content: The proton, a fundamental constituent of the atomic nucleus, seems to be smaller than was previously thought. And despite three years of careful analysis and reanalysis of numerous experiments, nobody can figure out why. The proton's problems started in 2010, when research using hydrogen made with muons seemed to show that the particle was 4% smaller than originally thought. The measurement, differed from those obtained by two other methods by 4%, or 0.03 femtometers. That's a tiny amount but is still significantly larger than the error bars on either of the other measurements. The latest experiment also used muonic hydrogen, but probed a different set of energy levels in the atom. It yielded the same result as the Nature paper — a proton radius of 0.84 fm — but is still in disagreement with the earlier two measurements. So what's the problem? There could be a problem with the models used to estimate the proton size from the measurements, but so far, none has been identified. The unlikely but tantalizing alternative is that this is a hint of new physics."http://www.nature.com/news/shrunken-proton-baffles-scientists-1.12289

content: The title of your thread is misleading, phonons are lattice vibrations in solids not = protons.

content: yes i confused photon with proton sorry dyslexia gets me again high IQ but cant spell sorryI'd have to say this is on par with the discovery of the quantum (ie photoelectric effect, double slit experiment)The explanation for the unexpected small size of the proton is probably something to do with the way that muons interact with protons. We assume that electrons and muons interact with protons in exactly the same way, but this is a hypothesis. There is very little observational evidence supporting the idea that electrons and muons behave in exactly the same way when they are bound to an atomic nucleus. The problem with this idea is that it requires that particle physics be extended beyond the standard model. It is also possible that the problem is something much more mundane, like a faulty connection somewhere in the experimental setup.yes we need an independent verification of this result before we start rewriting the textbooks but we can dream can't we

content: Quote from: Sionyn on January 26, 2013, 01:40:36 amPhoton, phonon and proton... those are three different words, for three different things.Anyway... personally I suspect this result just shows that the diameter of the proton varies, depending on what's going on nearby. Whispers.... Scalar Wave Metric... But of course that's *totally* woo-woo non-mainstream physics. And the recently discovered cyclical variations in isotope decay rates (that so far can't be explained by standard physics) couldn't be anything to do with scalar wave background noise from the Sun either.20130125http://arstechnica.com/science/2013/01/hydrogen-made-with-muons-reveals-proton-size-conundrum/Hydrogen made with muons reveals proton size conundrumA measurement that's off by 7 standard deviations may hint at new physics.by John Timmer - Jan 25 2013, 6:01am -1100http://news.ycombinator.com/item?id=5112094commentshttp://en.wikipedia.org/wiki/Dirac_equationhttp://www.sciencemag.org/content/339/6118/417Proton Structure from the Measurement of 2S-2P Transition Frequencies of Muonic Hydrogen.Aldo Antognini1,2,*,; François Nez3,; Karsten ...Trying to get the original paper - it's behind a paywall.
