Weinberg, Salam and Dr. Sheldon Lee Glashow, a high school classmate of Weinberg who had resolved a critical problem with the Weinberg-Salam model, were jointly awarded the 1979 Nobel Prize "for their contributions to the theory of the unified weak and electromagnetic interaction between elementary particles."
The rst eld theory solutions describing stationary vortons were found in the global limit of Witten's model, when the gauge elds vanish [8]. Multisphalerons in the Weinberg-Salam theory. A brilliant way out of this was found by Higgs, Steven Weinberg and Abdus Salam.
The ensuing low energy theory coincides with the standard bosonic Weinberg-Salam Model in the Coleman-Weinberg limit of the Higgs potential, except that now the couplings are not independent but . Its energy is the height of the barrier for tunneling between "topologically distinct" vacuums.
1. Using the semiclassical WKB approximation and Hamilton-Jacobi method, we solve an equation of motion for the Glashow-Weinberg-Salam model, which is important for understanding the unified gauge-theory of weak and electromagnetic interactions.

Also no there is nothing basic about Pati-Salam..(that includes Weinberg-Salam theory) Edited July 22, 2016 by Mordred In other words, we could in principle from the very beginning view $\tilde{G}$ as the gauge group of the theory, cf. We show that the configuration space of the classical, bosonic Weinberg-Salam theory has a non-contractible loop. Crucially, this reassured physicists that they could make reliable predictions about nature using the Weinberg-Salam theory of weak and electromagnetic interactions. Its energy is the height of the barrier for tunneling between "topologically distinct" vacuums.
California Institute of Technology, Pasadena, CA 91125, USA Received 30 November 1978 Various conditions necessary for the self-consistency of the Weinberg-Salam model are used to place constraints on fermion and Higgs Boson masses. Divergences are treated by the dimensional regularization method. Jones Abstract We establish the existence of multivortices arising in the self-dual . a static, but unstable, classical solution) suggests the existence of another sphaleron S * in the Weinberg-Salam theory.
This probably implies that there is an unstable, static, finite-energy solution of the field equations.

We show that the configuration space of the classical, bosonic Weinberg-Salam theory has a non-contractible loop. 24 in 1999 't hooft and veltmann received the same honor "for elucidating the quantum (subject to off hand memory though). Also known as Salam-Weinberg theory. 0. Specifically, we have two types of interactions It was rst formulated by Weinberg in 1967 and by Salam in 1968 independently.

Furthermore, it has a large magnetic dipole moment and its baryonic (and leptonic) charge is . Definition of 'Weinberg-Salam theory' Weinberg-Salam theory in American English (wainbrslm) noun Physics See electroweak theory Most material 2005, 1997, 1991 by Penguin Random House LLC. We show that the configuration space of the classical, bosonic Weinberg-Salam theory has a non-contractible loop. We give a close approximation to a static, but unstable, solution of the classical field equations of the Weinberg-Salam theory, where the weak mixing angle w is considered to be small. From an Unfavourable Reception to the Acceptance of the Standard Model

For small n the energies of the . Course Info. We will argue that why the symmetry spontaneous breaking is essential to approach the theory of weak interaction. perconducting strings exist in the Weinberg-Salam theory [7], vortons are potentially possible also there. 4.1. New York, NY: John Wiley & Sons, 1984.

We give a close approximation to a static, but unstable, solution of the classical field equations of the Weinberg-Salam theory, where the weak mixing angle w is considered to be small.

Section III below. We calculate the tunneling rate of the massive charged W-bosons in a background of electromagnetic field to investigate the Hawking temperature of black . Our construction covers all SU(2) topological sectors with vanishing U(1) magnetic flux and would be usable for a description of the baryon number non-conservation.
Its energy increases from 8 TeV to 14 TeV as the Higgs coupling runs from 0 to . The theory due to Glashow, Weinberg, and Salam unifying the weak force and electromagnetic force into a single "electroweak force." See also: Electroweak Force .

In 1979 Glashow, Salam and Weinberg were awarded the Nobel Prize for Physics for "for their contributions to the theory of the unified weak and electromagnetic interaction between elementary particles, including, inter alia, the prediction of the weak neutral current." The W and Z particles were then detected for the first time in 1983 at CERN. Free Online Library: Tunneling Glashow-Weinberg-Salam Model Particles from Black Hole Solutions in Rastall Theory.
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We present a new type of spherically symmetric monopole and dyon solutions with the magnetic charge 4/e in the standard Weinberg-Salam model. For their insights, Glashow, Salam, and Weinberg were awarded the Nobel Prize in Physics in 1979. We establish an upper bound on this energy of order 10 TeV. For this we consider a three-brane that moves under the influence of seven dimensional pure Einstein gravity.
These vortons have approximately equal radius and thickness, like a Horn torus .
