Tadpole (physics)
In
mass scale in the loop integral
).
Tadpole corrections are needed if the corresponding external field has a non-zero vacuum expectation value, such as the Higgs field.[1]
Tadpole diagrams were first used in the 1960s. An early example was published by Abdus Salam in 1961, though he did not take credit for the name.[2] Physicists Sidney Coleman and Sheldon Glashow made an influential use of tadpole diagrams to explain symmetry breaking in the strong interaction in 1964. [3]
In 1985 Coleman stated (perhaps as a joke) that Physical Review’s editors rejected the originally proposed name "spermion".[4][5]
