Effects on the hadron propagators due to terms in the vector meson propagator
H. X. Zhang, S. S. Wu
In an approximation where the baryon current conservation is violated, the contribution of the terms in the vector meson propagator may not vanish. Their effects on the ba…

Vector Meson Propagator and Baryon Current Conservation
S. S. Wu, H. X. Zhang, Y. J. Yao
If baryons couple only with -mesons, one found the baryon spectral function may be negative. We show this unacceptable result is caused by the -terms in the -meson pr…
