Description

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
puzzle in neutron stars; and (iv) Onset of binding in double-Lambda
hypernuclei [4].
