Hadronic Molecules and the f0(980)/a0(980)
Tanja Branz, Thomas Gutsche, Valery E. Lyubovitskij
We discuss a possible interpretation of the f0(980) and a0(980) mesons as hadronic molecules - bound states of K and Kbar mesons. Using a phenomenological Lagrangian approach we ca…
Microscopic calculation of the decay of Jaffe-Wilczek tetraquarks, and the Z(4433)
Marco Cardoso, Pedro Bicudo
Here the tetraquarks are studied a la Jaffe and Wilczek. The decay width is fully computed with a microscopic quark model, using the resonating group method.
Searching for the Scalar Glueball
Wolfgang Ochs
Existence of gluonic resonances is among the early expectations of QCD. Today, QCD calculations predict the lightest glueball to be a scalar state with mass within a range of about…
New (and Old) Perspectives on Higgs Physics
John F. Gunion
Old and new ideas regarding Higgs physics are reviewed. We first summarize the quadratic divergence / hierarchy problem which strongly suggests that the SM Higgs sector will be sup…
How Universal is the Coupling in the Sigma Model?
Denis Parganlija, Francesco Giacosa, Dirk H. Rischke
We calculate pion-pion scattering lengths and sigma, rho and a1 decay widths from a gauged linear sigma model with two flavours and its globally invariant generalisation.
Dynamical Properties of the Meson
H. Q. Zheng
Studies on the dynamical properties of the meson are reviewed and discussed. The important role of fundamental principles such as analyticity, unitarity and crossing symmetry p…
