\subsubsection{Rare decays}  The very large statistics accumulated at TLEP, including $3 \times 10^{10}$ tau pairs or muon pairs, and more than $2 \times 10^{11}$ b quarks or c quarks, should allow a new range of searches for rare phenomena and tests of conservation laws that remain to be investigated. As an illustration, more than 20,000 ${\rm B_s \to \tau^+\tau^-}$ decays would be produced, according to the Standard Model predictions: prediction:  the few thousands thousand  events observed will bring stringent constraints on new physics, which may change this branching fraction by large factors. It will be the purpose of the upcoming design study to examine and develop further the immense physics potential of TLEP-Z.
