    "abstract": "We calculate the leading contribution to the weak $\\Lambda \\Lambda K$\ncoupling in heavy baryon chiral perturbation theory, including the SU(3)\nbreaking terms arising at one-loop. This coupling gives the leading one-boson\nexchange amplitude for the process $\\Lambda\\Lambda\\to\\Lambda n$ and is an\nimportant component in understanding the decay of $\\Lambda\\Lambda$-hypernuclei.\nWe find the S-wave and P-wave amplitudes to be stable under one-loop\ncorrections, but the associated errors become large. We discuss the theoretical\nerrors and potential effects of higher order terms.",
