Antimatter is a bit like the “twin of normal matter” “Demons”, but they are surprisingly similar-in fact, the only real difference is that antimatter has an opposite charge. This means that if a matter and antimatter particles come into contact, they will annihilate each other in an energy burst.

What’s more complicated is that some particles such as photons are actually their own antiparticles. Some are even considered strange mixtures of two states at the same time, thanks to the quantum properties of superposition. This means that these particles actually oscillate between matter and antimatter.

Now, a new kind of particle has joined this exclusive club-Charm Meson. This subatomic particle is usually composed of a charm quark and an up antiquark, and its antimatter equivalent is composed of a charm antiquark and an up quark. Usually these two states are separate, but new research shows that charm meson can switch between these two states automatically.

This incredibly accurate measurement was derived from data collected by Oxford University physicists during the second operation of the Large Hadron Collider. Charm mesons are produced in the proton-proton collision of the Large Hadron Collider, and they usually decay into other particles after only a few millimeters of propagation.

By comparing the charm meson, which tends to go farther, and the charm meson, which decays faster, the research team determined that the difference in quality is the main factor in determining whether the charm meson will become an anti-charm meson.

This absolutely tiny discovery may have implications for the universe big influence. According to the standard model of particle physics, the Big Bang produced equal amounts of matter and antimatter. Over time, all matter will collide and annihilate, leaving the universe blank. Obviously, this did not happen, and matter somehow dominated, but what caused this imbalance?

The hypothesis proposed by this new discovery is that the frequency of the conversion of particles like charm meson from antimatter to matter is higher than the frequency of their conversion from matter to antimatter. Investigating whether this is true—if it is true, and why—may be an important clue to one of the biggest mysteries in science.
