Rare decays are very sensitive probes for phenomena beyond the Standard Model, complementary to direct searches. In the Standard Model, rare decays are loop suppressed and may receive significant contributions from new particles, if these exist. Particularly interesting are b->sll transitions, which allow tests of lepton universality to be performed. Very rare decays such as B(s)->ll are...

21. Measurement of the branching fractions $BF(\tau^- \to K^- n\pi^0 \nu_\tau)$, $n=0,1,2,3$, and $BF(\tau^- \to \pi^- n\pi^0 \nu_\tau)$, $n=3,4$.

We report the measurements of the branching fractions of the decays $\tau^- \to K^- n\pi^0 \nu_\tau$, $n=0,1,2,3$, and $\tau^- \to \pi^- n\pi^0 \nu_\tau$, $n=3,4$. The measurements are based on a data sample of 435 million tau pairs produced in $e^+e^-$ collisions at and near the Y(4S) peak and collected with the $BABAR$ detector in 1999--2008. Additional systematic studies have been completed...

Charged Lepton flavour violation (LVF) is a striking signature of potential beyond the Standard Model physics. Searches for LFV with the ATLAS detector are reported in channels focusing on the decay of the Higgs boson, the Z boson and of a heavy neutral gauge boson, Z', using
pp collisions data with a center of mass energy of 13 TeV

Talk

Lepton flavour violation effects are predicted in several extensions of the Standard Model (SM), including supersymmetric versions of Grand Unification Theories, at a measurable level. Since the SM background, even including neutrino oscillations and mixing, is completely negligible the observation of such effects would be a strong evidence for New Physics beyond the SM, while a non...

The PIENU experiment at TRIUMF aims to measure the branching ratio, R_e/μ = Γ(π⁺ → e⁺ν(γ))/Γ(π⁺ → μ⁺ν(γ)), with 0.1% of the precision; providing the most precise test of the lepton universarity. The collaboration collected physics data during 2009--2012, and the result of...
