recorded by the CMS experiment at the LHC and correspond to ...
Study of the underlying event at forward rapidity in pp collisions at √s=0.9,2.76, and 7 TeV
(Springer Science and Business Media LLC, 2013)
© 2013, CERN. The underlying event activity in proton-proton collisions at forward pseudo-rapidity (—6.6 < η < —5.2) is studied with the CMS detector at the LHC, using a novel observable: the ratio of the forward energy ...
Search for flavor changing neutral currents in top quark decays in pp collisions at 7 TeV
(Elsevier BV, 2013)
The results of a search for flavor changing neutral currents in top quark decays t→Zq in events with a topology compatible with the decay chain tt̄→Wb+Zq→ℓνb+ℓℓq are presented. The search is performed with a data sample ...
Search for top squark pair production in compressed-mass-spectrum scenarios in proton–proton collisions at √s = 8 TeV using the αT variable
(Elsevier BV, 2017)
© 2017 The Author An inclusive search is performed for supersymmetry in final states containing jets and an apparent imbalance in transverse momentum, p→Tmiss, due to the production of unobserved weakly interacting particles ...
Performance of τ-lepton reconstruction and identification in CMS
(IOP Publishing, 2012-01-01)
The performance of τ-lepton reconstruction and identification algorithms is studied using a data sample of proton-proton collisions at s = 7 TeV, corresponding to an integrated luminosity of 36 pb-1 collected with the CMS ...
Search for supersymmetry in proton-proton collisions at 13 TeV using identified top quarks
(American Physical Society, 2018-01)
A search for supersymmetry is presented based on proton-proton collision events containing identified hadronically decaying top quarks, no leptons, and an imbalance p [superscript miss] [subscript T] in transverse momentum. ...
Search for the Higgs Boson Decaying to Two Muons in Proton-Proton Collisions at √s = 13 TeV
(American Physical Society, 2019-01)
A search for the Higgs boson decaying to two oppositely charged muons is presented using data recorded by the CMS experiment at the CERN LHC in 2016 at a center-of-mass energy √s = 13 TeV, corresponding to an integrated ...
Comparing transverse momentum balance of b jet pairs in pp and PbPb collisions at sNN=5.02$$ \sqrt{s_{\mathrm{NN}}}=5.02 $$ TeV
(Springer, 2018-03)
The transverse momentum balance of pairs of back-to-back b quark jets in PbPb and pp collisions recorded with the CMS detector at the LHC is reported. The center-of-mass energy in both collision systems is 5.02 TeV per ...
First simultaneous measurement of the top quark mass in the lepton + jets and dilepton channels at CDF
(American Physical Society (APS), 2009-05)
We present a measurement of the mass of the top quark using data corresponding to an integrated luminosity of 1.9fb[superscript -1] of pp̄ collisions collected at √s = 1.96TeV with the CDF II detector at Fermilab's Tevatron. ...
First Search for Exotic Z Boson Decays into Photons and Neutral Pions in Hadron Collisions
(American Physical Society, 2014-03)
A search for forbidden and exotic Z boson decays in the diphoton mass spectrum is presented for the first time in hadron collisions, based on data corresponding to 10.0 fb[superscript −1] of integrated luminosity from ...
