Measurements of the branching fractions for D+ -> (KSKSK+)-K-0-K-0+, (KSKS0)-K-0 pi + and D-0 -> (KSKS0)-K-0, (KSKSKS0)-K-0-K-0
(Elsevier Science, 2017)
By analyzing 2.93 fb(-1) of data taken at the psi(3770) resonance peak with the BESIII detector, we measure the branching fractions for the hadronic decays D+ -> (KSKSK+)-K-0-K-0, D+ -> (KSKS0)-K-0 pi(+), D-0 -> (KSKS0)-K-0 ...
An improved limit for ?ee of X(3872) and ?ee measurement of ?(3686)
(Elsevier, 2015)
Using the data sets taken at center-of-mass energies above 4 GeV by the BESIII detector at the BEPCII storage ring, we search for the reaction e+e-??ISRX(3872)??ISR?+?-J/? via the Initial State Radiation technique. The ...
Measurement of yCP in D0-D0 oscillation using quantum correlations in e+e- ? D0D0 at ?s = 3.773 GeV
(Elsevier B.V., 2015)
We report a measurement of the parameter yCP in D0-D-0 oscillations performed by taking advantage of quantum coherence between pairs of D0D-0 mesons produced in e+e- annihilations near threshold. In this work, doubly-tagged ...
Measurement of the e+e- › ?+?- cross section between 600 and 900 MeV using initial state radiation
(Elsevier, 2016)
We extract the e+e-›?+?- cross section in the energy range between 600 and 900 MeV, exploiting the method of initial state radiation. A data set with an integrated luminosity of 2.93 fb-1 taken at a center-of-mass energy ...
Measurement of the absolute branching fraction for Lambda(+)(c) -> Lambda mu(+)nu(mu)
(Elsevier Science, 2017)
We report the first measurement of the absolute branching fraction for Lambda(+)(c) -> Lambda mu(+)nu(mu).This measurement is based on a sample of e+e(-) annihilation data produced at a center-of-mass energy root s = 4.6 ...
Measurement of the leptonic decay width of J/psi using initial state radiation
(Elsevier, 2016)
Using a data set of 2.93 fb(-1) taken at a center-of-mass energy of root s = 3.773 GeV with the BESIII detector at the BEPCII collider, we measure the process e(+) e(-) -> J/psi gamma -> mu(+)mu(-)gamma and determine the ...
Measurement of branching fractions for D meson decaying into ϕ meson and a pseudoscalar meson
(Elsevier B.V., 2019)
The four decay modes D0→ϕπ0, D0→ϕη, D+→ϕπ+, and D+→ϕK+ are studied by using a data sample taken at the centre-of-mass energy s=3.773 GeV with the BESIII detector, corresponding to an integrated luminosity of 2.93 fb−1. The ...
Dark photon search in the mass range between 1.5 and 3.4 GeV/c
(Elsevier Science, 2017)
Using a data set of 2.93 fb taken at a center-of-mass energy root s = 3.773 GeV with the BESIII detector at the BEPCII collider, we perform a search for an extra U(1) gauge boson, also denoted as a dark photon. We examine ...
