 Title: Anomalous couplings of the third generation in rare B Decays Author: Burdman, G.González García, Ma. ConcepciónNovaes, S. F. Keywords: Reaccions nuclearsPartícules (Física nuclear)Nuclear reactionsParticles (Nuclear physics) Issue Date: 2000 Publisher: The American Physical Society Abstract: We study the potential effect of anomalous couplings of the third generation quarks to gauge bosons in rare B decays. We focus on the constraints from flavor changing neutral current processes such as $b\to s\gamma$ and $b\to s \ell^+\ell^-$. We consider both dimension-four and dimension-five operators and show that the latter can give large deviations from the standard model in the still unobserved dilepton modes, even after the bounds from $b\to s\gamma$ and precision electroweak observables are taken into account.
