The Faddeev equations for the $\Xi NN$ bound-state problem are solved where three $S$=$-2$ baryon-baryon interactions of J\"ulich-Bonn-M\"unchen chiral EFT, HAL QCD and Nijmegen ESC08c used. $T$-matrix $T_{\Xi N, \Xi N}$ obtained within original $\Lambda\Lambda$-$\Xi N$-$\Sigma\Sigma$ $/$ N$-$\Lambda \Sigma$-$\Sigma\Sigma$ coupled-channel framework is employed as an input to equations. We found...
A search for invisible decays of the $\Lambda$ baryon is carried out in process $J/\psi\to\Lambda\bar{\Lambda}$ based on $(1.0087\pm0.0044)\times10^{10}$ $J/\psi$ events collected with BESIII detector located at BEPCII storage ring. No signals are found baryon, and upper limit branching fraction determined to be $7.4 \times 10^{-5}$ 90% confidence level. This first baryons; such searches will p...
A modular representation for the semileptonic decays of baryons originating from spin polarized and correlated baryon-antibaryon pairs is derived. The complete information decaying baryon propagated to daughter via a real-valued matrix. It allows obtain joint differential distributions in sequential processes involving decay straightforward way. formalism suitable extraction formfactors experim...
The momentum correlation functions of S = -2 baryon pairs (p Xi^- and Lambda Lambda) produced in high-energy pp pA collisions are investigated on the basis coupled-channel formalism. strong interaction is described by HAL QCD potential obtained lattice simulations near physical quark masses, while hadronic source function taken to be a static Gaussian form. effect, threshold difference, realist...

Abstract We present a study on inclusive emissions of double $$\Lambda _c$$ Λ c or plus light-flavored jet system as probe channels in the semi-hard regime QCD. Our formalism relies so-called hybrid high-energy/collinear factorization, where standard collinear descripti...
We present the first lattice-QCD calculation of form factors governing charm-baryon semileptonic decays $\Lambda_c \to \Lambda^*(1520)\ell^+\nu_\ell$. As in our previous $\Lambda_b \Lambda^*(1520)$ factors, we work $\Lambda^*(1520)$ rest frame, but here use four different heavy-baryon momenta instead just two. Because lower mass $\Lambda_c$, moderately-sized used are sufficient to determine ful...
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...
The LHCb collaboration has detected a new hidden-charm pentaquark with the quantum numbers of $\mathrm{\ensuremath{\Lambda}}$ baryon: ${P}_{\ensuremath{\psi}s}^{\mathrm{\ensuremath{\Lambda}}}(4338)$. This will be interpreted as ${\overline{D}}_{s}{\mathrm{\ensuremath{\Lambda}}}_{c}\ensuremath{-}\overline{D}{\mathrm{\ensuremath{\Xi}}}_{c}$ resonance within contact-range theory. Here we briefly c...
