Could someone please tell me the difference between tree diagrams and loop diagrams? If I'm thinking correctly tree diagrams are before contracting? Also how do vacuum diagrams fit into the picture?
Thanks!
Thanks!

No, vacuum diagrams are diagrams without external legs.Higgsy said:And vacuum diagrams are just diagrams without vertices?
Vacuum diagrams, also known as Feynman diagrams, are graphical representations of mathematical equations used to visualize and calculate the interactions between particles in quantum mechanics. Tree diagrams are diagrams that show the possible outcomes of a series of events or decisions. Loop diagrams are diagrams used in circuit analysis to represent the flow of current.
These diagrams are used to help scientists understand and predict the behavior of particles, systems, and circuits. They also aid in visualizing complex mathematical equations and relationships.
Vacuum diagrams focus on particle interactions in quantum mechanics, while tree diagrams are used to analyze series of events or decisions. Loop diagrams are specific to circuit analysis and show the flow of current. Additionally, vacuum and tree diagrams are used in theoretical physics, while loop diagrams are used in electrical engineering.
All three types of diagrams are visual representations of complex systems or equations. They are also used to make predictions and calculations about the behavior of particles, systems, and circuits.
These diagrams are often used in theoretical and experimental research to visualize and analyze complex mathematical equations and systems. They are also used to make predictions and verify experimental results in various fields, such as quantum mechanics, astrophysics, and electrical engineering.
