Dalitz plot analyses of $B^0\to D^{-}{D}^0{K}^{+}$ and $B^{+}\to {\overline{D}}^0{D}^0{K}^{+}$ decays

Abstract

We present Dalitz plot analyses for the decays of $B$ mesons to $D^{-}{D}^0{K}^{+}$ and ${\overline{D}}^0{D}^0{K}^{+}$. We report the observation of the $D_{s1}^{\ast }(2700{)}^{+}$ resonance in these two channels and obtain measurements of the mass $M(D_{s1}^{\ast }(2700{)}^{+})=2699{}_{-7}^{+14}\mathrm{MeV}/c^2$ and of the width $\Gamma (D_{s1}^{\ast }(2700{)}^{+})=127{}_{-19}^{+24}\mathrm{MeV}$, including statistical and systematic uncertainties. In addition, we observe an enhancement in the $D^0{K}^{+}$ invariant mass around 2350--2500 MeV/$c^2$ in both decays $B^0\to D^{-}{D}^0{K}^{+}$ and $B^{+}\to {\overline{D}}^0{D}^0{K}^{+}$, which we are not able to interpret. The results are based on $429{\mathrm{fb}}^{-1}$ of data containing $471\times 10^{6}B\overline{B}$ pairs collected at the ${\rm Y}(4S)$ resonance with the BaBar detector at the SLAC National Accelerator Laboratory.
