The energy spectra of light-mass kaonic nuclei were investigated using the theoretical framework $0s$-orbital model with zero-range $\bar{K} N$ and $\bar{K}\bar{K}$ interactions effective single-channel real potentials. energies NN$, NNN$, NNNN$, $\bar{K}\bar{K} N$, NN$ systems calculated in cases weak- deep-binding interaction, which was adjusted to fit $\Lambda(1405)$ mass bound state. result...

Three-body calculations of $K\bar{K}N$ system with quantum numbers $I=1/2$, $J^{\pi}=(\frac{1}{2})^{+}$ were performed. Using separable potentials for two-body interactions, we calculated the $\pi\Sigma$ mass spectra $(\bar{K}N)_{I=0}+K^{+}\rightarrow(\pi\Sigma)^{0}K^{+}$ reaction on basis three-body Alt-Grassberger-Sandhas equations in momentum representation. In this regard, different types $...

Understanding the properties of strange ${\mathrm{\ensuremath{\Lambda}}}^{*}$ baryon resonances is a long-standing and fascinating problem. ${\mathrm{\ensuremath{\Lambda}}}_{c}$ charm-baryon semileptonic weak decays to these are highly sensitive their internal structure can be used test theoretical models. We have performed first lattice-QCD computation form factors governing resonance: ${\math...

We study the unitarized meson-baryon scattering amplitude at leading order in strangeness $S=-1$ sector using time-ordered perturbation theory for a manifestly Lorentz-invariant formulation of chiral effective field theory. By solving coupled-channel integral equations with full off-shell dependence potential and applying subtractive renormalization, we analyze renormalized amplitudes obtain tw...

The photoproduction reaction of $\ensuremath{\gamma}p\ensuremath{\rightarrow}{K}^{+}\mathrm{\ensuremath{\Lambda}}(1405)$ is investigated based on an effective Lagrangian approach at the tree-level approximation with purpose understanding mechanism and extracting resonance contents associated parameters in this reaction. Apart from $t$-channel $K$ ${K}^{*}$ exchanges, $s$-channel nucleon ($N$) e...

The masses of the negative parity 70-plet baryons are analyzed in large N(c) QCD to order 1/N(c) and to first order in SU(3) symmetry breaking. The existing experimental data are well reproduced and 20 new observables are predicted. The leading order SU(6) spin-flavor symmetry breaking is small and, as it occurs in the quark model, the subleading in 1/N(c) hyperfine interaction is the dominant ...
