Abstract |
Searches are presented for B-c(+) -> Dh(+)h(-) decays, where D is a charmed meson and h(+/-) is a charged pion or kaon, using pp collision data collected by the LHCb experiment corresponding to an integrated luminosity of 9 fb(-1). The decays B-c(+) -> D+K+pi(-), B-c(+) -> D*K-+(+)pi-, and B-c(+) -> D-s(+) K+K- are observed for the first time. Their branching fractions, expressed as ratios relative to that of the B-c(+) -> B-s(0)pi(+) decay, are determined to be R(B-c(+) -> D+K+pi(-)) = (1.96 +/- 0.23 +/- 0.08 +/- 0.10) x 10(-3), R(B-c(+) -> D*K-+(+)pi(-)) = (3.67 +/- 0.55 +/- 0.24 +/- 0.20) x 10(-3), B-c(+) -> D-s(+) K+K- = (1.61 +/- 0.35 +/- 0.13 +/- 0.07) x 10(-3), where the first uncertainty is statistical, the second is systematic, and the third is due to the limited precision on the D-meson branching fractions. The decay channels proceed primarily through excited K-0 or D-0 resonances or phi mesons, and open a new avenue for studies of charge-parity violation in beauty mesons. |
