Description
Flavour changing neutral current B meson decays, such as $B^{\pm}\to K^{\pm}\tau^{+}\tau^{-}$, are a powerful probe of physics beyond the Standard Model (SM). Comparison of the experimentally measured rate to SM predictions can provide evidence for new physics. Deviations from the SM prediction might arise due to hypothetical heavy particles such as Supersymmetric quarks or bosons or a charged Higgs. Similarly, $B^{\pm}\to K^{\pm}\ell^{+}\ell^{-}$ , where $\ell= e^{+}$ or $\mu^{+}$, has been recently measured by as well as other experiments. The search for $B^{\pm}\to K^{\pm}\tau^+\tau^-$ is specifically interesting, because it involves third-generation leptons, which have greater potential sensitivity to new physics. The search for this rare decay is performed using a sample of 471 million $B{\kern 0.18em\overline{\kern -0.18em B}{}}$, collected with the detector at the PEP-II $e^{+}e^{-}$ collider. The analysis approach is discussed, along with the expected results.
