The natural next step is to investigate what minimal extensions of the Standard Model
can lead to a strong electroweak transition; what is the transition temperature and dynamics of the transition; and how do the resulting constraints on these theoretical extensions compare with the steadily improving experimental constraints from collider experiments.
The British theoretical physicist, 84, told BBC Radio 4's 'The Life Scientific' that he could have been among Shelley Glashow, Abdus Salam and Steven Weinberg, who received a Nobel prize in 1979 for their the Standard Model
According to the Standard Model
, everything, from flowers and people to stars and planets, consists of just a few building blocks: matter particles.
Supreme Court discards or significantly tailors the Standard Model
These papers present the first observations of a new particle discovered by two big experiments at the Large Hadron Collider (LHC) in the search for the Standard Model
Higgs boson which has spanned many decades and has involved many experiments," explains physicist Joe Incandela, spokesperson of the CMS experiment.
of California-Davis) show that the Einstein equations for a spherically symmetric spacetime in Standard Schwazschild Coordinates close to form a system of three ordinary differential equations for a family of self-similar expansion waves, and that embedded as a single point in this family is the critical (k = 0) Friedmann universe associated with the pure radiation phase of the Standard Model
With the Higgs field, physicists completed the standard model
, which accurately describes the behaviors of all known particles and forces (except gravity).
There's only a five-speed gearbox but this spacious little car buzzes along with a distinct sense of urgency that definitely sets it apart from the standard model

But the Standard Model
doesn't explain things such as why the universe is almost all matter with only a little bit of anti-matter.
But the sums do not quite add up for the Standard Model
to be true if these particles are considered alone.
Theoreticians had proposed, and experimenters were verifying, the standard model
of particle physics, a detailed but incomplete picture of matter and its interactions.
