Measurements of absolute branching fractions for D mesons decays into two pseudoscalar mesons

Measurements of absolute branching fractions for D mesons decays into two pseudoscalar mesons

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 s=3.773 GeV with the BESIII detector operating at the BEPCII storage rings, we measure the absolute branching fractions of the two-body hadronic decays D+→π+π0, K+π0, π+η, K+η, π+...

Zusammenfassung: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 s=3.773 GeV with the BESIII detector operating at the BEPCII storage rings, we measure the absolute branching fractions of the two-body hadronic decays D+→π+π0, K+π0, π+η, K+η, π+η′, K+η′, KS0π+, KS0K+, and D0→π+π−, K+K−, K∓π±, KS0π0, KS0η, KS0η′. Our results are consistent with previous measurements within uncertainties. Among them, the branching fractions for D+→π+π0, K+π0, π+η, π+η′, KS0π+, KS0K+ and D0→KS0π0, KS0η, KS0η′ are determined with improved precision compared to the world average values.
