Structural Forecasts for the Danish Economy Using the Dynamic-AAGE Model
We describe how an applied dynamic general equilibrium model of the Danish economy has been developed to generate structural forecasts. The forecasts provide a microeconomic picture that is consistent with a macroeconomic scenario and the other inputs. We provide an overview of the inputs required to generate the forecasts and of the forecast methodology. Finally, we present aspects of the forecasting results.Research and Development/Tech Change/Emerging Technologies,
A case of mistaken identity ā reappraisal of the species of canid and felid hookworms (Ancylostoma) present in Australia and India
This study serves to clarify the current status of canid and felid Ancylostoma species present in Australia. The morphological identification of A. ceylanicum from cats for the first time in Townsville, Australia, appears to be in error, together with the genetic markers provided for the species. Morphological and genetic data presented herein provide strong evidence that the hookworms from cats in Towsville are not A. ceylanicum as previously identified (i.e. the first report of this species in Australia), but are A. braziliense. Therefore the subsequent genetic markers established for A. ceylanicum in subsequent molecular studies based on these Townsville specimens should also be attributed to A. braziliense. Based on this information, a study of canine hookworm species present in northern India is also in error and it is apparent that the hookworms found in this region are those of A. ceylanicum. The distribution of A. braziliense and A. ceylanicum in the Americas and Asia Pacific region is discussed together with the importance of combining parasite morphology with genetic data for parasite diagnosis in epidemiological studies
Studies of WW and WZ production and limits on anomalous WWĪ³ and WWZ couplings
This is the publisher's version, also available electronically from http://journals.aps.org/prd/abstract/10.1103/PhysRevD.60.072002.Evidence of anomalous WW and WZ production was sought in pp-bar collisions at a center-of-mass energy of sā=1.8TeV. The final states WW(WZ)āĪ¼Ī½ jet jet+X, WZā Ī¼Ī½ee+X and WZā eĪ½ee+X were studied using a data sample corresponding to an integrated luminosity of approximately 90pb-1. No evidence of anomalous diboson production was found. Limits were set on anomalous WWĪ³ and WWZ couplings and were combined with our previous results. The combined 95% confidence level anomalous coupling limits for Ī=2TeV are -0.25<~ĪĪŗ<~0.39 (Ī»=0) and -0.18<~Ī»<~0.19 (ĪĪŗ=0), assuming the WWĪ³ couplings are equal to the WWZ couplings

Measurement of the angular distribution of electrons from Wā eĪ½ decays observed in pp-bar collisions at sā=1.8 TeV
This is the publisher's version, also available electronically from http://journals.aps.org/prd/abstract/10.1103/PhysRevD.63.072001.We present the first measurement of the electron angular distribution parameter Ī±(2) in Wā eĪ½ events produced in proton-antiproton collisions as a function of the W boson transverse momentum. Our analysis is based on data collected using the DĆ detector during the 1994ā1995 Fermilab Tevatron run. We compare our results with next-to-leading order perturbative QCD, which predicts an angular distribution of (1Ā±Ī±(1c)osĪø*+Ī±(2)cos(2)Īø*), where Īø* is the polar angle of the electron in the Collins-Soper frame. In the presence of QCD corrections, the parameters Ī±(1) and Ī±(2) become functions of pWT, the W boson transverse momentum. This measurement provides a test of next-to-leading order QCD corrections which are a non-negligible contribution to the W boson mass measurement

Measurement of the B0s Lifetime in the Flavor-Specific Decay Channel B0sāDāsĪ¼+Ī½X
This is the published version. Copyright 2015 American Physical SocietyWe present an updated measurement of the B0s lifetime using the semileptonic decays B0sāDāsĪ¼+Ī½X, with DāsāĻĻā and ĻāK+Kā (and the charge conjugate process). This measurement uses the full Tevatron Run II sample of proton-antiproton collisions at sā=1.96āāTeV, comprising an integrated luminosity of 10.4āāfbā1. We find a flavor-specific lifetime Ļfs(B0s)=1.479Ā±0.010(stat)Ā±0.021(syst)āāps. This technique is also used to determine the B0 lifetime using the analogous B0āDāĪ¼+Ī½X decay with DāāĻĻā and ĻāK+Kā, yielding Ļ(B0)=1.534Ā±0.019(stat)Ā±0.021(syst)āāps. Both measurements are consistent with the current world averages, and the B0s lifetime measurement is one of the most precise to date. Taking advantage of the cancellation of systematic uncertainties, we determine the lifetime ratio Ļfs(B0s)/Ļ(B0)=0.964Ā±0.013(stat)Ā±0.007(syst)
Constraints on Models for the Higgs Boson with Exotic Spin and Parity in VH ā VbĀÆb Final States
This is the published version. Copyright Ā© 2014 American Physical SocietyWe present constraints on models containing non-standard-model values for the spin J and parity P of the Higgs boson H in up to 9.7āāfbā1 of ppĀÆ collisions at sā=1.96āāTeV collected with the D0 detector at the Fermilab Tevatron Collider. These are the first studies of Higgs boson JP with fermions in the final state. In the ZHāāābbĀÆ, WHāāĪ½bbĀÆ, and ZHāĪ½Ī½bbĀÆ final states, we compare the standard model (SM) Higgs boson prediction, JP=0+, with two alternative hypotheses, JP=0ā and JP=2+. We use a likelihood ratio to quantify the degree to which our data are incompatible with non-SM JP predictions for a range of possible production rates. Assuming that the production rate in the signal models considered is equal to the SM prediction, we reject the JP=0ā and JP=2+ hypotheses at the 97.6% CL and at the 99.0% CL, respectively. The expected exclusion sensitivity for a JP=0ā (JP=2+) state is at the 99.86% (99.94%) CL. Under the hypothesis that our data are the result of a combination of the SM-like Higgs boson and either a JP=0ā or a JP=2+ signal, we exclude a JP=0ā fraction above 0.80 and a JP=2+ fraction above 0.67 at the 95% CL. The expected exclusion covers JP=0ā (JP=2+) fractions above 0.54 (0.47)
Search for dilepton signatures from minimal low-energy supergravity in pp-bar collisions at sā=1.8 TeV
This is the publisher's version, also available electronically from http://journals.aps.org/prd/abstract/10.1103/PhysRevD.63.091102.We report on a search for supersymmetry using the DĆ detector. The 1994ā1996 data sample of sā=1.8 TeV pp-bar collisions was analyzed for events containing two leptons (e or Ī¼), two or more jets, and missing transverse energy. Assuming the minimal supergravity model, with A(0)=0 and Ī¼<0, various thresholds were employed to optimize the search. No events were found beyond expectation from the background. We set a lower limit at the 95% C.L. of 255 GeV/c(2) for equal mass squarks and gluinos for tanĪ²=2, and present exclusion contours in the (m(0),m(1/2)) plane for tanĪ²=2ā6
