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.9 p.application/pdfeng(c) The American Physical Society, 2000Reaccions nuclearsPartícules (Física nuclear)Nuclear reactionsParticles (Nuclear physics)info:eu-repo/semantics/article551543info:eu-repo/semantics/openAccess
