According to Charles Seife's article in the

*June 10th, 2005* issue of

*Science*, KEK has discovered two bizarre particles:

The numbers indicate masses in MeV. The lighter one (which is a sharper resonance) is most likely a bound state of D0 and D0*, analogous to the nuclei that are bound states of protons and neutrons. The heavier one is more puzzling, and a leading conjecture is that it is an example of a long-sought hybrid meson, i.e. a bound state of quarks connected by an excited (QCD) string - excuse me - an excited gluon fluxtube. Its mass is less sharply well-defined and it often decays to J/psi which a bound state of mesons would not do. More mundane explanations have not been ruled out yet.

Lubos, be assured that the mass difference here has nothing to do with super strings, but it is a good indication that QUITAR theory is on the right track.

ReplyDeleteIn GUITAR the fundamental mass unit is 1/alpha times the rest mass of electon, so that the electron mass equals alpha in fundamental mass unit.

Here, the mass difference is 70 MeV, that is almost exactly ONE fundamental mass unit. 70 MeV/electron mass = 70Mev/0.511Mev = 137 = 1/alpha. The disrepancy away from being exactly one unit, is due to experimental error, plus the mass correction (about 3 to 4 electron mass) due to decay lifetime of the particles detected.

Whether you accept GUITAR or not, you have to agree that 1/alpha of electron mass is the important fundamental characteristic mass.

quantoken,

ReplyDeleteyou are right; I do not know about GUITAR, and I would like to look it up (where?); I am also involved in phenomenological and modeling work with the 70 MeV/c2 mass unit:

http://particlez.org/p3a

specifically on Belle's X mesons, in my recent preprint the meson mass grid is used to identify the two states as chi_c(1); this is in agreement with the recent result by Belle that the X(3872) is a 1++:

in the particlez.org/p3a archive see also the postprint of a recent review paper by Malcolm H. Mac Gregor, who has studied the 70 MeV/c2 mass quantum for decades; his alpha-based lifetime quantization is equally impressive;

Wow, massgrid:

ReplyDeleteI am glad you find my posts and I find yours. I knew absolutely nothing about Malcolm's research whatsoever, and did not know that he arrived at the same fundamental mass unit as mine.

GUITAR is a theory I am developing that when finished, would derive both the QM and GR as we know it, and explain away the inconsistency between the two. The fundamental principle is that quantum information is the basic construction element of the universe, and the total quantum information is a discrete and fixed quantity. Spacetime itself, as well as all physica measurements, are derived from quantum information. The fact that quantum information is NOT infinity necessarily leads to a finite spacetime, which has to be curved to be finite, and curved spacetime naturally leads to gravity and Einstein's GR. On the otherhand, discreteness and conservation of quantum information would lead to uncertainty principle and the rest of QM.

GUITAR is a self-consistent theory and is consistent with all physics and astronimical observational facts we know so far. But the exact mathematical formulation has not been completed yet.

I came to the 70MeV natural mass unit NOT from observation of any experimental data, but from pure reasoning. The reasoning is that we know that the mass-energy of an electron is purely due to the field energy of the elctric field around the electron, so, since alpha stands for the interaction strength of the electromagnetic force, the electron mass has to be something proportional to alpha times the fundamental mass unit. So the simplest selection would be

Me = alpha * M0. Plug in known mass of the electron, you get the mass unit to be about 70 MeV.

I was able to calculate the precise mass of neutron,

completely within experimental error, among other amazing results. See this link.well, quantoken,

ReplyDeleteyour unification goal is ambitious, but, why not? someone, someday, must get there;

talking about the electron, have a look at Malcolm Mac Gregor's book "The enigmatic electron"; Malcolm also has a contribution in "What is the Electron?", a collection of 10 essays recently published by Apeiron;

my interest is particle systematics, and I work bottom-up from the data (masses etc.), looking for regularities with an open mind; the equivalent of Kepler's laws or Balmer's rule for particles has not been found yet, although some people believe that they have the final theory already; we shall see;

good luck,
