Mohammad Abdus Salam [4] [5] [6] (/ s æ ˈ l æ m /; pronounced [əbd̪ʊs səlaːm]; 29 January 1926 – 21 November 1996) [7] was a Pakistani theoretical physicist.He shared the 1979 Nobel Prize in Physics with Sheldon Glashow and Steven Weinberg for his contribution to the electroweak unification theory. [8]
Weak neutral currents were predicted by electroweak theory developed mainly by Abdus Salam, John Clive Ward, Sheldon Glashow and Steven Weinberg, [3] and confirmed shortly thereafter in 1973, in a neutrino experiment in the Gargamelle bubble chamber at CERN.
In physics, the Pati–Salam model is a Grand Unified Theory (GUT) proposed in 1974 by Abdus Salam and Jogesh Pati.Like other GUTs, its goal is to explain the seeming arbitrariness and complexity of the Standard Model in terms of a simpler, more fundamental theory that unifies what are in the Standard Model disparate particles and forces.
Sheldon Glashow, [1] Abdus Salam, [2] and Steven Weinberg [3] were awarded the 1979 Nobel Prize in Physics for their contributions to the unification of the weak and electromagnetic interaction between elementary particles, known as the Weinberg–Salam theory.
A neutrino (/ nj uː ˈ t r iː n oʊ / new-TREE-noh; denoted by the Greek letter ν) is an elementary particle that interacts via the weak interaction and gravity. [2] [3] The neutrino is so named because it is electrically neutral and because its rest mass is so small that it was long thought to be zero.
An event in which the electron and neutrino changes momentum and/or energy by exchange of the neutral Z 0 boson. Flavors are unaffected.. In a series of separate works in the 1960s Sheldon Glashow, Steven Weinberg, and Abdus Salam came up with a theory that unified electromagnetic and weak interaction between elementary particles—the electroweak theory—for which they shared the 1979 Nobel ...
In the 1960s, Sheldon Glashow, Abdus Salam and Steven Weinberg unified the electromagnetic force and the weak interaction by showing them to be two aspects of a single force, now termed the electroweak force. [8] [9] The existence of the W and Z bosons was not directly confirmed until 1983. [10] (p8)
This is a hallmark of a neutral current interaction and is interpreted as a neutrino exchanging an unseen Z boson with a proton or neutron in the bubble chamber. The neutrino is otherwise undetectable, so the only observable effect is the momentum imparted to the proton or neutron by the interaction. The discovery of the W and Z
