چکیده
By analyzing an electron-positron collision data sample corresponding to integrated luminosity of 2.93 fb?1 taken at the center-of-mass energy 3.773 GeV with BESIII detector, we obtain for first time absolute branching fractions seven D0 and D+ hadronic decay modes search D0?KS0KS0?0 much improved sensitivity. The results are B(D0?KS0?0?0?0)=(7.64±0.30±0.29)×10?3, B(D0?K??+?0?0?0)=(9.54±0.30±0.31)×10?3, B(D0?KS0?+???0?0)=(12.66±0.45±0.43)×10?3, B(D+?KS0?+?0?0)=(29.04±0.62±0.87)×10?3, B(D+?KS0?+?+???0)=(15.28±0.57±0.60)×10?3, B(D+?KS0?+?0?0?0)=(5.54±0.44±0.32)×10?3, B(D+?K??+?+?0?0)=(4.95±0.26±0.19)×10?3, B(D0?KS0KS0?0)<1.45×10?4 90% confidence level.

Absolute measurement of hadronic branching fractions of the Ds+ meson.
The branching fractions of D(s)(+/-) meson decays serve to normalize many measurements of processes involving charm quarks. Using 298 pb(-1) of e(+)e(-) collisions recorded at a center of mass energy of 4.17 GeV, we determine absolute branching fractions for eight D(s)(+/-) decays with a double tag technique. In particular we determine the branching fraction B(D(s)(+)-->K(-)K(+}pi(+))=(5.50+/-0...

متن کاملDirect measurements of charmed-D-meson hadronic branching fractions.
A new technique is applied to data collected at the +(3770) resonance to derive charmed D meson branching fractions without relying on the measurement of D production cross sections. Measurements are presented for three decay modes of the Do (K-n+, K-?r-w+r+ and K-7r+r ") and four decay modes of the D+ (K-7r+rr+, K-x+r+~~, Kt?r+ and Kfr+7r "). The resulting branching fractions are significantly...
متن کاملHadronic Charmed Meson Decays Involving Tensor Mesons
Charmed meson decays into a pseudoscalar meson P and a tensor meson T are studied. The charm to tensor meson transition form factors are evaluated in the Isgur-Scora-Grinstein-Wise (ISGW) quark model. It is shown that the Cabibbo-allowed decay D+ s → f2(1270)π is dominated by the W -annihilation contribution and has the largest branching ratio in D → TP decays. We argue that the Cabibbo-suppres...
