<\/p>\nDimensional regularization, that is compute in “4 + ε space-time dimensions” and take the limit ε→0 at the end, is a powerful tool in quantum field theory. In fact, Veltman and \u2019t Hooft won the 1999 Physics Nobel Prize, for dimensional regularization and its application to Yang-Mills theory. The work of Veltman and ‘t Hooft dates back to 1971 and was published in 1972 [3].<\/p>\n
However, the original idea may have come from two physicist working in Argentina. According to Wolfgang Bietenholz & Lilian Prado, it was Juan Jose Giambiagi and Carlos Guido Bollini [1] in a paper submitted before Veltman and ‘t Hooft, who first proposed dimensional regularization [2]. <\/p>\n
The paper of Giambiagi and Bollini, although submitted for publication earlier, was actually published after the paper of Veltman and ‘t Hooft.<\/p>\n
