Charge/Theme of the session:

  1. Please see the

    General charges for all experimental talks in WG4

  2. For the theoretical talks:

    • How trustable are theoretical calculations regarding penguin pollution ? In particular, can they be used to replace potentially insufficient measurements like the direct asymmetry in B→π0π0 ?
    • How large are isospin breaking effects ? Are there ways that these errors can be reduced ?
    • How important is scalar background in B+→ρ+ρ0 ?
