Determination of the Lambda(c)+ spin via the reaction e(+)e(-) -> Lambda(c)(Lambda)over-bar(c)
(Amer Physical Soc., 2021)
We report on a comparison of two possible Lambda(+)(c) spin hypotheses, J = 1/2 and 3/2, via the process e(+)e(-) -> Lambda(c)(Lambda) over bar (c) using the angular distributions of Lambda(+)(c) decays into pK(S)(0), ...
Measurement of the Absolute Branching Fraction of D-s(+) -> tau(+)nu(tau) via tau(+) -> e(+)nu(e)(nu)over-bar(tau)
(Amer Physical Soc., 2021)
Using a dataset of 6.32 fb(-1) of e(+)e(-) annihilation data collected with the BESIII detector at center-ofmass energies between 4178 and 4226 MeV, we have measured the absolute branching fraction of the leptonic decay ...
Observation of a Near-Threshold Structure in the K+ Recoil-Mass Spectra in e(+) e(-) -> K+ (D-s(-) D*(0) + D-s* - D-0)
(Amer Physical Soc., 2021)
We report a study of the processes of e(+)e(-) -> K+Ds- D*(0) and K+Ds* D-0 based on e(+)e(-) annihilation samples collected with the BESIII detector operating at BEPCII at five center-of-mass energies ranging from 4.628 ...

(Amer Physical Soc., 2021)
We report new measurements of the branching fraction B(Dv), where lis either mu or tau (-> pi), based on 6.32 fbof electron-positron annihilation data collected by the BESIII experiment at six center-of-mass energy points ...
Cross Section Measurement of e(+)e(-) -> p(p)over-bar eta and e(+)e(-) -> p(p)over-bar Omega at Center-of-Mass Energies Between 3.773 GeV and 4.6 GeV
(Amer Physical Soc., 2021)
Based on 14.7 fb(-1) of e(+)e(-) annihilation data collected with the BESIII detector at the BEPCII collider at 17 different center-of-mass energies between 3.7730 GeV and 4.5995 GeV, Born cross sections of the two processes ...
