What is "hyperhelium"? Google only turns up things related to this article.
- Jabbles 2y ago2nd paragraph of TFA
- godelski 2y agoFor those that can’t RTFA, here’s the first sentence of the second paragraph > Hypernuclei are exotic nuclei formed by a mix of protons, neutrons and hyperons, the latter being unstable particles containing one or more quarks of the strange type.
- elashri 2y agoIt is an exotic nucleus composed of two protons, one neutron, and one lambda particle (which is a type of hyperon -fermions with three quarks- containing a strange quark). This configuration distinguishes it from regular helium-4, which consists solely of protons and neutrons. The inclusion of a lambda particle introduces "strangeness" into the nucleus, making it a hypernucleus [1]. PS: By exotic here it I use the term as used by particle physicists which just mean not your ordinary stuff discussed in the "popular" working groups. Not the linguistic meaning of the word exotic.

- bilsbie 2y agoWhat are the properties of this? Any cool applications?
- mrguyorama 2y agoIt decays in under a nanosecond. A reality of all exotic matter research is that it is exotic almost always because it cannot exist in a stable manner for longer than a second. The vast majority of applications, if any, will be extremely niche sensing applications. They are useful to further probe the edges of our knowledge of physics and look at the corner cases where our models give confused shrugs and odd answers. It's not going to power a warp drive.

- pfdietz 2y agoThere has been an idea that quark matter with roughly equal numbers of up, down, and strange quarks could be absolutely stable, the ground state of nuclear matter. Ordinary charged nuclear matter would be inhibited from converting to it (or being absorbed into it) by a strong potential barrier at its surface. However, if this were true neutron stars would actually be quark stars. There is some evidence that this isn't so, so the theory is not held to be very likely these days.
- cogman10 2y agoLHC likely created these particles which means we have single atoms that have been created and not full compounds. Someone can correct me if I'm wrong, but the significance of this is mostly just further confirmation of the predictions of the standard model. The standard model says such particles should exist and now that we've created them, we've confirmed that they do indeed exist. I don't think there's much practical application beyond further refinement of theoretical physics and ruling out other candidate theories.
- ninalanyon 2y agoExotic is defined in the Cambridge Dictionary as: "unusual and exciting because of coming (or seeming to come) from far away, especially a tropical country" That doesn't seem too far from the use of it in physics. The "tropical country" part is clearly optional but could be replaced by "especially a special group of scientists".
- brian-armstrong 2y agoPerhaps searches for exotic matter should take place in tropical regions?
