Black matter, you mean dark matter, right?

What are your own investigations regarding this?

You have tagged the thread "A" which means you want replies on a phd/graduate level, are you aware of that? Or do you want us to reply in a "B" i.e. more like popular science level? Let me/us know and we get back you with a reply on an approriate level.

Cheers

You mean Black Lives Matter?

No politics on this forum.

Yes. I am Portuguese where the translation of “dark matter” is sometimes not well done.
thank you by the alert

I am a retired chemical engineer so “A” is not correct. How can I change it?

How do YOU think they are related? What do you understand each of them to be?

I think it is unknown how dark matter particles interact with the Higgs Boson, if their mass is due to the higgs boson or some other mechanism. Btw most of the mass of the baryonic matter is mostly due to a phenomenon named "Color Confinement" of the quantum chromodynamics and not due to the higgs boson.

.Here's a discussion on it from the American Physical Society circa 2017:

Connection to gravity: several gravitational phemomena such as rotation speeds of galaxies, speeds of galaxies in galaxy clusters, gravitational lensing of single galaxies - are not explainable using calculations of such phenomena with Newtonian gravity and general relativity. The reason for this is either that there is more matter than what is visible (interact via electromagnetism) or that we simply do not understand gravity, or have missed something else in our calculations. Dark matter advocators means that it is more plausible that our understanding of particle physics is lacking - there are more particles and symmetries and such out there to be found.

Non-particle proposals for the anomalous gravitational observations mentioned includes MOND (modified Newtonian dynamics) in which there is also a small correction term to the gravitational force. This correction term is small for objects with low acceleration. But for objects that have high acceleration, such as stuff rotating far from the galaxy center (centripetal acceleration) this term grows rather large. Furthermore there are also people re-investigating general relativity performing new calculation on rotational curves.

As mentioned by @Delta2 it is not understood how dark matter particles attain mass, there are many models out there. Dark sectors, as was mentioned, for instance. There are also supersymmetric models where the "Neutrialino" particle can make up dark matter. Such particle would gain some of its mass from the regular Higgs-mechanism and some of its mass from the mechanism that breaks supersymmetry (since supersymmetry is not an exact symmetry of nature at low energies it has to be broken somehow). There are also models with axion particles.
