Studying the underlying event in Drell-Yan and high transverse momentum jet production at the Tevatron

T. Aaltonen, J. Adelman, B. Álvarez González, S. Amerio et autres

We study the underlying event in proton-antiproton collisions by examining the behavior of charged particles produced in association with a large transverse momentum jet ($\ensuremath{\sim}2.2\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$) or with a Drell-Yan lepton pair ($\ensuremath{\sim}2.7\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$) in the $Z$-boson mass region [$70<M(\mathrm{\text{pair}})<110\text{ …

Combined Tevatron upper limit on gg→H→W+W− and constraints on the Higgs boson mass in fourth-generation fermion models

T. Aaltonen, V. M. Abazov, B. Abbott, M. Abolins et autres

We combine results from searches by the CDF and D0 collaborations for a standard model Higgs boson ($H$) in the process $gg\ensuremath{\rightarrow}H\ensuremath{\rightarrow}{W}^{+}{W}^{\ensuremath{-}}$ in $p\overline{p}$ collisions at the Fermilab Tevatron Collider at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$. With $4.8\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of integrated luminosity analyzed …

T. Aaltonen, J. Adelman, B. Álvarez González, S. Amerio et autres

We present a measurement of the top quark mass and of the top-antitop ($t\overline{t}$) pair production cross section using $p\overline{p}$ data collected with the CDF II detector at the Tevatron Collider at the Fermi National Accelerator Laboratory and corresponding to an integrated …

Search for a Standard Model Higgs Boson in WH→ℓvbb¯ in pp¯ Collisions at s=1.96 TeV

T. Aaltonen, J. Adelman, T. Akimoto, B. Álvarez González et autres

We present a search for a standard model Higgs boson produced in association with a $W$ boson using $2.7\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of integrated luminosity of $p\overline{p}$ collision data taken at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$. Limits on the Higgs boson production rate are obtained …

Measurement of the tt¯ cross section in pp¯ collisions at s=1.96 TeV using dilepton events with a lepton plus track selection

T. Aaltonen, J. Adelman, T. Akimoto, B. Álvarez González et autres

This paper reports a measurement of the cross section for the pair production of top quarks in $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ at the Fermilab Tevatron. The data were collected from the CDF run II detector in a set of runs …

First measurement of the ratio of branching fractions B(Λb0→Λc+μ−ν¯μ)/B(Λb0→Λc+π−)

T. Aaltonen, J. Adelman, T. Akimoto, M. Albrow et autres

This article presents the first measurement of the ratio of branching fractions $\mathcal{B}({\ensuremath{\Lambda}}_{b}^{0}\ensuremath{\rightarrow}{\ensuremath{\Lambda}}_{c}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}{\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}})/\mathcal{B}({\ensuremath{\Lambda}}_{b}^{0}\ensuremath{\rightarrow}{\ensuremath{\Lambda}}_{c}^{+}{\ensuremath{\pi}}^{\ensuremath{-}})$.

Search for Maximal Flavor Violating Scalars in Same-Charge Lepton Pairs in pp¯ Collisions at s=1.96 TeV

T. Aaltonen, J. Adelman, T. Akimoto, M. Albrow et autres

Models of maximal flavor violation (MxFV) in elementary particle physics may contain at least one new scalar SU(2) doublet field ${\ensuremath{\Phi}}_{\mathrm{FV}}=({\ensuremath{\eta}}^{0},{\ensuremath{\eta}}^{+})$ that couples the first and third generation quarks (${q}_{1}$, ${q}_{3}$) via a Lagrangian term ${\mathcal{L}}_{\mathrm{FV}}={\ensuremath{\xi}}_{13}{\ensuremath{\Phi}}_{\mathrm{FV}}{q}_{1}{q}_{3}$. These models have a distinctive signature …
