Juan José Giambiagi

Juan José Giambiagi (18 June 1924 – 8 January 1996) was an Argentine theoretical physicist. He was professor of the University of Buenos Aires but after a series of coup d'états in Argentina, he moved to Brazil. He is known for the discovery of dimensional regularization in quantum field theory.

Life Juan José Giambiagi was born in Buenos Aires in 1924. studied at the University of Buenos Aires (UBA) graduating in 1948, and obtaining a doctorate in physics in 1950. His thesis was titled "Application of the Hadamard method to some problems in mathematical physics" Under his direction, physicist Miguel Ángel Virasoro was recruited. and in Il Nuovo Cimento in November 1972. Veltman admitted to have seen drafts of Giambiagi and Bollini's work.

Both t' Hooft and Veltman were awarded the Nobel Prize in Physics in 1999 for "elucidating the quantum structure of electroweak interactions in physics.”, but the work of Giambiagi and Bollini was not cited in the document references. However, Veltman mentioned “the independent work of Bollini and Giambiagi,” in his Nobel lecture.

Honors and awards After the death of Giambiagi, the physics department at UBA was renamed the Juan José Giambiagi Department of Physics. At ICTP, the Giambiagi lecture hall was created.
