ydinprotonien
Ydinprotonien is a hypothetical class of subatomic particles proposed in speculative physics discussions of nuclear matter. The term is used in some theoretical models to describe a conjectured, baryon-like excitation that could arise in extremely dense nuclear environments or in high-energy collisions. In these proposals, ydinprotonien would be a hadron-like state with baryon number +1 and electric charge equal to the proton’s, making it a positively charged, heavy partner of the proton. The mass is model-dependent, but such states would be heavier than the ordinary proton and typically short-lived, decaying via strong or weak processes to lighter baryons and mesons.
Predicted properties vary between models, but common themes include a strong coupling to the nuclear medium
As of now, ydinprotonien remain speculative and have not been observed experimentally. They are discussed mainly
