Abstract:

We present a new measurement of the B+ meson differential cross section dσ/dpT at s=1960GeV. The data correspond to an integrated luminosity of 739pb-1 collected with the upgraded CDF detector (CDF II) at the Fermilab Tevatron collider. B+ candidates are reconstructed through the decay B+→J/ψK+, with J/ψ→μ+μ-. The integrated cross section for producing B+ mesons with pT≥6GeV/c and |y|≤1 is measured to be 2.78±0.24μb. © 2007 The American Physical Society.

Multi-W Events at LHC from a Warped Extra Dimension with Custodial Symmetry

Abstract:

Randall-Sundrum models based on SU(2)_L * SU(2)_R with custodial symmetry are compelling frameworks for building alternative models of electroweak symmetry breaking. A particular feature of these models is the likely presence of light Kaluza-Klein fermions related to the right-handed top quark. These can be as light as a few hundred GeV and still compatible with EW precision constraints. In this article, we study the detectability of four-W final states at the LHC, which arise from the pair-production and tW decay of light Kaluza-Klein bottom quarks as well as light Kaluza-Klein quarks carrying electric charge 5/3.
