Charm meson scattering cross sections by pion and rho meson

Using the local flavor SU(4) gauge invariance in the limit of vanishing vector meson masses, we extend our previous study of charm meson scattering cross sections by pion and rho meson, which is based only on the pseudoscalarpseudoscalar-vector meson couplings, to include also contributions from the couplings among three vector mesons and among four particles. We find that diagrams with light m...

Cross sections for meson-meson nonresonant reactions

Meson-meson nonresonant reactions governed by the quark-interchange mechanism are studied in a potential that is derived from QCD. S-wave elastic phase shifts for I = 2 ππ and I = 3/2 Kπ scattering are obtained with wave functions determined by the central spin-independent term of the potential. The reactions include inelastic scatterings of two mesons in the ground-state pseudoscalar octet and...

Meson Properties in Dense Hadronic Matter

One of the fundamental questions in strong interaction physics concerns the generation of mass in the sector of light quarks. How can nucleons with a mass of roughly 1 GeV arise from up and down quark masses of less than 10 MeV? The answer lies in the nonperturbative structure of the QCD vacuum itself in which quarks and gluons condense. This is in marked contrast to the heavy-quark sector wher...

Meson mass modification in strange hadronic matter

We investigate in stable strange hadronic matter (SHM) the modification of the masses of the scalar (σ, σ∗) and the vector (ω, φ) mesons. The baryon ground state is treated in the relativistic Hartree approximation in the nonlinear σ-ω and linear σ∗-φ model. In stable SHM, the masses of all the mesons reveal considerable reduction due to large vacuum polarization contribution from the hyperons ...

Meson Structure in Deep Inelastic Scattering

We study the deep inelastic structure functions of mesons within the Nambu and JonaLasinio model. We calculate the valence quark distributions in π, K, and ρ mesons at the low energy model scale, which are evoluted to the experimental momentum scale in terms of the Altarelli-Parisi equation. The resulting distribution functions show reasonable agreements with experiment. We also discuss the sem...
