I'm currently doing a third year project (undergraduate) on supersymmetry, and am slightly confused as to just how the Higgs naturalness problem is solved through adding superparticles to the standard model. I've been advised to include discussion of radiative corrections, which, at most, all i know is they cancel out something which would otherwise send the Higgs mass to infinity. I would like to understand these corrections in greater detail, and be able to explain just how and why this solves the problem. Any help, or even some good links (ive exhausted wikipedia) aimed at people who arent already experts in this field would be greatly appreciated!!
