By using effective chiral Lagrangians with a suitable incorporation of the scaling property QCD, we establish approximate in-medium law, ${\mathit{m}}_{\mathrm{\ensuremath{\sigma}}}^{\mathrm{*}}$/${\mathit{m}}_{\mathrm{\ensuremath{\sigma}}}$\ensuremath{\approxeq}${\mathit{m}}_{\mathrm{N}}^{\mathrm{*}}$/${\mathit{m}}_{\mathrm{N}}$...
We propose that the quenching of Gamow-Teller matrix elements in light nuclei can be effectively described by a mechanism governs $p$-wave pion-nucleus scattering. This may providing solution to long-standing problem. The resulting Landau-Migdal parameter ${g}^{\ensuremath{'}}$ turns out quite consistent with values extracted from spectra pionlike excitations and places stringent constraint on pion condensation nuclear matter.
It is shown that the time component of axial currents in nuclei can be given a simple description terms one-pion exchange diagram with its structure constrained by soft-pion theorem. We suggest directional correlation measurements nuclear $\ensuremath{\beta}$ decay as possible means to test theory.
Furnishing Skyrme's chiral soliton with a quark-bag core appears to generate qualitative advance in the phenomenology of nucleon structure.Received 31 May 1983DOI:https://doi.org/10.1103/PhysRevLett.51.747©1983 American Physical Society
Topologically stable solitonic solutions to Skyrme's chiral-invariant Lagrangian have been obtained numerically. The single parameter in these has determined with the Goldberger-Treiman relation. identification of objects baryons leads sensible statements regarding sizes and energies as well two- three-body interactions between at zero separation.
Spurred by the recent complete determination of weak currents in two-nucleon systems up to $\mathcal{O}{(Q}^{3})$ heavy-baryon chiral perturbation theory, we carry out a parameter-free calculation threshold S factors for solar $\mathrm{pp}$ (proton-fusion) and hep processes an effective field theory (EFT) that combines merits standard nuclear physics method systematic expansion. The power EFT adopted here is one can correlate unified formalism weak-current matrix elements two-, three-,...
We study baryons in a holographic model of QCD by Sakai and Sugimoto, realized as small instantons with fundamental string hairs. introduce an effective field theory the five-dimensional setting, show that instanton interpretation implies particular magnetic coupling. Dimensional reduction to four dimensions reproduces usual chiral action, and, particular, we estimate axial coupling ${g}_{A}$ between pions dipole moments, both which are proportional ${N}_{c}$. extrapolate finite ${N}_{c}$...
We derive an effective action combining chiral and heavy-quark symmetry, using approximate bosonization techniques to QCD-inspired models of spontaneous symmetry breaking. explicitly show that the limit is compatible with large ${N}_{c}$ (number color) in meson sector, estimate couplings between light heavy mesons ($D, {D}^{*}, \dots{}$) their partners order one mass. The relevance this solitons quarks briefly discussed.
In a previous article, the four-dimensional (4D) half-Skyrmion (or five-dimensional dyonic salt) structure of dense baryonic matter described in crystalline configuration large ${N}_{c}$ limit was shown to have nontrivial consequences on how antikaons behave compressed nuclear with possible implication for ``ice-9'' phenomenon deeply bound kaonic and condensed kaons compact stars. We extend analysis make further prediction scaling properties hadrons that surprising effect tensor forces,...
