Precise measurements of branching fractions for D-s(+) meson decays to two pseudoscalar mesons
(Springer, 2020)
We measure the branching fractions for seven D-s(+) two-body decays to pseudoscalar mesons, by analyzing data collected at root s = 4:178 similar to 4:226 GeV with the BESIII detector at the BEPCII collider. The branching ...
Observation of the decays chi(cJ) -> Sigma(0)(p)over-barK(+) + c.c. (J=0,1,2)
(Amer Physical Soc., 2020)
The decays chi(cJ) -> Sigma(0)(p) over barK(+) + c.c. (J = 0,1,2) are studied via the radiative transition psi(3686) ->gamma chi(cJ) based on a data sample of (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the ...
Observation of the semimuonic decay D+ -> omega mu(+)upsilon(mu)
(Amer Physical Soc., 2020)
We report the first observation of the semimuonic decay D+ -> omega mu(+)upsilon(mu) using an e(+)e(-) collision data sample corresponding to an integrated luminosity of 2.93 fb(-1) collected with the BESIII detector at a ...
Measurement of the Cross Section for e(+)e(-) -> Xi(-)Xi(+)and Observation of an Excited Xi Baryon
(Amer Physical Soc., 2020)
Using a total of 11.0 fb(-1) of e(+)e(-) collision data with center-of-mass energies between 4.009 and 4.6 GeV and collected with the BESIII detector at BEPCII, we measure fifteen exclusive cross sections and effective ...
Search for the rare decay eta ' -> pi(0)pi(0)pi(0)pi(0) at BESIII
(Amer Physical Soc., 2020)
Using a sample of 1.31 x 10(9) J/psi events collected with the BESIII detector, we perform a search for the rare decay if eta' -> 4 pi(0) via J/psi -> gamma eta'. No significant eta' signal is observed in the 4 pi(0) ...
Measurement of the Born cross sections for e(+)e(-) -> D-s(+) D-s1 (2460)(-) +c.c. and e(+) e(-) -> D-s*(+) D-s1 (2460)(-)( )+ c.c.
