Amplitude Analysis and Branching-Fraction Measurement of D-s(+) -> pi(+)pi(0)eta '
(Springer, 2022)
Using data collected with the BESIII detector in e(+)e(-) collisions at center-of-mass energies between 4.178 and 4.226 GeV and corresponding to 6.32 fb(-1) of integrated luminosity, we report the amplitude analysis and ...
Measurement of e(+)e(-)-> K+K-pi(0) Cross Section and Observation of a Resonant Structure
(Springer, 2022)
Based on e(+)e(-) collision data collected by the BESIII detector at the BEPCII collider at center-of-mass energies from 2.000 to 3.080 GeV, a partial-wave analysis is performed for the process e(+)e(-)-> K+K-pi(0). The ...
Measurements of Absolute Branching Fractions of D-0 -> K-L(0)phi, K-L(0)eta, K-L(0)omega, and K-L(0)eta '
(Amer Physical Soc., 2022)
We report the first measurements of the absolute branching fractions of D-0 -> K-L(0)phi, D-0 -> K-L(0)eta, D-0 -> K-L(0)omega, and D-0 -> K-L(0)eta', by analyzing 2.93 fb(-1) of e(+) e(-) collision data taken at a ...
Search for a massless dark photon in Λc+ →pγ′ decay
(American Physical Society, 2022)
A search for a massless dark photon γ′ is conducted using 4.5 fb-1 of e+e- collision data collected at center-of-mass energies between 4.600 and 4.699 GeV with the BESIII detector at BEPCII. No significant signal is observed, ...
Cross section measurements of the processes e(+)e(-) -> omega pi(0) and omega eta at center-of-mass energies between 3.773 and 4.701 GeV
(SPRINGER, 2022)
The Born cross sections of the processes e(+)e(-) -> omega pi(0) and e(+)e(-) -> omega eta are measured at center-of-mass energies between 3.773 and 4.701 GeV using a total integrated luminosity of 22.7 fb(-1) collected ...
Observation of D0(+) -> K-S(0)pi(0(+))omega and improved measurement of D-0 -> K- pi(+)omega
(AMER PHYSICAL SOC, 2022)
By analyzing an e(+)e(-) annihilation data sample with an integrated luminosity of 2.93 fb(-1) taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, we determine the absolute branching fractions of the ...
First Measurement of Polarizations in the Decay D-0 -> omega phi
(Amer Physical Soc., 2022)
Using a data sample corresponding to an integrated luminosity of 2.93 fb(-1) collected at a center-of-mass energy root s = 3.773 GeV by the BESIII detector, the decay D-0 -> omega phi is observed for the first time. The ...
