Prolonged use of atosiban and grade IV intraventricular haemorrhage in an infant born at 29 weeks and 4 days University of Antwerp
A woman in her second pregnancy (G2P1), with a prior history of preterm birth at 21 weeks, had been using vaginal progesterone suppositories as prophylaxis and presented with cervical shortening and funnelling. At 24 weeks, betamethasone and nifedipine was started because of contractions. At 26 weeks, a new period of preterm contractions emerged and atosiban was added. Attempts were made to stop administration of atosiban, but every time the ...
Search for new particles decaying to a jet and an emerging jet University of Antwerp Vrije Universiteit Brussel Ghent University
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 quark. The search is based on data corresponding to an integrated luminosity of 16.1 fb(-1) from proton-proton collisions at =13 TeV collected by the CMS experiment at the LHC in 2016. The dark quark is charged only under a ...
Search for new physics in top quark production in dilepton final states in proton-proton collisions at root s=13 TeV University of Antwerp Ghent University Vrije Universiteit Brussel
A search for new physics in top quark production is performed in proton-proton collisions at 13 TeV. The data set corresponds to an integrated luminosity of 35.9 fb(-1) collected in 2016 with the CMS detector. Events with two opposite-sign isolated leptons (electrons or muons), and b quark jets in the final state are selected. The search is sensitive to new physics in top quark pair production and in single top quark production in association ...
Extraction and validation of a new set of CMS pythia8 tunes from underlying-event measurements University of Antwerp Ghent University Vrije Universiteit Brussel
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-next-to-leading (NNLO) orders in perturbative quantum chromodynamics, and the strong coupling evolution at LO or NLO. Measurements of charged-particle multiplicity and transverse momentum densities at various hadron collision ...
A search for pair production of new light bosons decaying into muons in proton-proton collisions at 13 TeV University of Antwerp Ghent University
A search for new light bosons decaying into muon pairs is presented using a data sample corresponding to an integrated luminosity of 35.9 fb(-1) of proton-proton collisions at a center-of-mass energy root s = 13 TeV, collected with the CMS detector at the CERN LHC. The search is model independent, only requiring the pair production of a new light boson and its subsequent decay to a pair of muons. No significant deviation from the predicted ...
Search for new neutral Higgs bosons through the H -> ZA >l+l-bb process in pp collisions at s=13 TeV Ghent University University of Antwerp Vrije Universiteit Brussel
This paper reports on a search for an extension to the scalar sector of the standard model, where a new CP-even (odd) boson decays to a Z boson and a lighter CP-odd (even) boson, and the latter further decays to a b quark pair. The Z boson is reconstructed via its decays to electron or muon pairs. The analysed data were recorded in proton-proton collisions at a center-of-mass energy s = 13 TeV, collected by the CMS experiment at the LHC during ...
Search for high mass dijet resonances with a new background prediction method in proton-proton collisions at √s=13 TeV University of Antwerp Ghent University Vrije Universiteit Brussel
A search for narrow and broad resonances with masses greater than 1.8TeV decaying to a pair of jets is presented. The search uses proton-proton collision data at root s = 13TeV collected at the LHC, corresponding to an integrated luminosity of 137 fb(-1). The background arising from standard model processes is predicted with the fit method used in previous publications and with a new method. The dijet invariant mass spectrum is well described by ...
Search for new physics in final states with a single photon and missing transverse momentum in proton-proton collisions at $\sqrt{s}$=13 TeV University of Antwerp Ghent University Vrije Universiteit Brussel
A search is conducted for new physics in final states containing a photon and missing transverse momentum in proton-proton collisions at s=13 TeV, using the data collected in 2016 by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 fb(-1). No deviations from the predictions of the standard model are observed. The results are interpreted in the context of dark matter production and models containing extra spatial ...
Search for a new scalar resonance decaying to a pair of Z bosons in proton-proton collisions at root s=13 TeV Ghent University University of Antwerp Vrije Universiteit Brussel
A search for a new scalar resonance decaying to a pair of Z bosons is performed in the mass range from 130 GeV to 3TeV, and for various width scenarios. The analysis is based on proton-proton collisions recorded by the CMS experiment at the LHC in 2016, corresponding to an integrated luminosity of 35.9 fb(-1) at a center-of-mass energy of 13TeV. The Z boson pair decays are reconstructed using the 4l, 2l2q, and 2l2 nu final states, where l = e or ...
