Sam Treiman

Sam Bard Treiman (Chicago, 27 de maio de 1925 — Nova Iorque, 30 de novembro de 1999) foi um físico estadunidense.

Realizou pesquisas fundamentais nos campos de raios cósmicos, mecânica quântica, plasma e gravidade. Contribuiu para o entendimento da interação fraca, sendo ele e seus estudantes creditados com o desenvolvimento do modelo padrão da física de partículas.^[2] Foi professor de física da Universidade de Princeton, membro da Academia Nacional de Ciências dos Estados Unidos e do grupo JASON. Foi aluno de Enrico Fermi e John Alexander Simpson.

• 1957 (com John David Jackson e Henry Wyld) - definitive theory of allowed beta decays, taking into account time and parity violations
• 1958 (com Marvin Goldberger) dispersion relations analysis of pion and nucleon beta decay, culminating in the Goldberger-Treiman relationship for the charged pion decay amplitude. This work eventually led to the hypothesis of the partially conserved axial vector current, known as PCAC and to a deeper understanding of spontaneously broken chiral symmetry of the strong interaction.
