Publications of the Rare Decays Working Group

Searches for and studies of non-hadronic decays of flavoured particles (except charm), including

• Fully leptonic decays: $B_{(s)} \to \mu\mu$, $B_{s} \to \tau\tau$, $B \to \mu\mu\mu\mu$
• Electroweak penguin decays: $B \to K^{\ast 0}\mu\mu$, $B \to K^{\ast 0}ee$, $\Lambda_b \to \Lambda\mu\mu$, $B \to K\mu\mu$, $B \to \pi\mu\mu$, (and similar with $\phi$, $K_1$, $\rho$, etc.)
• Radiative decays: $B \to K^{\ast}\gamma$, $B_s \to \phi\gamma$, $\Lambda_b \to \Lambda^{(\ast)}\gamma$, $B \to K_1\gamma$, $B \to \rho\gamma$
• Lepton flavour violation: $\tau \to \mu\mu\mu$, $B \to \tau\mu$, $\Upsilon \to e\mu$
• Lepton number violation: $\tau \to p\mu\mu$, $\tau\to \mu\pi\pi$, $B\to K\mu\mu$, $B \to \pi\mu\mu$, $B\to D^{(\ast)}\mu\mu$ (same sign muons)
• Decays of light flavoured particles, such as $K^0_S \to \mu\mu$ and hyperon decays (including exotic signals)
