New physics effects in tree-level decays
Joachim Brod, Alexander Lenz, Gilberto Tetlalmatzi-Xolocotzi +1
We critically review the assumption that no new physics is acting in tree-level -meson decays and study the consequences for the ultimate precision in the direct determination o…
Electroweak effects in the extraction of the CKM angle from decays
Joachim Brod
The angle of the standard CKM unitarity triangle can be determined from tree-level -meson decays essentially without hadronic uncertainties. We calculate the second-order el…
Probing anomalous interactions with rare meson decays
Joachim Brod, Admir Greljo, Emmanuel Stamou +1
Anomalous couplings of the boson to top quarks are only marginally constrained by direct searches and are still sensitive to new particle dynamics at the TeV scale. Employing a…
Stealth QCD-like Strong Interactions and the t-tbar Asymmetry
Joachim Brod, Jure Drobnak, Alexander L. Kagan +2
We show that a new strongly interacting sector can produce large enhancements of the t-tbar asymmetries at the Tevatron. The Standard Model is extended by a new vector-like flavor…
