Search for B-+/-->[K--/+pi(+/-)](D)K-+/- and upper limit on the b -> u amplitude in B-+/--> DK +/-

Abstract:
The decay of B± → [K∓π ±]DK ± is discussed. It is found that K∓π± pair originates from the decay of a D0 or D̄0. An upper limit is set on the ratio which is less than 0.026 (90% C.L.). This results in a small value of the amplitude ratio.
