Beta-delated proton emission with Halo Effective Field Theory*

Halo nuclei offer an interesting way to study beta-decay in nuclear systems. For example, recently experiments measured a surprisingly large branching ratio for beta-delayed proton emission in 11Be. A resonance that can enhance the rate for this process has also been reported. In halo effective field theory, halo nuclei like 11Be can be described in a systematic low-energy expansion facilitated by the separation of scales between halo matter radius and core radius. I will describe our recent calculation of beta-delated proton emission within this framework and how it relates to recent experimental results.
