Using $2.93,rm fb^{-1}$ of $e^+e^-$ collision data taken at a center-of-mass energy of 3.773,GeV with the BESIII detector, we report the first measurements of the absolute branching fractions of fourteen hadronic $D^{0(+)}$ decays to exclusive final states with an $eta$, e.g., $D^0to K^-pi^+eta$, $K^0_Spi^0eta$, $K^+K^-eta$, $K^0_SK^0_Seta$, $K^-pi^+pi^0eta$, $K^0_Spi^+pi^-eta$, $K^0_Spi^0pi^0eta$, and $pi^+pi^-pi^0eta$; $D^+to K^0_Spi^+eta$, $K^0_SK^+eta$, $K^-pi^+pi^+eta$, $K^0_Spi^+pi^0eta$, $pi^+pi^+pi^-eta$, and $pi^+pi^0pi^0eta$. Among these decays, the $D^0to K^-pi^+eta$ and $D^+to K^0_Spi^+eta$ decays have the largest branching fractions, which are $mathcal{B} (D^0to K^-pi^+eta )=(1.853pm0.025_{rm stat}pm0.031_{rm syst})%$ and $mathcal{B}(D^+to K^0_Spi^+eta)=(1.309pm0.037_{rm stat}pm0.031_{rm syst})%$, respectively. We also determine the $CP$ asymmetries for the six decays with highest event yields. No evidence of $CP$ violation is found.
Based on 2.93~fb$^{-1}$ $e^+e^-$ collision data taken at center-of-mass energy of 3.773 GeV by the BESIII detector, we report the measurements of the absolute branching fractions of $D^0to K^+K^-pi^0pi^0$, $D^0to K^0_SK^0_Spi^+pi^-$, $D^0to K^0_SK^-p
Using $567rm{pb}^{-1}$ of $e^+e^-$ collisions recorded at $sqrt{s}=4.599rm{GeV}$ with the BESIII detector, we report first measurements of absolute hadronic branching fractions of Cabibbo-favored decays of the $Lambda_{c}^{+}$ baryon with a double-ta
Using a data sample of $e^+e^-$ collision data with an integrated luminosity of 2.93 fb$^{-1}$ taken at the center-of-mass energy $sqrt s= 3.773$~GeV with the BESIII detector operating at the BEPCII storage rings, we measure the absolute branching fr
By analyzing 2.93 fb$^{-1}$ of $e^+e^-$ annihilation data taken at the center-of-mass energy $sqrt s=$ 3.773 GeV with the BESIII detector, we determine the branching fractions of the inclusive decays $D^+tophi X$ and $D^0tophi X$ to be $(1.135pm0.034
Utilizing the full CLEO-c data sample of 818 pb$^{-1}$ of $e^+e^-$ data taken at the $psi(3770)$ resonance, we update our measurements of absolute hadronic branching fractions of charged and neutral $D$ mesons. We previously reportedresults from subs
