Search for the Standard Model Higgs Boson in theZH→νν¯bb¯Channel in5.2  fb−1ofpp¯Collisions ats=1.96  TeV

2010

A search is performed for the standard model Higgs boson in 5.2 fb-1 of p-pbar collisions at sqrt(s)=1.96 TeV, collected with the D0 detector at the Fermilab Tevatron Collider. The final state considered is a pair of b jets and large missing transverse energy, as expected from p-pbar->ZH->vvbb production. The search is also sensitive to the WH->lvbb channel when the charged lepton is not identified. For a Higgs boson mass of 115 GeV, a limit is set at the 95% C.L. on the cross section multiplied by branching fraction for p-pbar->(Z/W)H and H->bb that is a factor of 3.7 larger than the standard model value, consistent with the factor of 4.6 expected.

Search for Randall-Sundrum Gravitons in the Dielectron and Diphoton Final States with5.4  fb−1of Data frompp¯Collisions ats=1.96  TeV

2010

Using 5.4 fb-1 of integrated luminosity from ppbar collisions at sqrt(s)=1.96 TeV collected by the D0 detector at the Fermilab Tevatron Collider, we search for decays of the lightest Kaluza-Klein mode of the graviton in the Randall-Sundrum model to ee and gammagamma. We set 95% C.L. lower limits on the mass of the lightest graviton between 560 GeV and 1050 GeV for values of the coupling k/Mbar_pl between 0.01 and 0.1.

Search for the rare decayBs0→ϕμ+μ−with the D0 detector

2006

We present a search for the flavor-changing neutral current decay B-s(0)->phi mu(+)mu(-) using about 0.45 fb(-1) of data collected in p (p) over bar collisions at root s=1.96 TeV with the D0 detector at the Fermilab Tevatron Collider. We find an upper limit on the branching ratio of this decay normalized to B-s(0)-> J/psi phi of B(B-s(0)->phi mu(+)mu(-))/B(B-s(0)-> J/psi phi) J/psi phi, the limit corresponds to B(B-s(0)->phi mu(+)mu(-))< 4.1x10(-6) at the 95% C.L., the most stringent upper bound to date.

Search for large extra dimensions via single photon plus missing energy final states at s=1.96TeV

2008

Made available in DSpace on 2022-04-28T20:42:17Z (GMT). No. of bitstreams: 0 Previous issue date: 2008-06-30 We report on a search for large extra dimensions in a data sample of approximately 1fb-1 of pp̄ collisions at s=1.96TeV. We investigate Kaluza-Klein graviton production with a photon and missing transverse energy in the final state. At the 95% C.L. we set limits on the fundamental mass scale MD from 884to 778GeV for two to eight extra dimensions. © 2008 The American Physical Society.
