Measurement of e(+)e(-) -> D(D)over-bar cross sections at the psi(3770) resonance
(Iop Publishing, 2018)
We report new measurements of the cross sections for the production of D (D) over bar final states at the psi(3770) resonance. Our data sample consists of an integrated luminosity of 2.93 fb(-1) of e(+)e(-) annihilation ...
Observation of D0(+) -> K-S(0)pi(0(+))eta ' and improved measurement of D-0 -> K-pi(+)eta '
(Amer Physical Soc., 2018)
By analyzing an e(+)e(-) data sample corresponding to an integrated luminosity of 2.93 fb(-1) taken at a centerof- mass energy of 3.773 GeV with the BESIII detector, we measure the branching fractions of the Cabibbofavored ...
Search for a strangeonium-like structure Z(s) decaying into phi pi and a measurement of the cross section e(+)e(-) -> phi pi pi
(Amer Physical Soc., 2019)
Using a data sample of e(+)e(-) collision data corresponding to an integrated luminosity of 108 pb(-1) collected with the BESIII detector at a center-of-mass energy of 2.125 GeV, we study the process e(+)e(-) -> phi pi pi ...
Observation of D-s(+) -> p(n)over-bar and confirmation of its large branching fraction
(Amer Physic Soc., 2019)
The baryonic decay D-s(+) -> p (n) over bar is observed, and the corresponding branching fraction is measured to be (1.21 +/- 0.10 +/- 0.05) x 10(-3), where the first uncertainty is statistical and second systematic. The ...
Measurement of the integrated Luminosities of cross-section scan data samples around the psi(3770) mass region
(Iop Publishing, 2018)
To investigate the nature of the psi(3770) resonance and to measure the cross section for e(+)e(-) -> D (D) over bar, a cross-section scan data sample, distributed among 41 center-of-mass energy points from 3.73 to 3.89 ...
Measurement of the Branching Fraction For the Semileptonic Decay D0(+) -> pi(-(0))mu(+)nu(mu )and Test of Lepton Flavor Universality
(Amer Physical Soc., 2018)
Using a data sample corresponding to an integrated luminosity of 2.93 fb(-1) taken at a center-of-mass energy of 3.773 GeV with the BESIII detector operated at the BEPCII collider, we perform an analysis of the semileptonic ...
Measurements of absolute branching fractions for Lambda(+)(c) -> Xi K-0(+) and Xi(1530)K-0(+)
(Elsevier Science Bv., 2018)
We report the first measurements of absolute branching fractions for the W-exchange-only processes Lambda(+)(c) -> Xi K-0(+) and Lambda(+)(c)-> Xi(1530)K-0(+) with the double-tag technique, by analyzing an e(+)e(-) collision ...
Observation of a(0)(0)(980)-f(0)(980) Mixing
(Amer Physical Soc., 2018)
We report the first observation of a(0)(0)(980)-f(0)(980) mixing in the decays of J/psi -> phi f(0)(980) -> phi a(0)(0)(980) -> phi eta pi(0) and chi(c1) -> a(0)(0)(980)pi(0) -> f(0)(980)pi(0)->pi(+)pi(-)pi(0), using data ...
Study of electromagnetic Dalitz decays chi(cJ )-> mu(+)mu(-) J/psi

Using 4.48 x 10(8) psi(3686) events collected with the BESIII detector, we search for the decays chi(cJ) ->mu(+)mu(- )J/psi through the radiative decays psi(3686) -> gamma chi(cJ), where J = 0, 1, 2. The decays chi(c1,2) ...

Using a low-background sample of 2.6 x 10(5) J/psi -> omega eta(omega -> pi(+) pi(-) pi(0), eta -> gamma gamma) events, about 5 times larger statistics than previous experiments, we present a Dalitz plot analysis of the ...
