摘要

Using 2.93 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 14 hadronic D0(+) decays to exclusive final states with an e.g., D-0 -> K-pi(+)eta, K-S(0)pi(0)eta, K+K-eta, (KSKS0)-K-0 eta, K-pi(+)pi(0)eta, K-S(0)pi(+)pi(-)eta, K-S(0)pi(0)pi(0)eta, and pi(+)pi(-)pi(0)eta; D+ -> K-S(0)pi(+)eta, (KSK+)-K-0 eta, K-pi(+)pi(+)eta, K-S(0)pi(+)pi(0)eta, pi(+)pi(+)pi(-)eta, and pi(+)pi(0)pi(0)eta. Among these decays, the D-0 -> K-pi(+)eta and D+ -> K-S(0)pi(+)eta decays have the largest branching fractions, which are B(D-0 -> K-pi(+)eta) = (1.853 +/- 0.025(stat) +/- 0.031(syst))% and B(D+ -> K-S(0)pi(+)eta) = (1.309 +/- 0.037(star)+/- 0.031(syst))%, respectively. The charge-parity asymmetries for the six decays with highest event yields are determined, and no statistically significant charge-parity violation is found.
