Heavy baryon chiral perturbation theory (HBChPT) is an effective quantum field theory used to describe the interactions of pions and nucleons/baryons. It is somewhat an extension of chiral perturbation theory which just describes the low-energy interactions of jydrescueteam.com a richer theory one would also like to describe the interactions of baryons with pions.

We study the KNΣ and KNΛ coupling constants using QCD sum rules. We consider the correlators of two interpolating baryon fields taken with kaon in initial state.

The parts of the correlators with Dirac structure k / γ 5 are used, keeping all terms up to dimension 5 in the OPE and including continuum contributions on the phenomenological side. The ratios of these sum rules to baryon mass sum Cited by: 2.

SC-LQCD Based Approach to Baryon Mass. Recently, a new form of dark matter has been suggested to naturally reproduce the empirically successful aspects of Milgrom's law in Baryon coupling regularities book.

The dark matter particle candidates are axion-like, with masses of order eV and strong self-interactions. They Bose-Einstein condense into a superfluid phase in the central regions of galaxy halos. The superfluid phonon excitations in turn couple to Cited by: In this regime one should use some non-perturbative methods.

Among other approaches, the QCD Sum Rules (QCDSR) method has proven Baryon coupling regularities book be a powerful tool to extract qualitative and quantitative information about hadron properties.

Our aim in this work is to calculate the meson-baryon coupling constants using the method of jydrescueteam.com: Güray Erkol. Abstract.

The original results for the baryon-pion couplings in the large \(N_c\) QCD can be understood in a simpler way in the Hartree-Fock picture. The large \(N_c\) relation and its \(1/N_c\) correction between the heavy baryon-meson coupling and the light baryon-meson coupling are emphasized.

Application to the baryon-\(\rho\) meson interactions is jydrescueteam.com: Chun Liu. Dec 01,  · Within the framework of the non-relativistic quark model (NRQM) we discuss the influence of the coupling between baryonic excitations and meson fields.

Photon-Baryon Fluid Before recombination, Thomson scattering between the photons and electrons and coulomb interactions between the electrons and baryons were sufficiently rapid that the photon-baryon system behaves as a single tightly coupled fluid.

Formally, one expands the evolution equations in powers of the Thomson mean free path over the. We evaluate the pseudoscalar-meson coupling constants and the strangeness-conserving and the strangeness-changing axial charges of octet baryons in lattice QCD with two flavors of dynamical quarks.

We find that the coupling constants and the axial charges have rather weak quark-mass dependence and the breaking in SU(3)-flavor symmetry is small at each quark-mass point we jydrescueteam.com: Güray Erkol, Makoto Oka, Toru T.
