Abstract
B --> pi l nu decay is studied in the effective theory of heavy quark with infinite mass limit. The leading order heavy flavor-spin independent universal wave functions which parametrize the relevant matrix elements are evaluated via light cone sum rule method in the effective theory. The important quark mixing matrix element |V_{ub}| is then extracted via B --> pi l nu decay mode.
