Measurement of correlated μ-b¯ jet cross sections in pp¯ collisions at s=1.8 TeV

Le résumé fourni par la source

We report on measurements of differential \ensuremath{\mu}-b\ifmmode\bar\else\textasciimacron\fi{} cross sections, where the muon is from a semileptonic b decay and the b\ifmmode\bar\else\textasciimacron\fi{} is identified using precision track reconstruction in jets. The semidifferential correlated cross sections d\ensuremath{\sigma}/${\mathit{dE}}_{\mathit{T}}^{\mathit{b}\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}$, d\ensuremath{\sigma}/${\mathit{dp}}_{\mathit{T}}^{\mathit{b}\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}$, and d\ensuremath{\sigma}/d\ensuremath{\delta}\ensuremath{\varphi}(\ensuremath{\mu}-b\ifmmode\bar\else\textasciimacron\fi{}) for ${\mathit{p}}_{\mathit{T}}^{\mathrm{\ensuremath{\mu}}}$\ensuremath{\gtrsim}9 GeV/c, \ensuremath{\Vert}${\mathrm{\ensuremath{\eta}}}^{\mathrm{\ensuremath{\mu}}}$\ensuremath{\Vert}〈0.6,${\mathit{E}}_{\mathit{T}}^{\mathit{b}\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}$〉 10 GeV, \ensuremath{\Vert}${\mathrm{\ensuremath{\eta}}}^{\mathit{b}\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}$\ensuremath{\Vert}1.5 are presented and compared to next-to-leading order QCD calculations. \textcopyright{} 1996 The American Physical Society.
