baryon decuplet and octet have same quark content, but has spin 1/2 and 3/2. So what gives octet the extra spin?
A baryon octet is a group of eight particles that are made up of three quarks each. These particles are the building blocks of protons and neutrons, which make up the nucleus of an atom.
The baryon octet has extra spin because each of the three quarks that make up the particle also have their own spin. When these spins are combined, they create an overall spin for the baryon octet that is greater than just the sum of the individual quark spins.
The extra spin of the baryon octet is significant because it helps explain the stability of the nucleus of an atom. The extra spin allows for the strong nuclear force to keep the protons and neutrons tightly bound together.
The extra spin of the baryon octet affects its properties by giving it a higher mass and a longer lifetime compared to other particles with less spin. This also contributes to its stability and ability to form larger structures like atoms.
Yes, the baryon octet's extra spin can be observed through experiments such as particle accelerators, where scientists can study the behavior of particles at high energies. The extra spin can also be calculated and predicted through various mathematical models and theories.
