In a nutshell, could someone refresh my memory on supersymmetry and superparticles. I have trouble understanding these subjects of string theory.
Let's say we have a fermonic string of spin -1\2. What is it's superparticle's spin? Is it bosonic?

Thanks to all

The theory has strings with fermionic and bosonic degrees of freedom, that is all. No a elementary object being fermioni or bosonic.

What do you mean by degrees of freedom?

The chart available at the following link should be helpful regarding particles, superparticles, and spin:

Partner-superpartner spin relation?

According to this chart, the spin of a superpartner is always -1/2 the spin of the "ordinary" partner" except for the higgsino which is +1/2 the spin of the higgs.
I aways wondered why the photino couldn't have a spin of 3/2 instead of 1/2, for example.
Any references or explanations to explain why this is?

TIA

I seem to notice a buildup of papers like this: Detecting single gravitons with quantum sensing. (OK, old one.) Toward graviton detection via photon-graviton quantum state conversion Is this akin to “we’re soon gonna put string theory to the test”, or are these legit? Mind, I’m not expecting anyone to read the papers and explain them to me, but if one of you educated people already have an opinion I’d like to hear it. If not please ignore me. EDIT: I strongly suspect it’s bunk but...
