A novel single-phase ZCS-PWM high power factor boost rectifier

, 1997
This paper presents a novel single-phase high power factor PWM boost rectifier, featuring soft commutation of the active switches at zero-current (ZCS). It incorporates the most desirable properties of the conventional PWM and the soft-switching resonant

Production of $$Z_c(3900$$ Zc(3900 ) and $$Z_c(4020)$$ Zc(4020) in $$B_c$$ Bc decay

European Physical Journal C: Particles and Fields, 2019
Abstract In the present work, we propose to search the charmonium-like states $$Z_c(3900$$ Zc(3900 ) and $$Z_c(4020)$$ Zc(4020) in the $$B_c$$ Bc decay. In an effective Lagrangian approach, the branching ratios of $$B_c^+ \rightarrow Z_c(3900)^+ \pi ^0$$ Bc+→Zc(3900)+π0 and $$B_c^+\rightarrow Z_c (4020)^+ \pi ^0$$ Bc+→Zc(4020)+π0 are estimated to be of

Search for Zc (3900)± →ωπ± SEARCH for Zc (3900)± →ωπ± M. ABLIKIM et al

, 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)±πl→ωπ+π- are determined ...

Zc(3900)/Zc(3885) as a virtual state from πJ/ψ-D¯∗D interaction

European Physical Journal C, 2018
In this work, we study the πJ/ψ and D¯∗D invariant mass spectra of the Y (4260) decay to find out the origin of the Zc(3900) and Zc(3885) structures. The πJ/ψ-D¯∗D interaction is studied in a coupled-channel quasipotential Bethe–Saltpeter equation approach, and embedded to the Y (4260) decay process to reproduce both π-J/ψ and D∗-D0 invariant mass ...
