- We report measurements of the ratios of branching fractions for B-& iota; over bar Do ⠂ thorn & pi;e thorn & nu;e and B-& iota; over bar Do ⠂ thorn & pi; thorn & pi;-e thorn & nu;e relative to B-& iota; over bar D ⠂e thorn & nu;e decays with e 1/4 e, & mu;. These results are obtained from a data sample that contains 772 x 106BB over bar pairs collected near the ϒo4S thorn resonance with the Belle detector at the KEKB asymmetric energy e thorn e- collider. Fully reconstructing both B mesons in the event, we obtain BoB0-& iota; over bar D0 & pi;-e thorn & nu;e thorn BoB0-& iota;D ⠂-e thorn & nu;e thorn 1/4 o7.23 ⠃ 0.36 ⠃ 0.14 thorn %, BoB thorn -& iota;D-& pi; thorn e thorn & nu;e thorn BoB thorn -& iota; over bar D ⠂0e thorn & nu;e thorn 1/4 o6.78 ⠃ 0.24 ⠃ 0.18 thorn %, BoB0-& iota; over bar D ⠂0 & pi;-e thorn & nu;e thorn BoB0-& iota;D ⠂-e thorn & nu;e thorn 1/4 o11.10 ⠃0.48 ⠃0.23 thorn %, BoB thorn BoB thorn -& iota;-& iota;D ⠂- over bar D ⠂0 & pi; thorn e thorn e thorn & nu;e & nu;e thorn thorn 1/4 o9.50 ⠃0.33 ⠃0.34 thorn %, BoB0-& iota;D-& pi; thorn & pi;-e thorn & nu;e thorn BoB0-& iota;D ⠂-e thorn & nu;e thorn 1/4 o2.91 ⠃0.37 ⠃0.26 thorn %, BoB thorn -& iota; over bar D0 & pi; thorn & pi;-e thorn & nu;e thorn BoB thorn -& iota; over bar D ⠂0e thorn & nu;e thorn 1/4o3.10 ⠃0.26 ⠃0.22 thorn %, BoB0-& iota;D ⠂-& pi; thorn & pi;-e thorn & nu;e thorn BoB0-& iota;D ⠂-e thorn & nu;e thorn 1/4o0.99 ⠃0.43 ⠃ 0.20 thorn %, BoB thorn -& iota; over bar D ⠂0 & pi; thorn & pi;-e thorn & nu;e thorn BoB thorn -& iota; over bar D ⠂0e thorn & nu;e thorn 1/4 o1.25 ⠃ 0.27 ⠃ 0.15 thorn %, where the uncertainties are statistical and system-atic, respectively.
