Progress on several persistent problems in single- and double-Lambda light

hypernuclei is briefly reviewed in this talk: (i) Lifetimes of the weakly

bound Lambda-3H (Lambda-p-n), and of Lambda-3n (Lambda-n-n) if existing [1];

(ii) Charge Symmetry Breaking in the A=4, isospin I=1/2, Lambda hypernuclei

[2]; (iii) Overbinding of Lambda-5He [3], apparently related to the hyperon

The attractive nature of $\bar{K}N$ interaction has stimulated theoretical and experimental searches for $K^-$ bound states in different systems. In particular, many theoretical calculations devoted to the lightest possible system $\bar{K}NN$ have been performed using different methods: Faddeev equations with coupled channels, variational methods, and some others. All of them agree that a...

Investigating few-body systems with identical particles in a hyperspherical basis yields the problem of obtaining symmetrized hyperspherical functions from functions with arbitrary quantum numbers. This article solves the problem of hyperspherical basis symmetrization for four-,five- ,and six- body systems using Parentage Scheme of Symmetrization. Parentage coefficients corresponding to the...

Inspired from AdS/QCD light-front wave functions, we calculate the generalized parton distributions (GPDs) of pion. The impact-parameter dependent parton distribution functions (ipdpdf) and the GPDs in longitudinal boost-invariant space are also obtained by taking the Fourier transforms. We also calculate the charge density, gravitational form factor and the unpolarized transverse momentum...
