Axialvector tetraquark candidates for Zc(3900), Zc(4020), Zc(4430), and Zc(4600) Supported by National Natural Science Foundation (11775079)

Chinese Physics, 2020
We construct the axialvector and tensor current operators to systematically investigate the ground and first radially excited tetraquark states with quantum numbers using the QCD sum rules. We observe one axialvector tetraquark candidate for and , two axialvector tetraquark candidates for the , and three axialvector tetraquark candidates for .

Study on decays of Zc(4020) and Zc(3900) into hc+π

European Physical Journal C, 2016
At the invariant mass spectrum of hcπ± a new resonance Zc(4020) has been observed, however, the previously confirmed Zc(3900) does not show up at this channel. In this paper we assume that Zc(3900) and Zc(4020) are molecular states of DD¯∗(D∗D¯) and D∗D¯∗ , respectively, then we calculate the transition rates of Zc(3900)→hc+π and Zc(4020)→hc+π in the ...

Behavioral model for emulation of ZC-CG-VDCC

IEICE Electronics Express, 2016
This paper presents a proposal and an experimental analysis of behavioral emulator of so-called z-copy controlled-gain voltage differencing current conveyor (ZC-CG-VDCC) based on commercially available devices. Most of them are electronically (by DC voltage) controllable. This work represents a suitable example of preliminary stage of development of an

Search for Zc (3900))± → ωπ±

, 2015
The decay Zc(3900)±→ωπ± is searched for using data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of-mass energies s√=4.23 and 4.26 GeV. No significant signal for the Zc(3900)± is found, and upper limits at the 90% confidence level on the Born cross section for the process e+e−→Zc(3900)±π∓→ωπ+π− are determined
