  • Vbfnlo: A parton level Monte Carlo for processes with electroweak bosons
    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 ...

  • Evidence for $\text {W}\text {W}$ production from double-parton interactions in proton–proton collisions at $\sqrt{s} = 13 \,\text {TeV} $
    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.

  • Measurement of single-diffractive dijet production in proton-proton collisions at $\sqrt{s} =$ 8 TeV with the CMS and TOTEM experiments
    Measurements are presented of the single-diffractive dijet cross section and the diffractive cross section as a function of the proton fractional momentum loss $\xi$ and the four-momentum transfer squared $t$. Both processes $\mathrm{pp} \to \mathrm{pX}$ and $\mathrm{pp} \to \mathrm{Xp}$, i.e. with the proton scattering to either side of the interaction point, are measured, where $\mathrm{X}$ includes at least two jets; the results of the two processes are averaged. The analyses are based on data collected simultaneously with the CMS and TOTEM detectors at the LHC in proton-proton collisions at $\sqrt{s} = 8\,\mathrm{TeV}$ during a dedicated run with $\beta^{\ast} = 90\,\mathrm{m}$ at low instantaneous luminosity and correspond to an integrated luminosity of $37.5\,\mathrm{nb}^{-1}$. The single-diffractive dijet cross section $\sigma^{\mathrm{pX}}_{\mathrm{jj}}$, in the kinematic region $\xi < 0.1$, $0.03 < \lvert t \rvert < 1\,\mathrm{GeV}^2$, with at least two jets with transverse momentum $p_{\mathrm{T}} > 40\,\mathrm{GeV}$, and pseudorapidity $\lvert \eta \rvert < 4.4$, is $21.7 \pm 0.9\,\text{(stat)} \,^{+3.0}_{-3.3}\,\text{(syst)} \pm 0.9\,\text{(lumi)} \,\mathrm{nb}$. The ratio of the single-diffractive to inclusive dijet yields, normalised per unit of $\xi$, is presented as a function of $x$, the longitudinal momentum fraction of the proton carried by the struck parton. The ratio in the kinematic region defined above, for $x$ values in the range $-2.9 \leq \log_{10} x \leq -1.6$, is $R = (\sigma^{\mathrm{pX}}_{\mathrm{jj}}/\Delta\xi)/\sigma_{\mathrm{jj}} = 0.025 \pm 0.001\,\text{(stat)} \pm 0.003\,\text{(syst)}$, where $\sigma^{\mathrm{pX}}_{\mathrm{jj}}$ and $\sigma_{\mathrm{jj}}$ are the single-diffractive and inclusive dijet cross sections, respectively. The results are compared with predictions from models of diffractive and nondiffractive interactions. Monte Carlo predictions based on the HERA diffractive parton distribution functions agree well with the data when corrected for the effect of soft rescattering between the spectator partons.

  • Measurement of prompt $\psi$(2S) production cross sections in proton-lead and proton-proton collisions at $\sqrt{s_{_\mathrm{NN}}}=$ 5.02 TeV
    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 $
