In elementary particle physics , sphermion ( eng. Sfermion ) is a hypothetical spin -0 particle- superpartner (or fortune ) of its associated fermion . Sphermions are bosons ( scalar bosons ), possess the same quantum numbers ^[4] . Can be the decay product of the Higgs boson ^[5] . They do not possess helicity , therefore, the left and right versions of the fermion have a separate sphermion ^[6] . Within the simplest models of supersymmetry, the masses of all sphermions are equal on the scale of supersymmetry breaking, and then diverge according to the renormalization group equations at lower energies ^[7] ^[8] In the supersymmetric extension of the Standard Model (CM), each particle has a spin superpartner that differs by ¹ ⁄ ₂ .
