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
(Amer Physic Soc., 2019)
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) ...
Precision Measurement of the e(+)e(-) -> Lambda(+)(c)(Lambda)over-bar(c)(-) Cross Section Near Threshold
(Amer Physical Soc., 2018)
The cross section of the e(+)e(-) -> Lambda(+)(c)(Lambda) over bar (-)(c) process is measured with unprecedented precision using data collected with the BESIII detector at root s = 4574.5, 4580.0, 4590.0 and 4599.5 MeV. ...
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 ...
Dalitz plot analysis of the decay omega -> pi(+) pi(-) pi(0)
(Amer Physical Soc., 2018)
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 ...
