摘要
We demonstrate that the next to minimal supersymmetric model can have small fine-tuning and modest top-squark mass while still evading all experimental constraints. For small tan beta (large tan beta), the relevant scenarios are such that there is always (often) a standard-model-like Higgs boson that decays to two lighter-possibly much lighter-Higgs pseudoscalars.
