  • This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract Vbfnlo is a fully flexible parton level Monte Carlo program for the simulation of vector boson fusion, double and triple vector boson production in hadronic collisions at next-to-leading order in the strong coupling constant. Vbfnlo includes Higgs and vector boson decays with full spin correlations and all off-shell effects. In addition, Vbfnlo implements CP-even and CP-odd Higgs boson via gluon fusion, associated with two jets, at the leading-order one-loop level with the full top- a... Title of program: VBFNLO Catalogue Id: AEDO_v1_0 Nature of problem To resolve the large scale dependence inherent in leading order calculations and to quantify the cross section error induced by uncertainties in the determination of parton distribution functions, it is necessary to include NLO corrections. Moreover, whenever stringent cuts are required on decay products and/or identified jets the question arises whether the scale dependence and a k-factor, defined as the ratio of NLO to LO cross section, determined for the inclusive production cross sections ar ...

  • A search for WW production from double-parton scattering processes using same-charge electron-muon and dimuon events is reported, based on proton-proton collision data collected at a center-of-mass energy of 13 TeV. The analyzed data set corresponds to an integrated luminosity of 77.4 invfb, collected using the CMS detector at the LHC in 2016 and 2017. Multivariate classifiers are used to discriminate between the signal and the dominant background processes. A maximum likelihood fit is performed to extract the signal cross section. This leads to the first evidence for double-parton scattering WW production, with a significance of 3.9 standard deviations. The measured inclusive cross section is 1.41 +/- 0.28 (stat.) +/- 0.28 (syst.) pb.

  • CERN-LHC. Measurements of prompt $\psi$(2S) meson production in proton-proton (pp) and proton-lead (pPb) collisions at a center-of-mass energy per nucleon pair of 5.02 TeV are reported. The results are based on pPb and pp data collected by the CMS experiment at the LHC, corresponding to integrated luminosities of 34.6 nb$^{−1}$ and 28.0 pb$^{−1}$, respectively. The nuclear modification factor, $R_{\mathrm{pPb}}$ is measured for prompt $\psi$(2S) in the transverse momentum range 4 $

  • CERN-LHC. Measurement of electroweak WZ boson production and search for new physics in WZ + two jets events in pp collisions at sqrt(s)= 13 TeV. The final states used are 3 charged electrons or muons, MET and 2 jets. Selection for WZ, EWK WZ (loose and tight regions) and aQGC regions: - 3e, 2e 1mu, 2mu 1e, or 3mu - kinematic selection - Ambiguities in pairing are resolved by choosing the combination that results in the smallest value of the sum |mll - mZ| for one of the two pairs, where mll is the mass of the dilepton system and mZ = 91.2 GeV. - ptLepton > 25 (15) GeV for the two leptons consistent with being from a Z boson - ptLepton > 20 for the lepton consistent with being from a W boson - |etaLepton| < 2.5 (2.4) for electrons (muons) - Z: At least one opposite charge same flavor lepton pair is required to have invariant mass within 15 GeV of mZ = 91.2 GeV - Z: Three charged lepton mass m3l > 100 GeV - W: pTmiss > 30 GeV - All chareged lepton pairs required to have mll > 4 GeV - pTjet > 30 GeV, 2 jets required - |etaJ| < 4.7 - mjj > 500 GeV - |deltaetajj| > 2.5 - min(DeltaR(l,j)) > 0.4 - min(DeltaR(l,l)) > 0.02 and electrons from muons by min(DeltaR(l,l)) > 0.05. - non Kinematic selection: non applied as part of loose and tight fiducial region selections - The tranverse distance of clossest approach between each lepton candidate and the event vertex is required ot be less than 0.05 cm electrons barrel, 0.10 electrons endcap, 0.02 muons - The logitudinal distace of clossest approach between each lepton candidate and the event vertex is required ot be less than 0.1 cm electrons barrel, 0.2 electrons endcap, 0.1 muons - Riso defined as the sum of charged hadron, neutral hadron, photon pT minus pile up contributions over pTLepton in a cone of deltaR < 0.3 (electrons) < 0.4 (muons) is requred to be less than 0.036 electrons barrel, 0.096 electrons endcap and 0.15 muons - events with b jets are vetored - events with additional letpons with pt > 10 GeV are votoed The Fiducial loose selection (note many selections above are considered part of the efficiency for the loose and tight fidicial region selections: - See Table 1 - ptl > 20(20) for letpons from the Z boson: looser/tighter than selection above - |etamuon| < 2.5: looser than selection above and equal to electron value - no pTmiss selection: looser than selection above - other kinematic selection as above - non kinematic selection not applied as part of fidicial region definition The Fiducial tight selection (note many selections above are considered part of the efficiency for the loose and tight fidicial region selections: - See Table 1 - ptl > 25(15) for letpons from the Z boson: tighter/losser than selection above - |etamuon| < 2.5: looser than selection above and equal to electron value - no pTmiss selection: looser than selection above - ptjet> 50: tighter than selection above - Zepenfield variable, |eta3l-(etaj1+etaj2)/2| < 2.5 - other kinematic selection as above - non kinematic selection not applied as part of fidicial region definition EWK and aTGC search region: Not used to define fiducial regions, additinal selection result in an extrapolation to the fiducial region.
