Master Formulae Approach to Photon Fusion Reactions
C. -H. Lee, H. Yamagishi, I. Zahed
We analyze the reactions through GeV, using the master formula approach to QCD with three flavors. In this approach, the constraints of broken c…
Dilepton and Photon Emission Rates from a Hadronic Gas III
C. -H. Lee, H. Yamagishi, I. Zahed
We extend our early analyses of the dilepton and photon emission rates from a hadronic gas to account for strange mesons using a density expansion. The emission rates are reduced t…
Two Topics in Chiral Effective Lagrangians
Hidenaga Yamagishi, Ismail Zahed
In the absence of nucleons, we use partial wave unitarity, to show that the chiral expansion parameter must be close to rather than as previously su…
Electromagnetic Emission Rates and Spectral Sum Rules
James Steele, Hidenaga Yamagishi, Ismail Zahed
The electromagnetic emission rates at SPS energies satisfy spectral constraints in leading order in the pion and nucleon densities. These constraints follow from the strictures of…
Is Quantization of QCD Unique at the Non-Perturbative Level ?
Hidenaga Yamagishi, Ismail Zahed
We find that QCD in covariant gauge yields zero for the topological susceptibility, even at the nonperturbative level. The result is derived in two ways, one using translational in…
On-Shell Approach to Pion-Nucleon Physics
James V. Steele, Hidenaga Yamagishi, Ismail Zahed
We discuss an on-shell approach to pion-nucleon physics that is consistent order by order in a expansion with the chiral reduction formula, crossing, and relativistic unita…
