By John W. Moffat

One of the present books that remember the invention of the Higgs boson, Cracking the Particle Code of the Universe is a unprecedented aim remedy of the topic. The booklet is an insider's behind-the-scenes examine the arcane, interesting international of theoretical and experimental particle physics top as much as the hot discovery of a brand new boson. If the recent boson is certainly the Higgs particle, its discovery represents a major milestone within the heritage of particle physics. notwithstanding, regardless of the strain to award Nobel Prizes to physicists linked to the Higgs boson, John Moffat argues that there nonetheless stay vital facts analyses to be played ahead of uncorking the champagne.

John Moffat is Professor Emeritus of Physics on the college of Toronto and a senior researcher on the Perimeter Institute for Theoretical Physics. famous for his outside-the-box examine on themes reminiscent of darkish subject, darkish power, and the various velocity of sunshine cosmology (VSL), his new ebook takes a serious examine the hype surrounding the Higgs boson. within the technique, he provides a cogent and sometimes unique heritage of particle physics and an exploration of other theories of particle physics that don't function the Higgs boson, together with his personal. He offers a close and private description of ways theoretical physicists get a hold of new theories, and emphasizes how rigorously experimental physicists needs to interpret the advanced facts now popping out of accelerators just like the huge Hadron Collider (LHC).

The ebook doesn't draw back from debatable subject matters comparable to the sociology of particle physics. there's massive strain on tasks just like the $9 billion LHC to return up with optimistic leads to order to safe investment for the long run. but so far, the Higgs boson could be the merely optimistic consequence to emerge from the LHC experiments. The searches for darkish topic debris, mini-black holes, additional dimensions, and supersymmetric debris have all arise empty-handed, with critical results for theoretical physics, together with string conception and gravity theory.

John Moffat can be the writer of Reinventing Gravity (2008) and Einstein Wrote Back (2010).

Example text

It is about 200 times stronger than the electromagnetic force, which in turn is about 1038 times stronger than gravity. In the standard model of particle physics, the strong force is carried by the massless gluons, which bind quarks together in hadrons such as protons and neutrons, and thereby bind protons and neutrons together in atomic nuclei. During the past four decades, theoretical physicists have devoted much effort to attempting to unify the four forces of nature in a grand design. indd 16 11/1/2013 6:29:50 PM What Is Everything Made Of?

Gell-Mann never published his paper because he doubted whether experiments could verify his proposals. 22 Only in one of the last sections of the paper did he actually discuss his idea of the Eightfold Way in SU(3) as a possible description of strong interactions. In 1974, when Gell-Mann visited the University of Toronto as my guest, he advised me that when writing physics papers one should attempt to include all possible variants of the proposed theory in the paper, thereby preventing some future author from generalizing your theory and leaving you behind without credit.

Otherwise, the series will not converge to the exact solution. In particular, if we truncate the series at a certain term, we anticipate that the sum of the terms up to this point gives a good solution to the equations, which can then be compared with experiments. indd 18 11/1/2013 6:29:51 PM What Is Everything Made Of? 19 Dirac expressed his disapproval of renormalization theory with its reliance on perturbation theory: Most physicists are very satisfied with the situation. ” I must say that I am very dissatisfied with the situation, because this so-called “good theory” does involve neglecting infinities which appear in its equations, neglecting them in an arbitrary way.
