Search for R-parity violating supersymmetry via the LLE couplings lambda_{121}, lambda_{122} or lambda_{133} in ppbar collisions at sqrt(s)=1.96 TeV
A search for gaugino pair production with a trilepton signature in the
framework of R-parity violating supersymmetry via the couplings lambda_121,
lambda_122, or lambda_133 is presented. The data, corresponding to an
integrated luminosity of L~360/pb, were collected from April 2002 to August
2004 with the D0 detector at the Fermilab Tevatron Collider, at a
center-of-mass energy of sqrt(s)=1.96 TeV. This analysis considers final states
with three charged leptons with the flavor combinations eel, mumul, and eetau
(l=e or mu). No evidence for supersymmetry is found and limits at the 95%
confidence level are set on the gaugino pair production cross section and lower
bounds on the masses of the lightest neutralino and chargino are derived in two
supersymmetric models.Comment: 9 pages, 4 figures (fig2 includes 3 subfigures
Measurement of the Lifetime Using Semileptonic Decays
We report a measurement of the lifetime in the semileptonic decay
channel (and its charge conjugate), using
approximately 0.4 fb of data collected with the D0 detector during 2002
-- 2004. We have reconstructed 5176 signal events, where the
is identified via the decay , followed by . Using these events, we have measured the lifetime to be
. This is the most precise measurement of the lifetime to date.Comment: To appear in Phys. Rev. Lett., 7 pages, 2 figure
Search for Neutral Higgs Bosons Decaying to Tau Pairs in p-pbar Collisions at sqrt(s) = 1.96 TeV
A search for the production of neutral Higgs bosons Phi decaying into
tau^+tau^- final states in p-pbar collisions at a center-of-mass energy of 1.96
TeV is presented. The data, corresponding to an integrated luminosity of up to
348 pb^-1, were collected by the D0 experiment at the Fermilab Tevatron
Collider. Since no excess compared to the expectation from standard model
processes is found, limits on the production cross section times branching
ratio are set. The results are combined with those obtained from the D0 search
for Phi b(b) to b-bbar-b(bbar) and are interpreted in the minimal
supersymmetric standard model.Comment: Version accpeted by Phys. Rev. Lett. (minor changes
Search for the Rare Decay B0_s -> phi mu^+ mu- with the D0 Detector
We present a search for the flavor-changing neutral current decay B0_s -> phi
mu+ mu- using about 0.45 fb^-1 of data collected in p \bar p collisions at
sqrt{s} =1.96 TeV with the D{\O}detector at the Fermilab Tevatron Collider. We
find an upper limit on the branching ratio of this decay normalized to B0_s ->
J/psi phi of B(B0_s -> phi mu+ mu-)/B(B0_s -> J/psi phi) < 4.4\times 10^{-3} at
the 95% C.L. Using the central value of the world average branching fraction of
B0_s -> J/psi phi, the limit corresponds to B(B0_s -> phi mu+ mu-) < 4.1 \times
10^{-6} at the 95% C.L., the most stringent upper bound to date.Comment: 7 pages, 2 figures, LaTeX, to be submitted to Physical Review Letter
Multivariate searches for single top quark production with the D0 detector
We present a search for electroweak production of single top quarks in the
s-channel (p-pbar -> t bbar + X) and t-channel (p-pbar -> tq bbar + X) modes.
We have analyzed 230 pb^(-1) of data collected with the D0 detector at the
Fermilab Tevatron collider at a center-of-mass energy of sqrt(s) = 1.96 TeV.
Two separate analysis methods are used: neural networks and a cut-based
analysis. No evidence for a single top quark signal is found. We set 95%
confidence level upper limits on the production cross sections using Bayesian
statistics, based on event counts and binned likelihoods formed from the neural
network output. The limits from the neural network (cut-based) analysis are 6.4
pb (10.6 pb) in the s-channel and 5.0 pb (11.3 pb) in the t-channel.Comment: submitted to Phys. Rev. D, Fermilab preprint Fermilab-Pub-06/069-
Search for a heavy resonance decaying into a Z+jet final state in p-pbar collisions at sqrt(s) = 1.96 TeV using the D0 detector
We have searched for a heavy resonance decaying into a Z+jet final state in
p-pbar collisions at a center of mass energy of 1.96 TeV at the Fermilab
Tevatron collider using the D0 detector. No indication for such a resonance was
found in a data sample corresponding to an integrated luminosity of 370/pb. We
set upper limits on the cross section times branching fraction for heavy
resonance production at the 95% C.L. as a function of the resonance mass and
width. The limits are interpreted within the framework of a specific model of
excited quark production.Comment: 8 pages, 5 figures, submitted to Physical Review
Integrating human and ecosystem health through ecosystem services frameworks
The pace and scale of environmental change is undermining the conditions for human health. Yet the environment and human health remain poorly integrated within research, policy and practice. The ecosystem services (ES) approach provides a way of promoting integration via the frameworks used to represent relationships between environment and society in simple visual forms. To assess this potential, we undertook a scoping review of ES frameworks and assessed how each represented seven key dimensions, including ecosystem and human health. Of the 84 ES frameworks identified, the majority did not include human health (62%) or include feedback mechanisms between ecosystems and human health (75%). While ecosystem drivers of human health are included in some ES frameworks, more comprehensive frameworks are required to drive forward research and policy on environmental change and human health
