Charge/Theme of the session:
 Please see first the
General charges for all experimental talks in WG4
 In addition, please consider for the experimental talks:
 What are the present limitations in the Dalitz analysis ? How can we improve on these ?
 For the theoretical talks:
 Understanding of the πK modes: How well can they be used to determine γ ? What is the role and are the uncertainties of the contribution from electroweak penguins ?
 What can be learnt in addition from πK* and ρK/K* modes ?
