Study of the decay Bs0→J/ψf2′(1525) in μ+μ−K+K− final states

V. M. Abazov, B. Abbott, B. S. Acharya, M. Adams et autres

We investigate the decay ${B}_{s}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{+}{K}^{\ensuremath{-}}$ for invariant masses of the ${K}^{+}{K}^{\ensuremath{-}}$ pair in the range $1.35<M({K}^{+}{K}^{\ensuremath{-}})<2\text{ }\text{ }\mathrm{GeV}$. The data sample corresponds to an integrated luminosity of $10.4\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ accumulated with the D0 detector …

Measurement of angular correlations of jets at s=1.96 TeV and determination of the strong coupling at high momentum transfers

V. M. Abazov, B. Abbott, B. S. Acharya, M. Adams et autres

We present a measurement of the average value of a new observable at hadron colliders that is sensitive to QCD dynamics and to the strong coupling constant, while being only weakly sensitive to parton distribution functions. The observable measures the angular correlations …

Search for large extra dimensions in dimuon and dielectron events in pp collisions at s=7 TeV

S. Chatrchyan, V. Khachatryan, A. M. Sirunyan, A. Tumasyan et autres

Results are presented from a search for large, extra spatial dimensions in events with either two isolated muons or two isolated electrons. The data are from proton–proton interactions at s = 7 TeV collected with the CMS detector at the LHC. The …

Precise Measurement of the Top Quark Mass in the Dilepton Channel at D0

V. M. Abazov, B. Abbott, B. S. Acharya, M. Adams et autres

We measure the top quark mass (${m}_{t}$) in $p\overline{p}$ collisions at a center of mass energy $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ using dilepton $t\overline{t}\ensuremath{\rightarrow}{W}^{+}b{W}^{\ensuremath{-}}\overline{b}\ensuremath{\rightarrow}{\ensuremath{\ell}}^{+}{\ensuremath{\nu}}_{\ensuremath{\ell}}b{\ensuremath{\ell}}^{\ensuremath{-}}{\overline{\ensuremath{\nu}}}_{\ensuremath{\ell}}\overline{b}$ events, where $\ensuremath{\ell}$ denotes an electron, a muon, or a tau that decays leptonically. The data correspond to an integrated …

Combination of tt¯ cross section measurements and constraints on the mass of the top quark and its decays into charged Higgs bosons
