College Pk: American Physical Soc, v. 61, n. 11, 9 p., 2000.0556-2821http://hdl.handle.net/11449/23468We study the potential effects 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-->s gamma and b -->sl(+)l(-). 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-->s gamma and precision electroweak observables are taken into account.9engArtigo10.1103/PhysRevD.61.114016WOS:000087284800038Acesso restritoWOS000087284800038.pdf
