Virtual Compton Scattering and Generalized Polarizabilities of the Nucleon in Heavy Baryon Chiral Perturbation Theory
Virtual Compton scattering amplitude of nuclear chiral perturbation theory the tree level amplitude
2014/12/23
The spin-independent part of the virtual Compton scattering (VCS) amplitude from the nucleon is calculated within the framework of heavy baryon chiral perturbation theory (HBChPT). The calculation is ...
Improving the Convergence of SU(3) Baryon Chiral Perturbation Theory
Baryon chiral perturbation theory the chiral expansion momentum space physics
2014/12/23
Baryon chiral perturbation theory as conventionally applied using dimensional regularization has a well-known problem with the convergence of the SU(3) chiral expansion. One can reformulate the theory...
Systematic 1/M expansion for spin 3/2 particles in baryon chiral perturbation theory
The theory of relativity pion - nucleon - delta system spin 3/2 resonance nuclear soft power the quality of meson
2014/12/22
Starting from a relativistic formulation of the pion-nucleon-delta system, the most general structure of 1/M corrections for a heavy baryon chiral lagrangian including spin 3/2 resonances is given. Th...
Heavy baryon chiral perturbation theory with light deltas
Chiral perturbation theory the meson scale expansion
2014/12/22
We demonstrate how heavy mass methods, previously applied to chiral perturbation theory calculations involving the interactions of nucleons and pions, can be generalized to include interactions with t...
Improved treatment of loop diagrams in SU(3) baryon chiral perturbation theory
Baryon chiral perturbation theory the chiral expansion cycle graph the amount of space
2014/12/22
Baryon chiral perturbation theory as conventionally applied has a well-known problem with the SU(3) chiral expansion in that loop diagrams generate very large SU(3) breaking corrections and greatly up...
SU(3) baryon chiral perturbation theory and long distance regularization
Chiral perturbation theory the low energy goldstein boson
2014/12/22
The use of SU(3) chiral perturbation theory in the analysis of low energy meson-baryon interactions is discussed. It is emphasized that short distance effects, arising from propagation of Goldstone bo...
Light baryon magnetic moments and N ->Delta gamma transition in a Lorentz covariant chiral quark approach
Magnetic moment light baryons lorentz covariance baryons bound state pseudo-scalar meson
2014/12/20
We calculate magnetic moments of light baryons and N→Δγ transition characteristics using a manifestly Lorentz covariant chiral quark approach for the study of baryons as bound states of constituent qu...
Semileptonic decays of the light J(P)=1/2(+) ground state baryon octet
Lorentz covariance quark model factoring factors the parameters of the quality
2014/12/19
We calculate the semileptonic baryon octet-octet transition form factors using a manifestly Lorentz covariant quark model approach based on the factorization of the contribution of valence quarks and ...
