      • Bs→μμ ∼ 3.8±1.0 x10-9   in SM
      • Bd→μμ ∼ 1.0±0.6 x10-10   in SM
      SUSY enhances it by 101∼103
      90%CL upper limits with 171pb-1
        • BR(Bs→μμ) < 5.8x10-7 → 1x10-8 expected for 2fb-1
        • BR(Bd→μμ) < 1.5x10-7 → 4x10-8 expected for 2fb-1

      Similarly
      • D0 → μμ ∼ 10-13   in SM
      R-violating SUSY enhances it to ∼ 10-6
      90%CL upper limits with 69pb-1
        • BR(D0→μμ) < 2.4x10-6 ; pretty close
