Precison Measurements of the Mass, the Widths of $ψ (3770)$ Resonance and the Cross Section $σ [e^{+} e^{-} \to ψ (3770)]$ at $E_{cm} = 3.7724$ GeV

M. Ablikim et al.

By analyzing the $R$ values measured at 68 energy points in the energy region between 3.650 and 3.872 GeV reported in our previous paper, we have precisely measured the mass, the t…

Is the $σ$ meson dynamically generated?

Zhi-hui Guo, L. Y. Xiao, H. Q. Zheng

We study the problem whether the $σ$ meson is generated `dynamically'. A pedagogical analysis on the toy O(N) linear sigma model is performed and we find that the large $N_{c}$ limit…

Lightest scalars as chiral partners of the Nambu--Goldstone bosons

L. Y. Xiao, H. Q. Zheng, Z. Y. Zhou

We review the spectrum of lightest scalar resonances recently determined using dispersion techniques. The conceptual difference between the pole mass and the bare mass (or the line…

Measurements of the cross sections for $e^{+} e^{-} \to hadrons$ at 3.650, 3.6648, 3.773 GeV and the branching fraction for $ψ (3770) \to non - D D ˉ$

M. Ablikim et al.

Using the BES-II detector at the BEPC Collider, we measured the lowest order cross sections and the $R$ values ( $R = σ_{e^{+} e^{-} \to hadrons}^{0} / σ_{e^{+} e^{-} \to μ^{+} μ^{-}}^{0}$ ) for incl…

An improved study of the kappa resonance and the non-exotic $s$ wave $π K$ scatterings up to $s = 2.1$ GeV of LASS data

Z. Y. Zhou, H. Q. Zheng

We point out that the dispersion relation for the left hand cut integral presented in one of our previous paper (Nucl. Phys. {\bf A}733(2004)235) is actually free of subtraction co…
