Majoron

A majoron is a toy particle that some scientists believe might exist. It is a type of particle that does not interact with light, so we cannot see it. However, it is believed to be involved in a process called "spontaneous symmetry breaking" in some types of particle physics.

Think of it like a toy that only certain kids can see and play with, and it helps those kids break open a box of candy. The majoron is the toy, and the candy is the symmetry breaking process. Without the majoron, the kids cannot open the box of candy, and the candy remains hidden.

Some scientists believe that the majoron might also be involved in the decay of certain types of particles, but this is still being studied and debated among experts. In short, the majoron is a toy particle that is believed to help explain some mysterious phenomena in the subatomic world, and scientists are working hard to learn more about it.
