Comment on the narrow charmonium state of Belle at 3871.8 MeV as a deuson
Nils A. Tornqvist
It is pointed out that the narrow charmonium state at 3871.8 MeV reported by the Belle collaboration is likely to be a deuteronlike meson-meson state called a deuson. I…
The light scalars, especially the sigma, in charm decay and elsewhere
N. A. Tornqvist, A. D. Polosa
We discuss how the lightest scalars, in particular the broad sigma resonance, can be understood as unitarized (qbar q) states within a unitarized quark model (UQM). The bare (qbar…
How to understand the lightest scalars
Nils A. Tornqvist
Based on previous papers I discuss how I understand the lightest scalars using a general coupled channel model. This model includes all light two-pseudoscalar thresholds, constrain…
Summary talk at the conference on the sigma resonance
Nils A. Tornqvist
This report summarizes the most important results presented at the recent conference held at the Yukawa Institute of Theoretical Physics in Kyoto, devoted to the recently confirmed…
The light scalars and the broad sigma(500) in the U3xU3 linear sigma model
Nils A. Tornqvist
The lightest scalar and pseudoscalar nonets are discussed within the [A framework of the broken old UxU3 linear sigma model, and it is shown that already at the tree level this mod…
Flavour symmetry as a Spontaneously Broken Discrete Permutation Symmetry Embedded in Colour
Nils A. Tornqvist
A new mechanism for breaking an internal symmetry spontaneously is discussed, which is intermediate between the Nambu-Goldstone and Wigner modes of symmetry breaking. Here the quar…
