Study of the decay Ds+ → KS0 KS0 π+ and observation of an isovector partner to f0 (1710)
(American Physical Society, 2022)
Using e+e-annihilation data corresponding to a total integrated luminosity of 6.32 fb-1 collected at center-of-mass energies between 4.178 and 4.226 GeV with the BESIII detector, we perform an amplitude analysis of the ...
Measurement of the e(+) e(-) -> omega pi(0)pi(0) cross section at center-of-mass energies from 2.0 to 3.08 GeV
(AMER PHYSICAL, 2022)
The cross section of the process e(+)e(-) -> omega pi(0)pi(0) is measured at nineteen center-of-mass energies from 2.0 to 3.08 GeV using data collected with the BESIII detector at the BEPCII storage ring. A resonant structure ...
Measurement of the branching fraction of the doubly cabibbo-suppressed decay D0 →k+π-π0 and search for D0 →k+π-π0π0
(American Physical Society, 2022)
Using 2.93 fb-1 of e+e- collision data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we present a measurement of the branching fraction of the doubly Cabibbo-suppressed (DCS) decay D0→K+π-π0 ...
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 ...
Search for invisible decays of the Λ baryon
(American Physical Society, 2022)
A search for invisible decays of the Λ baryon is carried out in the process J/ψ→ΛΛ¯ based on (1.0087±0.0044)×1010 J/ψ events collected with the BESIII detector located at the BEPCII storage ring. No signals are found for ...
