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 ...
Future Physics Programme of BESIII
(IOP Publishing, 2020)
There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics. This renaissance has been driven in part by the discovery of a plethora of charmonium-like XYZ states at BESIII and B factories, ...
Measurements of e(+) e(-) -> eta(c)pi(+)pi(-)pi(0), eta(c)pi(+)pi(-), and eta(c)pi(0)gamma at root s from 4.18 to 4.60 GeV, and search for a Z(c) state close to the D(D)over-bar threshold decaying to eta(c)pi at root s=4.23 GeV
(Amer Physical Soc., 2021)
We study eta(c) production at center-of-mass energies root s from 4.18 to 4.60 GeV in e(+)e(-) annihilation data collected with the BESIII detector operating at the BEPCII storage ring, corresponding to 7.3 fb(-1) of ...
Search for the X (2370) and observation of eta(c) -> eta eta eta ' in J/psi -> gamma eta eta eta '
(Amer Physical Soc., 2021)
Using a sample of 1.31 x 10(9) J/psi events collected with the BESIII detector, we perform a study of J/psi -> gamma eta eta eta' to search for the X(2370) and eta(c) in the eta eta eta' invariant mass distribution. No ...
Study of the decays D+-> eta(('))e(+)nu(e)
(Amer Physic Soc., 2018-05-31)
The charm semileptonic decays D+ -> eta e(+)nu(e) and D+ -> eta'e(+)nu(e) are studied with a sample of e(+)e(-) collision data corresponding to an integrated luminosity of 2.93 fb(-1) collected at root s = 3.773 GeV with ...
Sigma(+) and (Sigma)over-bar(-) Polarization in the J/psi and psi(3686) Decays
(Amer Physical Soc., 2020)
From 1310.6 x 10(6) J/psi and 448.1 x 10(6) psi (3686) events collected with the BESIII experiment, we report the first observation of Sigma(+) and (Sigma) over bar (-) spin polarization in e(+)e(-) -> J/psi[psi(3686)] -> ...
Measurement of J/psi -> Xi(1530+)(-) (Xi)over-bar(+) and evidence for the radiative decay Xi(153)(-) -> gamma Xi(-)
(Amer Physical Soc., 2020)
The SU(3)-flavor violating decay J/psi -> Xi(1530)(-) (Xi) over bar (+) + c.c. is studied using (1310.6 +/- 7.0) x 10(6) J/psi events collected with the BESIII detector at BEPCII, and the branching fraction is measured to ...
Search for the decay J/psi -> gamma plus invisible
(Amer Physical Soc., 2020)
We search for J/psi radiative decays into a weakly interacting neutral particle, namely an invisible particle, using the J/psi produced through the process psi(3686) -> pi(+)pi(-) J/psi in a data sample of (448.1 +/- 2.9) ...
Women in Politics and Child Labor: an Instrumental Variable Approach
(Palgrave Macmillan, 2020)
This paper examines the impact of the empowerment of women in politics on child labor. The literature both on women in politics and on child labor lacks empirical evidence on the presence of the causality running from ...
Frequency, voltage and illumination interaction with the electrical characteristics of the CdZnO interlayered Schottky structure
(Springer, 2019)
cadmium-zincoxide (CdZnO) interlayered metal-semiconductor structure was examined by capacitance and conductance versus voltage data in dark and under 250W illumination at 100kHz, 500kHz and 1MHz frequencies, respectively. ...
