Precision measurements of , the pseudoscalar decay constant , and the quark mixing matrix element
BESIII Collaboration, M. Ablikim, M. N. Achasov +375
We report a measurement of the branching fraction based on 2.92 of data a…
Observation of a charged (DD*bar)- mass peak in e+e- --> pi+ (DD*bar)- at Ecm=4.26 GeV
M. Ablikim, M. N. Achasov, O. Albayrak +1
We report on a study of the process e+e- --> pi+(D D*bar)- at Ecm=4.26 GeV using a 525 /pb data sample collected with the BESIII detector at the BEPCII storage ring. A distinct cha…
Observation of at BESIII
BESIII collaboration, M. Ablikim, M. N. Achasov +372
With data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of-mass energies from 4.009 to 4.420 GeV, the process …
Observation of a structure at 1.84 GeV/c in the mass spectrum in decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +362
With a sample of 225.3 million events taken with the BESIII detector, the decay is analyzed. A structure at 1.84 GeV/c is observed in the $3(π…
Measurement of and
BESIII Collaboration, M. Ablikim, M. N. Achasov +361
Based on a sample of 225.3 million J/ψevents accumulated with the BESIII detector at the BEPCII, the decays of η' to pi+pi-l+l- are studied via J/ψto γη'. A clear η' signal is obse…
Evidence for η_{c}(2S) in ψ(3686) \to γK_{S}^{0}K^{\pm}π^{\mp}π^{+}π^{-}
The BESIII Collaboration, M. Ablikim, M. N. Achasov +346
We search for the M1 radiative transition ψ(3686) \to γη_{c}(2S) by reconstructing the exclusive η_{c}(2S) \to K_{S}^{0}K^{\pm}π^{\mp}π^{+}π^{-} decay using 1.06 \times 10^8 ψ(3686…
