Kaons & Hyperons

  1. Which is the present best estimate of Vus ?
  2. Is there a consitency problem among the various Kl3 channels ?
  3. Does Kl2 compete with Kl3 ? Which improvements can we expect in the next few years on K->0 and K->pi form factors ?
  4. Does Hyperon decays allow a precise extraction of Vus ?
