Can you give me an intuitive understanding of the following:(adsbygoogle = window.adsbygoogle || []).push({});

"The spin states of massive and massless Majorana spinors transform in representations of SO(D-1) and SO(D-2), respectively".

I see the similarity with vectors bosons, where massive vectors have d-1 degrees of freedom and massless have d-2, but what exactly is meant by "the spin states of (...) Majorana spinors transform"?
