Production of J / ψ p p ¯ in electron-positron collisions

Y. N. Song, Feng-Kun Guo

The discoveries of the hidden-charm P c pentaquarks by the LHCb Collaboration have been not confirmed by other experiments yet. It is desirable to investigate the feasibility of observing them in other experiments. We present an order-of-magnitude estimate of the cross section …

Decays of Υ ( 10860 ) and Υ ( 10753 ) into ω χ b J

Y. N. Song, Feng-Kun Guo

In this paper, we model Υ ( 10753 ) as a 4 S − 3 D bottomonium mixture and Υ ( 10860 ) as a 5 S − 4 D mixture, and predict the properties of a new bottomonium state, Υ ( …

Toward a precision determination of the X ( 6200 ) parameters from data

Y. N. Song, Yu Zhang, V. Baru, Feng-Kun Guo et autres

In a recent paper [], the LHCb data on the di- J / ψ production in proton-proton collisions were analyzed in a coupled-channel framework based on double-vector-charmonium channels. This investigation identified a robust pole near the J / ψ J / ψ …

Mass Measurement of Upper fp -Shell N=Z−2 and N=Z−1 Nuclei and the Importance of Three-Nucleon Force along the N=Z Line

M. Wang, Y. H. Zhang, Xianming Zhou, Xiao-Hong Zhou et autres

Using a novel method of isochronous mass spectrometry, the masses of $^{62}\mathrm{Ge}$, $^{64}\mathrm{As}$, $^{66}\mathrm{Se}$, and $^{70}\mathrm{Kr}$ are measured for the first time, and the masses of $^{58}\mathrm{Zn}$, $^{61}\mathrm{Ga}$, $^{63}\mathrm{Ge}$, $^{65}\mathrm{As}$, $^{67}\mathrm{Se}$, $^{71}\mathrm{Kr}$, and $^{75}\mathrm{Sr}$ are redetermined with improved accuracy. The new masses …

Mass measurements show slowdown of rapid proton capture process at waiting-point nucleus 64Ge

Xiao-Hong Zhou, M. Wang, Y. H. Zhang, Yu. A. Litvinov et autres

Abstract X-ray bursts are among the brightest stellar objects frequently observed in the sky by space-based telescopes. A type-I X-ray burst is understood as a violent thermonuclear explosion on the surface of a neutron star, accreting matter from a companion star in …

$$B\rho $$-defined isochronous mass spectrometry and mass measurements of $$^{58}$$Ni fragments

M. Zhang, Xianming Zhou, M. Wang, Y. H. Zhang et autres

Abstract A novel isochronous mass spectrometry, termed as $$B\rho $$ B ρ -defined IMS, has been established at the experimental cooler-storage ring CSRe in Lanzhou. Its potential has been studied through high precision mass measurements of $$^{58}$$ 58 Ni projectile fragments. Two …
