Here: Physics Discussion Forum • Index page

In another board, Farsight and I had had this exchange:
Farsight wrote:
lpetrich wrote:The mystery of mass is:
What fixes the rest masses of the massive elementary particles
What does so in a fashion consistent with the symmetries of the unbroken Standard Model
One needs Higgs doublets or some equivalents for those.
Hurry up and move the goalposts quick, because that's not how it's been sold to a gullible public. This is how it's been sold: Elementary particle masses are thought to come about from the interaction with the Higgs field. It's garbage. I know it, you know it, and soon everybody will know it.

That's rather typical of what he thinks about the Higgs particle.

:cheers: Yep, that's how I remembered those "its garbage and you know it too" type posts. :rolleyes: Any sign of a retraction anywhere yet? :smoke:

P.S. Having read the "mass made simple" topic on that board, It appears not (up to 4th July). lol

Some video:

Higgs Boson Discovery announcement by Peter Higgs - YouTube
Higgs boson update at CERN: July 4, 2012, press conference - YouTube
CERN Higgs Boson Discovery Seminar - YouTube
Latest update in the search for the Higgs boson (04 July 2012) - the slides

Quantum Diaries - New baby boson is born, weighing in at about 126 GeV - has some graphs showing the Higgs-particle-decay bumps
Quantum Diaries - New boson could pave the way towards new discoveries - mentions supersymmetry-model constraints

Next: atom-smashers with gold-plated diamonds | COSMOS magazine
Particle detectors made from thin-film artificial diamonds are likely more radiation-resistant than the silicon detectors that are currently being used.

The Decades-long Search for the Higgs | SLAC News Center

New boson sparks call for 'Higgs factory' - physicsworld.com - proposes a muon collider to make lots of Higgs particles. I'm skeptical, because muons have a mean life of about 2.2 microseconds. That's a half life of 1.56 microseconds. That does not exactly allow much margin for error.

As far as I know, experiments at these energy levels haven't produced any practical benefits, and I don't know of any reason to expect that to change.

Nobody expected any benefits from understanding the photon either...

From the big announcement thread:

---
[snip]

Over sufficiently long times, basic research has historically tended to be the very best investment one can make. And quite possibly particle physics will be no exception. But I rather expect that the great technological consequences of particle physics will rely more on the development of theory than on more results from experiment. If one figures out how to create energy from the vacuum or transmit information faster than light, it’ll surely be done by applying the theory in new and unexpected ways, rather than by using specific experimental results.

One would think the value of basic research is well understood, yet emphasis on applied research is quite wide spread, not only among business and politics. This should probably be debated more.

Yup.

Lots of people complained about the money spent to test Einstein's theories. I'd say it was worth it.

The higher their speed, the longer their half-life, due to time dilation.

You know that all that works out to 42 don't you?

True, but getting a muon up to 100-GeV energies gives it a time dilation of about 1000, pushing its lifetime up to a few milliseconds. Not much of an improvement.

So one may have to catch both the positive muon and the negative muon from a pair-production event, and accelerate both of them.

CERN discovers Higgs-like boson - physicsworld.com
It's a boson, but what sort? - physicsworld.com

Look at John Duffield's arguments in the comments. Some of you people may find them rather familiar.

In particular, his argument about the mass of baryonic matter is a red herring. It's true that about 98% of nucleons' masses come from quark and gluon kinetic and interaction energies, as a result of color confinement, another 1% from electromagnetic effects, and another 1% from quark rest masses. But nucleons are bound states of multiple Standard-Model particles, not Standard-Model particles themselves.

I guess you're saying he's mistaken Ipe? Surely he'll receive the relevant information as the discussion goes on? ;)
