Abstract
We review some recent measurements of B meson decays that involve leptons in the final states and that are sensitive to physics beyond the Standard Model, such as the electroweak penguin decays B → Xsℓ+ℓ−, the Lepton Number Violating process B → Xℓ±ℓ′± and the tree-level dominated decay with τ leptons: B → τντ and B → D(∗)τντ.
Highlights
The BaBar experiment has collected about 470·106 couple of BB events from the Υ(4S ) decays
We review some recent measurements of B meson decays that involve leptons in the final states and that are sensitive to physics beyond the Standard Model, such as the electroweak penguin decays B → Xs + −, the Lepton Number Violating process B → X ± ± and the tree-level dominated decay with τ leptons: B → τντ and B → D(∗)τντ
No relevant deviations from the Standard Model (SM) have yet been found with the current statistics by BaBar and Belle, it is of paramount importance to continue to search for New Physics (NP) sign through indirect virtual contributions in the B decays
Summary
The BaBar experiment has collected about 470·106 couple of BB events from the Υ(4S ) decays. We review some recent measurements of B meson decays that involve leptons in the final states and that are sensitive to physics beyond the Standard Model, such as the electroweak penguin decays B → Xs + −, the Lepton Number Violating process B → X ± ± and the tree-level dominated decay with τ leptons: B → τντ and B → D(∗)τντ. We present some recent result from BaBar on B meson decays in channels with leptons in the final state.
