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 ...

Bidirectional Hybrid DC Circuit Breaker With Zero Voltage and Current Switching for Radar Power System

IEEE Open Journal of Industry Applications
This article proposes a novel zero-voltage switching (ZVS) and zero-current switching (ZCS)-based hybrid dc circuit breaker for a radar power system. Long-range radars demand huge power, in the order of hundreds of kW. Radar's phased array antenna

RH -ZCs

This work presents ZCS–RH, a Zero-Centric System framework offering a structural and conceptual perspective related to the Riemann Hypothesis. The approach treats zero as an organizing element in numerical and positional systems, exploring digit-space behavior, numerical transitions, and structural patterns relevant to prime distribution.

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)±π∓→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 ...

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
