Radiative Decays involving a0(980) and f0(980) in the Vector Meson Dominance Model
Deirdre Black, Masayasu Harada, Joseph Schechter
We summarize some features of the vector meson dominance model which was recently proposed for studying radiative decays involving the scalar mesons. Using the experimental values…
Study of Scalar Mesons and Related Radiative Decays
D. Black, M. Harada, J. Schechter
After a brief review of the puzzling light scalar meson sector of QCD, a brief summary will be given of a paper concerning radiative decays involving the light scalars. There, a si…
Introduction to effective Lagrangians for QCD
Joseph Schechter
A brief introduction to the effective Lagrangian treatment of QCD (in the sense of using fields representing physical particles rather than quarks and gluons) will be given. The hi…
Exploring the structure of a possible light scalar nonet
Deirdre Black, Amir H. Fariborz, Joseph Schechter
We first review the work of the Syracuse group, which uses an effective chiral Lagrangian approach, on meson-meson scattering. An illustration providing evidence for the existence…
The Skyrme Model for Baryons
J. Schechter, H. Weigel
We review the Skyrme model approach which treats baryons as solitons of an effective meson theory. We start out with a historical introduction and a concise discussion of the origi…
Symmetry Breaking in a Generalized Skyrme Model
J. Schechter
We first outline the calculations of the neutron-proton mass difference and of the axial singlet matrix element (relevant to the "proton spin" puzzle) in a generalized Skyrme model…
