Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H → γγ, H→ZZ∗→4l and H→WW∗→ lνlν. The results are based on… (More)
In this Letter we report on a search for long-lived particles that decay into final states with two electrons or photons. Such long-lived particles arise in a variety of theoretical models, such as… (More)
We report observation of the electroweak production of single top quarks in pp[over ] collisions at sqrt[s]=1.96 TeV based on 2.3 fb(-1) of data collected by the D0 detector at the Fermilab Tevatron… (More)

The production of Z bosons with one or two isolated high-energy photons is studied using pp collisions at ffiffi ffi s p ¼ 8 TeV. The analyses use a data sample with an integrated luminosity of 20.3… (More)

We present a measurement of the ratio of top quark branching fractions R=B(t→Wb)/B(t→Wq), where q can be a d, s, or b quark, in the lepton+jets and dilepton tt final states. The measurement uses data… (More)
