    3. BRANCHING RATIO

      • non-W decay → H+ ? (δR/R=9% with 2fb-1 expected)
      • non-b decay → non-SM (δR/R=2.8% with 2fb-1 expected)
            Present result with 108pb-1 ⇒ B(t→Wb)=0.54+0.49 -0.39
            → much much much more data needed !

      • FCNC (t → u/c/γ/Z/g) ; SM=10-10 ⇒ Any observation → new phyics ?
        Sensitivity
                t → c/u + γ < 0.28% with 2fb-1 expected
                t → c/u + Z < 1.3% with 2fb-1 expected
      • However no new public results released yet
