In summary, the conversation discusses the concept of supersymmetric partners and their expected pairing with fundamental particles of the Standard Model. It also mentions the unofficial name "Higgsino" for the supersymmetric partner to the Higgs boson and the claim that it should be less massive than the Higgs boson. However, specific references are needed to support these claims. It is also noted that a pop science book is not a valid source for discussion on this topic.

TL;DR Summary
SUSY supersymmetry Higgsino
Supersymmetric partners are expected to only pair off with "fundamental" particles of the Standard Model. (photon, W, Z, gluons, leptons, quarks, graviton). In all those canonical particles, the SUSY partner is significantly more massive than its counterpart.

Internet sources suggest that unofficial name of the supersymmetric partner to the Higgs is the "Higgsino". Unlike the rest of the particle pantheon, the Higgsino should be significantly less massive than the Higgs boson. Does this low mass mean we should have already found the Higgsino in experiments?

Any other notes we should know about the Higgsino?

Hey why look at those stuffy old peer-reviewed papers when you have a couple of guys on the internet?

I think you just made this up. You didn't give a source, and if you did get it from elsewhere, they don't know what they are talking about.
  1. In SUSY, the SM Higgs sector has at least five particles.
  2. There are therefore five SUSY partners.
  3. These particles mix with gauginos, so in general there is no particle that is a pure "higgsino".
  4. Obviously then a statement about mass is meaningless.

Please give specific references for these claims; "Internet sources" is not enough.

Roger Penrose has claimed that spin-0 particles would in all cases be more massive than their superpartners. This would also include the Higgs being more massive than its superpartner, the Higgsino, ( as the Higgs is spin-0. ) He seems to imply that this follows from the non-existence of negative spin.

This claim appears on page 875, chapter 31, section 2 of the following book.

This is a pop science book, not a textbook or peer-reviewed paper. As such, it is not a valid source for PF discussion.
