Search for new phenomena with multiple charged leptons in proton–proton collisions at s√=13 TeV
(Springer International Publishing, 2017-09-22)
Results are reported from a search for physics beyond the standard model in final states with at least three charged leptons, in any combination of electrons or muons. The data sample corresponds to an integrated luminosity ...
Measurement of neutral strange particle production in the underlying event in proton-proton collisions at root s=7 TeV
(American Physical Society, 2013-09-01)
Measurements are presented of the production of primary K-S(0) and Lambda particles in proton-proton collisions at root s = 7 TeV in the region transverse to the leading charged-particle jet in each event. The average ...
Search for associated production of a Z boson with a single top quark and for tZ flavour-changing interactions in pp collisions at s√=8 TeV
(Springer International Publishing, 2017-07-03)
A search for the production of a single top quark in association with a Z boson is presented, both to identify the expected standard model process and to search for flavour-changing neutral current interactions. The data ...
Search for dark matter and unparticles in events with a Z boson and missing transverse momentum in proton-proton collisions at s√=13 TeV
(Springer International Publishing, 2017-03-10)
A search for dark matter and unparticle production at the LHC has been performed using events containing two charged leptons (electrons or muons), consistent with the decay of a Z boson, and large missing transverse momentum. ...
Searches for physics beyond the standard model with the MT2 variable in hadronic final states with and without disappearing tracks in proton–proton collisions at √s = 13 TeV
(Springer Nature, 2020-01-03)
Two related searches for phenomena beyond the standard model (BSM) are performed using events with hadronic jets and significant transverse momentum imbalance. The results are based on a sample of proton-proton collisions ...
Extraction and validation of a new set of CMS PYTHIA8 tunes from underlying-event measurements
(Springer Nature, 2020-01-03)
New sets of CMS underlying-event parameters ("tunes") are presented for the pythia8 event generator. These tunes use the NNPDF3.1 parton distribution functions (PDFs) at leading (LO), next-to-leading (NLO), or next-to-ne ...
Measurement of the top quark Yukawa coupling from t¯t kinematic distributions in the lepton + jets final state in proton-proton collisions at √ s = 13 TeV
(American Physical Society, 2019-10-17)
Results are presented for an extraction of the top quark Yukawa coupling from top quark-antiquark (t (t) over bar) kinematic distributions in the lepton plus jets final state in proton-proton collisions, based on data ...
Search for associated production of dark matter with a Higgs boson decaying to bb¯ or γγ at √s = 13 TeV
(Springer International Publishing, 2017-10-26)
A search for dark matter is performed looking for events with large missing transverse momentum and a Higgs boson decaying either to a pair of bottom quarks or to a pair of photons. The data from proton-proton collisions ...
Search for a standard model Higgs boson produced in association with a top-quark pair and decaying to bottom quarks using a matrix element method
(Springer Nature, 2015-06)
A search for a standard model Higgs boson produced in association with a top-quark pair and decaying to bottom quarks is presented. Events with hadronic jets and one or two oppositely charged leptons are selected from a ...
Search for charged Higgs bosons in the H± → τ±ντ decay channel in proton-proton collisions at s√=13 TeV
(Springer Nature, 2019-07-24)
A search is presented for charged Higgs bosons in the H± → τ ± ντ decay mode in the hadronic final state and in final states with an electron or a muon. The search is based on proton-proton collision data recorded by the ...
