Ferdinando Gliozzi
Edit Profile
Ferdinando Gliozzi is an Italian theoretical physicist working in string theory, known for his research at the Istituto Nazionale di Fisica Nucleare and for co-developing the GSO projection, a fundamental result that removed tachyonic states and enabled spacetime supersymmetry, playing a decisive role in establishing the consistency of superstring theory.
Education
He studied at the University of Turin.
Career
Gliozzi has worked as a theoretical physicist at the Istituto Nazionale di Fisica Nucleare, focusing on the theoretical structure of string theory. In collaboration with David Olive and Joël Scherk, he introduced the GSO projection, a decisive development that eliminates tachyonic states from the Neveu–Schwarz sector while selecting a consistent spectrum of physical states. This construction made it possible to realize spacetime supersymmetry in string models and became a central element in the formulation of modern superstring theory, shaping the direction of the field during its formative period.
