The order mesonic chiral Lagrangian
Johan Bijnens, Nils Hermansson-Truedsson, Si Wang
We derive the chiral Lagrangian at next-to-next-to-next-to-leading order (NNNLO) for a general number of light quark flavours as well as for . We enumerate the conta…
Pion Helicity Structure And Its Consequence For The Hard Scattering Form Factor
Siwen Wang, Leonard S. Kisslinger
In a study of the elastic pion form factor for large momentum transfers based on a modified perturbative QCD (PQCD) approach we have included helicity components that are customari…
Meson-Baryon-Baryon Vertex Function and the Ward-Takahashi Identity
Siwen Wang, Manoj K. Banerjee
Ohta proposed a solution for the well-known difficulty of satisfying the Ward-Takahashi identity for a photo-meson-baryon-baryon amplitude (MBB) when a dressed meson-baryon-bary…
Pion Form Factor: Transition From Soft To Hard QCD
Leonard S. Kisslinger, Siwen Wang
We have reexamined the elastic pion form factor over a broad range of momentum transfers with the mass evolution from current quark to constituent quark being taken into account. W…
