Search for the reaction e(+) e(-) -> chi(cJ)pi(+)pi(-) and a Charmoniumlike Structure Decaying to chi(cJ)pi(+/-) between 4.18 and 4.60 GeV
(Amer Physical Soc., 2021)
We search for the process e(+)e(-) -> chi(cJ)pi(+) pi(-) (J = 0, 1, 2) and for a charged charmoniumlike state in the chi(cJ)pi +/- subsystem. The search uses datasets collected with the BESIII detector at the BEPCII storage ...
On a New Approach by Modified (P; Q)-Szasz-Mirakyan Operators
(Etamaths Publ., 2021)
In this paper, we introduce a new type of (p; q) exponential function with some properties and a modified (p; q)-Szasz-Mirakyan operators by virtue of this function by investigating approximation properties. We obtain ...
Measurement of the Born cross sections for e(+)e(-) -> D-s(+) D-s1 (2460)(-) +c.c. and e(+) e(-) -> D-s*(+) D-s1 (2460)(-)( )+ c.c.
(Amer Physical Soc., 2020)
The processes e(+)e(-) -> D-s(+) D-s1 (2460)(-) + c.c. and e(+) e(-) -> D-s*(+) D-s1 (2460)(-)+ c.c. are studied for the first time using data samples collected with the BESIII detector at the BEPCII collider. The Born ...
Measurement of the Branching Fraction for psi (3686) ->omega(KSKS0Y)-K-0
(Amer Physical Soc., 2021)
Analyzing (448.1 +/- 2.9) x 10(6) psi (3686) events collected with the BESIII detector at the BEPCII collider, the psi(3686) -> omega(KSKS0)-K-0 decay is observed for the first time. The branching fraction for this decay ...

Observation of D+ -> eta eta pi(+) and improved measurement of D0(+) -> eta pi+ pi-((0))
(Amer Physical Soc., 2020)
Using an e(+)e(-) annihilation data sample corresponding to an integrated luminosity of 2.93 fb(-1) collected at the center-of-mass energy of 3.773 GeV with the BESIII detector, we measure the absolute branching fractions ...
Observation of a Resonant Structure in e(+)e(-) -> K+ K- pi(0)pi(0)
(Amer Physical Soc., 2020)
A partial-wave analysis is performed for the process e(+)e(-) -> K+ K- pi(0)pi(0) at the center-of-mass energies ranging from 2.000 to 2.644 GeV. The data samples of e(+)e(-) collisions, collected by the BESIII detector ...

(Amer Physical Soc., 2020)
By analyzing a data sample corresponding to an integrated luminosity of 2.93 fb(-1) collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we measure for the first time the absolute branching fraction ...
Amplitude Analysis and Branching-fraction Measurement of D-s(+) -> (KSK-)-K-0 pi(+)pi(+)
(Amer Physical Soc., 2021)
Using 6.32 fb(-1) of e(+)e(-) collision data collected by the BESIII detector at the center-of-mass energies between 4.178 and 4.226 GeV, an amplitude analysis of the D-s(+) -> (KSK-)-K-0 pi(+)pi(+) decays is performed for ...
First measurements of chi(cJ) -> Sigma(-)(Sigma)over-bar(+) (J=0,1,2) decays
(Amer Physical Soc., 2020)
We measured the branching fractions of the decays chi(cJ) -> Sigma(-)(Sigma) over bar (+) for the first time using the final states n (n) over bar pi(+)pi(-). The data sample exploited here is 448.1 x 10(6) psi(3686) events ...
