| contents | A study of light $Λ$ hypernuclei in chiral effective field theory is presented. For the first time chiral $Λ$NN and $Σ$NN three-body forces are included consistently. The calculations are performed within the no-core shell model. Results for the separation energies of the hypernuclei $^3_Λ\mathrm{H}$, $^4_Λ\mathrm{H}$/$^4_Λ\mathrm{He}$, $^5_Λ\mathrm{He}$, and $^7_Λ\mathrm{Li}$ are given. It is found that the experimental values can be fairly well reproduced once YNN three-body forces are taken into account. |
