Abstract / Description of output

Using proton-proton collision data collected by the LHCb experiment at s√= 7 TeV, corresponding to an integrated luminosity of 1.0 fb−1, the ratio of branching fractions of the B0→D∗−π+π−π+ decay relative to the B0→D∗−π+ decay is measured to be
The Cabibbo-suppressed decay B0→D∗−K+π−π+ is observed for the first time and the measured ratio of branching fractions is
A search for orbital excitations of charm mesons contributing to the B0→D∗−π+π−π+ final state is also performed, and the first observation of the B0→Dˉ1(2420)0π+π− decay is reported with the ratio of branching fractions
where the numerator represents a product of the branching fractions B(B0→Dˉ1(2420)0π−π+) and B(Dˉ1(2420)0→D∗−π+).
