Definition of WEINBERG-SALAM THEORY: A unified theory of weak and electromagnetic interactions between particles. It predicted the existence and behaviour of the Wf, W and Z Science Dictionary The World's Largest Online Science Dictionary. source of quark mass in the Weinberg Salam theory is the Yukawa couplings.) It then follows that the pion is massless, at least insofar as it is re- garded as an unperturbed state of . accomplished by the Glashow–Salam–Weinberg electroweak theory [47, 40] with gauge group H = SU(2) × U(1). By elaborating the theory with an additional “Higgs field,” one avoided the massless nature of classical Yang–Mills waves. The. Glashow{Weinberg{Salam theory is a uni ed theory of weak and electromagnetic inter- actions. EM. a(a= 1;2;3) and B, one linear combination remains mass- less and gives rise to the electromagnetism, while 3 other linear combinations become massive and give rise to the weak interactions. The Weinberg-Salam Model The Electroweak Theory was proposed in the late s by Weinberg, Salam, and Glashow. Four massless mediating bosons are postulated, arranged as a triplet and a singlet as members of multiplets of “weak isospin” I and “weak hypercharge” Y W. The resulting theory is known as GWS model. It was flrst formulated by Weinberg in and by Salam in independently. The essay is formulated as follows. First in order to built the theory of weak interaction, some properties of weak interaction are discussed. Weinberg, Salam and Glasho own physics * In our next issu we e wil covel r the awar odf the Nobe0 l Physics Prize to J.W. Cronin and V.L. Fitch. Last year the Nobel Prize for physics was awarded to Steven Weinberg, Abdus Salam and Sheldon Glashow for the development of the theory which unifies electromagnetic and weak interactions*. Electroweak interaction. Sheldon Glashow, Abdus Salam, and Steven Weinberg were awarded the Nobel Prize in Physics for their contributions to the unification of the weak and electromagnetic interaction between elementary particles. The existence of the electroweak interactions was experimentally established in two stages. Unified field theory. Classically, however, a duality of the fields is combined into a single physical field. For over a century, unified field theory remains an open line of research and the term was coined by Albert Einstein, who attempted to unify his general theory of relativity with electromagnetism. action by a single theory certainly is one of major achievements of the physical science in this century.
