In the world of particle physics, the study of subatomic particles and their interactions, there is always something new to discover. Recently, a team of physicists made an intriguing observation that suggests the presence of diquarks in baryons, a finding that could have significant implications for our understanding of the fundamental building blocks of matter.
First, let’s define some terms. Baryons are a class of subatomic particles that include protons and neutrons, which make up the nucleus of an atom. Diquarks, on the other hand, are hypothetical particles made up of two quarks that are bound together by the strong nuclear force. Quarks are the smallest known particles that make up protons and neutrons, and they come in six different “flavors” (up, down, charm, strange, top, and bottom).
The observation in question was made by a team of physicists at the Large Hadron Collider (LHC), a particle accelerator located in Switzerland. They were studying collisions between protons and lead ions, looking for evidence of strange matter. Strange matter is a hypothetical form of matter that contains strange quarks, which are heavier and more unstable than up and down quarks.
What the physicists found was unexpected. They observed an excess of certain types of baryons that contained strange quarks, specifically those with a particular combination of spin and isospin (a quantum property related to the strong nuclear force). This excess could not be explained by known physics, leading the researchers to suggest that diquarks may be involved.
The idea is that diquarks could be formed within the baryons during the collisions, and these diquarks could then combine with strange quarks to form the observed baryons. This would explain why there was an excess of baryons with a specific spin and isospin combination – it would be a result of the properties of the diquarks involved.
This observation is significant because it provides evidence for the existence of diquarks, which have been a topic of debate in the world of particle physics for decades. While they are still considered hypothetical particles, their potential existence has been suggested by various theoretical models. If diquarks do exist, they could have important implications for our understanding of the strong nuclear force and the structure of baryons.
It’s worth noting that this observation is still preliminary and will need to be confirmed by further experiments. However, it’s an exciting development in the ongoing quest to understand the fundamental nature of matter. As physicist and author Sabine Hossenfelder wrote in a recent blog post, “It’s always a good day when we learn something new about the universe.”
