Description

We investigate the leading-twist transverse-momentum-dependent distribution functions (TMDs) for the $\Lambda^0$ and the $\Lambda_c$ heavy baryon, a spin-1/2 composite system consisting of two light quarks ($u$ and $d$) and a heavy quark s/c, using the basis light-front quantization (BLFQ) framework. The light-front wave functions of the heavy baryon in the leading Fock sector are obtained from the eigenfunctions of the light front Schrodinger equation $\hat{H}_{\rm eff}|\Psi\rangle=M^2|\Psi\rangle$, where $\hat{H}_{\rm eff}$ is the effective Hamiltonian of the system. We evaluate the TMDs using the overlaps of the light-front wave functions. We also study the spin-densities in momentum space of quarks inside the $\Lambda^0$ and the $\Lambda_c$ baryons for various combinations of their polarizations.
