Determining the unitarity triangle angle gamma with a four-body amplitude analysis of B-+/- -> (K+K-pi(+)pi(-))(D)K-+/- decays

Abstract:
We explain how a four-body amplitude analysis of the D decay products in the mode B± → (K+ K- π+ π-)D K± is sensitive to the unitarity triangle angle γ. We present results from simulation studies which show that a precision on γ of 15° is achievable with 1000 events and assuming a value of 0.10 for the parameter rB. © 2007 Elsevier B.V.
