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 ...
Some remarks on the stability and instability properties of solitary waves for the double dispersion equation
(Estonian Academy of Sciences, 2015)
In this article we give a review of our recent results on the instability and stability properties of travelling wave solutions of the double dispersion equation utt − uxx + auxxxx − buxxtt = −(|u|p−1u)xx for p > 1, a ≥ b ...
Unidirectional wave motion in a nonlocally and nonlinearly elastic medium: The KdV, BBM and CH equations
(Estonian Academy of Sciences, 2015)
We consider unidirectional wave propagation in a nonlocally and nonlinearly elastic medium whose constitutive equation is given by a convolution integral with a suitable kernel function. We first give a brief review of ...
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 ...
Search for a light pseudoscalar Higgs boson in the boosted μμττ final state in proton-proton collisions at s√ = 13 TeV
(Springer Nature, 2020-08-27)
A search for a light pseudoscalar Higgs boson (a) decaying from the 125 GeV (or a heavier) scalar Higgs boson (H) is performed using the 2016 LHC proton-proton collision data at root s = 13 TeV, corresponding to an integrated ...
Studies of beauty suppression via nonprompt D 0 mesons in Pb-Pb collisions at √s NN = 5.02 TeV
(American Physical Society, 2019-07-09)
The transverse momentum spectra of D-0 mesons from b hadron decays are measured at midrapidity (vertical bar y vertical bar < 1) in pp and Pb-Pb collisions at a nucleon-nucleon center of mass energy of 5.02 TeV with the ...
Measurement of properties of B 0 s → µ + µ − decays and search for B 0 → µ + µ − with the CMS experiment
(Springer Nature, 2020-04-28)
Results are reported for the B 0s ! + branching fraction and effective lifetime and from a search for the decay B0 ! + . The analysis uses a data sample of proton-proton collisions accumulated by the CMS experiment in 2011, ...
