Changes in a strong nuclear force affect the spin of phi mesons.

When the phi meson spins the string between quarks harvests energy. Then that energy pushes those particles away from each other. So the phi meson is acting like an energy harvester. If that particle exists longer time, that thing could use to measure the differences in energy levels around it. The energy harvester is a system that is two balls that are orbiting each other. 

When there is an antenna like a metal wire or laser ray between them that system sends electromagnetic wave movement to the sides of that energy harvester. And maybe in the future. These kinds of systems can use to create clean energy in space. 

The new research has shown that the changes in strong nuclear force can affect the spin of so-called Phi-mesons that include two quarks. The image above this text shows the spin of phi mesons. The quarks are orbiting each other and their common quantum field forms the phi-meson. The axle of the phi-meson seems to be in the middle of those two quarks. And this thing is remarkable. 

Could in the middle of those two quarks be some kind of particle? And could that hypothetical particle be the "quantum" the hypothetical elementary particle that is involved in all material and particles? The thing that makes phi-meson exist only a short moment. Then the two quarks that are forming this particle fly away. 

"Collisions of heavy ions “melt” the boundaries of individual protons and neutrons, setting free the quarks and gluons normally confined within to create a quark-gluon plasma (QGP). Scientists look for spin alignment preferences among particles emerging from the QGP by tracking the distribution of their decay products relative to an imaginary line drawn perpendicular to the reaction plane of the colliding nuclei.

In some theories, the phi meson is the proto-particle. That was dominating material before the first hadrons formed after the Big Bang. In that model, high energy levels in the young universe kept those particles in form and they could form so-called mesonic material. Today that form of material does not exist anymore. But in the high-energy young universe, there is a possibility that phi mesons could form molecular-looking structures. 

Brookhaven laboratory made the impact tests with heavy ions. In that kinds of tests, the heavy ions are forming very hot debris. That debris is the quark-gluon plasma that is the most high-energy material in the world. That plasma is used for simulating conditions just after the Big Bang. But there is a possibility that the impacts of the heavy ions can use to form long-term phi mesons. The phi mesons require a very high energy level for forming. And a higher energy level means a longer lifetime. 

Those mesons can use to measure things like dark energy. The idea is when the phi meson spins it forms a sensor that could harvest the dark energy. If dark energy is forming strings or extremely thin magnetic fields. And then the phi meson impacts with those strings that should affect their spin. But that requires an extremely high energy level.
