The figure below from a DO Collaboration paper has been used as a proof for the non-existence of quark compositeness. But when we read the DO paper we clearly see that it refers to a very high compositeness scale in the TeV range (Take a look at the first three references of the DO paper), but as we see in the posts in this web page  BIASED NUCLEON STRUCTURE and The article PLOT OF THE WEEK – QUARK COMPOSITENESS IS NOWHERE NEAR is wrong the true compositeness scale is just 1 GeV and quark compositeness has not already been established because there is a complete entanglement between primons (prequarks) and valence quarks, and between valence and constituent quarks, besides the fact that primons should be very light. What the quark compositeness searches in the TeV range yield is, actually, that primons (prequarks) are not composite. Therefore, the quark compositeness searches in the TeV range are completely misleading.

It is worth recalling that electrical charges do not appear in Bjorken scaling structure functions. And also we should have in mind that at high q square the de Broglie wavelength h/q is very small and, thus, we probe the 3 inner prequarks in the nucleon and identify them as being 3 valence quarks due to the lack of identification of their electrical charges.

The first three references of the above paper are:

This also means that other experiments on quark compositeness carried out in the TeV region produce null results, of course. A good account of this can be found in this ATLAS Report.

The Multi-Bang Universe: The Never-Ending Realm of Galaxies

In this article a new cosmological model is proposed for the dynamics of the Universe and the formation and evolution of galaxies. It is shown that the matter of the Universe contracts and expands in cycles, and that galaxies in a particular cycle may have imprints from the previous cycle. It is proposed that RHIC’s liquid gets trapped in the cores of galaxies in the beginning of each cycle and is liberated with time and is, thus, the power engine of AGNs. It is also shown that the large-scale structure is a permanent property of the Universe, and thus, it is not created. It is proposed that spiral galaxies and elliptical galaxies are formed by mergers of nucleons vortices (vorteons) at the time of the big squeeze and immediately afterwards and that the merging process, in general, lasts an extremely long time, of many billion  years. The evaporation rate of RHIC’s liquid is calculated with Quasar PDS 456 data and the true nature of the concentrated mass at its center is revealed. It is not a Black Hole but the mass is of the same order of the supposed Black Hole. It is concluded that the Universe is eternal and that space should be infinite or almost. The paper has been published on March 15, 2007 by Frontiers in Science. Here is the link for accessing the paper.


I was alerted by an important Particle Physics physicist on Robert Hofstadter results about the nucleon structure cited by me by means of the reference Rev. Modern Phys. Vol. 28, 214, 1956. He sent me the very important reference by R. Hofstadter, F. Bumiller and M. R. Yearian, Electromagnetic Structure of the Proton and Neutron (Rev. […]

Neutrino Oscillations Hint at a New Fundamental Interaction

In a publication from 2012 the Daya Bay Collaboration reported a  disappearance of about 6% of electron antineutrinos along a distance of 1648 m and claimed that this disapearance was caused by neutrino oscillations. But in a paper that has just been published this collaboration corrects the old result because now it has found that the […]

The article Plot of the week – quark compositeness is nowhere near posted in Tommaso Dorigo’s blog is wrong. After reading this post, please take a look at the post BIASED NUCLEON STRUCTURE. As I explain in the paper The Higgs Boson and Quark Compositeness (presented at Moriond 2014), and in its presentation, and in the paper Weak decays […]

Towards a solution for the weak radiative hyperon decays puzzle

The weak radiative hyperon decays problem is a long standing puzzle of about 50 years. It has its origin in the results of experiment [1] which showed a large asymmetry in the decay  Sigma+  >  p gamma, violating, thus, Hara’s theorem [2] which, at the hadron level, states that the parity-violating amplitude of the above […]

A Preliminary Explanation for the Pentaquark found by LHCb

The paper has recently been published in the Journal of Nuclear and Particle Physics. I propose that the two resonant states of the recently found pentaquark by LHCb with masses of 4380 MeV and 4450 MeV are two states of the hadronic molecule ccbar + proton with similar properties to those of the Karliner-Lipkin pentaquark.

Quark decays via virtual Higgs-like bosons

The figure below is part of the paper presented at Moriond 2014. See the whole paper at the link. The transition from b to c is compatible with BaBar results as shown in BaBar’s paper.     Abstract Considering that each quark is composed of two prequarks it is shown that the recently found Higgs boson belongs […]

The Higgs-like Bosons Couplings to Quarks at Journal of Nuclear and Particle Physics

Abstract The allowed and suppressed Higgs-like bosons couplings to quarks are identified. The relative ratios of strengths of allowed couplings are calculated. The latter is extremely important for experimentalists in the determination of the nature of the recently found Higgs boson and in the search for the charged Higgs-like bosons. Keywords Higgs Boson, Higgs-like Bosons, […]
