Light Scalar Mesons as Manifestation of Spontaneously Broken Chiral Symmetry
Light Scalar Mesons Spontaneously Broken Chiral Symmetry
2010/3/15
Attention is paid to the production mechanisms of light scalars that reveal their nature. We reveal the chiral shielding of the \sigma(600) meson. We show that the kaon loop mechanism of the \phi radi...
Three-body force and the tetraquark interpretation of light scalar mesons
scalar meson tetraquark three-body force
2009/8/14
We study the possible tetraquark interpretation of light scalar meson states a0(980), f0(980), κ,σ within the framework of the non-relativistic potential model. The wave functions of tetraquark states...
