The J/Psi particle is a subatomic particle made up of a charm quark and an anti-charm quark. Its excited states are higher energy states of the J/Psi particle, created through the addition of more energy.
The main difference between the J/Psi particle and its excited states is their energy levels. The excited states have higher energy levels due to the addition of more energy, while the J/Psi particle is the ground state with the lowest energy level.
The J/Psi particle and its excited states are studied through high-energy collisions in particle accelerators, such as the Large Hadron Collider (LHC). These collisions allow scientists to observe the properties and behavior of these particles.
Studying the J/Psi particle and its excited states can provide valuable insights into the fundamental forces and building blocks of the universe. These particles can also help us understand the behavior of matter and antimatter, and potentially lead to new discoveries in particle physics.
While the study of the J/Psi particle and its excited states is primarily focused on fundamental research, there have been some practical applications. The discovery of the J/Psi particle helped confirm the existence of a new type of quark, and its excited states have been used in medical imaging technology, such as PET scans, to detect the presence of cancer cells.
