Measurement of the branching fraction for ψ(3770) → γχc0
By analyzing a data set of 2.92fb−1 of e+e− collision data taken at s=3.773GeV and 106.41×106 ψ(3686) decays taken at s=3.686GeV with the BESIII detector at the BEPCII collider, we measure the branching fraction and the ...
Measurement of azimuthal asymmetries in inclusive charged dipion production in e + e − annihilations at √ s = 3.65 GeV
(APS Physics, 2016)
We present a measurement of the azimuthal asymmetries of two charged pions in the inclusive process e(+) e(-) -> pi pi X based on a data set of 62 pb(-1) at the center-of-mass energy of 3.65 GeV collected with the SESIII ...
Search for the weak decay η′→K±π∓ and precise measurement of the branching fraction B(J/ψ→φη′)
We present the first search for the rare decay of η′ into K±π∓ in J/ψ→ϕη′, using a sample of 1.3×109 J/ψ events collected with the BESIII detector. No significant signal is observed, and the upper limit at the 90\% confidence ...
Measurement of the absolute branching fraction of D+ → K¯ 0e +νe via K¯ 0 → π 0π 0 *
By analyzing 2.93 fb−1 data collected at the center-of-mass energy √ s = 3.773 GeV with the BESIII detector, we measure the absolute branching fraction of the semileptonic decay D + → K¯ 0 e +νe to be B(D+ → K¯ 0 e +νe) = ...
