First Measurement of the Form Factors in D-s(+) -> K(0)e(+)nu(e) and D-s(+) -> K*(0)e(+)nu(e) Decays
(Amer Physic Soc., 2019)
We report on new measurements of Cabibbo-suppressed semileptonic D-s(broken vertical bar) decays using 3.19 fb(-1) of e(broken vertical bar)e(-) annihilation data sample collected at a center-of-mass energy of 4.178 GeV ...
Measurement of the branching fraction for ?(3770) › ??c0
(Elsevier, 2016)
By analyzing a data set of 2.92fb-1 of e+e- collision data taken at s=3.773GeV and 106.41×106 ?(3686) decays taken at s=3.686GeV with the BESIII detector at the BEPCII collider, we measure the branching fraction and the ...
First measurement of e(+)e(-) -> pK(S)(0)(n)over-barK(-) + c.c. above open charm threshold
(Amer Physical Soc., 2018)
The process e(+)e(-) -> pK(S)(0)(n) over barK(-) + c.c. and its intermediate processes are studied for the first time, using data samples collected with the BESIII detector at BEPCII at center-of-mass energies of 3.773, ...
