Quark Compositeness and the Proton Radius Puzzle

The proton radius puzzle comes about from the discrepancy between measurements for the proton radius using electrons and using muons. The current CODATA data for only electronic spectroscopy data is 0.8758(77) fm . Including electron scattering results, CODATA finds the overall result of 0.8775(51) fm. The first results of muonic hydrogen (Collaboration of Randolf Pohl et al.) based on the 2S-2P Lamb shift energy splitting yields  0.84087(39) fm for the proton radius. This is 4% smaller than the CODATA radius, and is a 7σ discrepancy. The latest results of the same collaboration confirms this result. Why is there this discrepancy?

The discrepancy comes from the fact that, as muonic hydrogen has a very short radius, it is more sensitive to the true electric charge distribution which, on the other hand, cannot be explained by three pointlike quarks, as shown in the post The article PLOT OF THE WEEK – QUARK COMPOSITENESS IS NOWHERE NEAR is wrong in this web page. Therefore, the above mentioned discrepancy has to do with quark compositeness.

For a broad account of the proton radius puzzle, please take a look at the paper by Carl E. Carlson The Proton Radius Puzzle. For the latest theoretical developments, please take a look at the work of the TRIUMF group.

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 produced flux is 6% larger than what is predicted by the current nuclear models.

On the other hand there has been a recent report of a new fundamental interaction involving production of electron-positron pairs and neutrino-antineutrino pairs by means of the decay of its light vector boson.  J. L. Feng et al. analyzed the data of the paper and corroborated the paper’s results.

I take the new Daya Bay results as an indication of new Physics, extend them to the solar neutrino puzzle as a whole and link them to the newly found interaction. In my paper I propose that neutrino oscillations do not exist and, in the light of the latest results of July 2016 of the Daya Bay Collaboration and the recent discovery of this new fundamental interaction above mentioned, I propose that the neutrino production at the Sun’s core in the pp and CNO cycles can be much larger than what is predicted by the Standard Solar Model, exactly because of this new interaction. And thus, the claimed neutrino deficits on Earth would be completely misleading.


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 […]

The Higgs Parity has not really been determined yet.

At Moriond 2014, on March 23, there was the presentation by Nicola De Filippis on behalf of ATLAS and CMS collaborations: Measurements of the Higgs properties at LHC. Part of the presentation was on the Higgs parity which had been determined to be even. At the end of his talk there was a hot discussion on the […]

  In almost all books of Introduction to Particle Physics one finds this picture of the proton structure function F2 in terms of x for  q squared around 1 GeV squared. The authors state that this picture proves that there are 3 valence quarks in the proton, but this is completely false because the mass […]

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 […]

Charmonium with an effective Morse molecular potential

At BEACH 2014 I presented the paper Charmonium with an effective Morse molecular potential which has recently  been published in the proceedings. In this paper I propose a completely new approach to charmonium spectroscopy. This approach allows the calculation of the parameters of the molecular potential, calculation of the radii of 5 S states, and information […]

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.

The Rotation of Spiral Galaxies

The rotation of spiral galaxies is completely described in my paper A New Model without Dark Matter for the Rotation of Spiral Galaxies presented at the APS April Meeting in Denver, CO, USA, in 2013. The paper clearly shows that dark matter does not exist in spiral galaxies. Important consequences for galactic evolution and the […]
