WHERE TO LOOK FOR THE OTHER HIGGS-LIKE BOSONS?

Taking into consideration the above chart for quark transitions in terms of Higgs-like bosons due to selection rules dictated by the quantum number ∑3 , the neutral Higgs-like bosons H0 (+1) and H0 (-1) can be found, for example, in the excesses, above SM values, of the decays t>u H0 (+1) and b>u H0 (-1) , which in terms of the quantum number ∑3 mean, respectively, +1 = 0 + (+1) and -1 = 0 + (-1). As for the charged Higgs-like boson H+ (+2), we should look for excesses in the decays t>b H+ (+2) and t>s H+ (+2), which mean  +1 = -1 + (+2) in terms of ∑3. And with the transition b>c H (-2) we could  also corroborate BaBar results. For more details take a look at other posts in this web page. It is important to have in mind that all Higgs decays seen up to now obey the selection rules  dictated by ∑ . Please, take a look at the post

Number of mass peaks for the Higgs-like bosons

As shown in the papers The Higgs-like Bosons and Quark Compositeness and The Higgs boson and quark compositeness  the Higgs-like bosons quantum numbers are given by the table

Boson 3
H0 0 ±1
H+, H  ±1 ±2

As it is clear from the calculation in the paper The Higgs-like Bosons and Quark Compositeness, H0+1 and H0-1 refer to particle and antiparticle, and thus, in terms of mass, H0+1 and H0-1 should have the same mass. Therefore, H0 has two masses. Following this reasoning we expect H++1 and H+-1 to have the same mass which should be equal to the mass of H+1 and H-1 , and thus these four bosons should have the same mass. The same should hold for H++2, H+-2, H+2 and H-2  that should have the same mass. Therefore, the eleven Higgs-like bosons should have four different masses. The number eleven comes from three H0, four H+ and four H–  and includes particles and antiparticles.

The bosons H+ and H  can be found from weak decays of heavy mesons such as the B mesons decays analyzed by the BaBar collaboration which reported an excess that points in the direction of charged Higgs-like bosons. For references, please take a look at the above paper The Higgs boson and quark compositeness  or go directly to

Solution to the Proton Spin Puzzle

As shown below the proton spin puzzle is just an important proof of quark compositeness. The proton spin puzzle started with the paper by the European Muon Collaboration (EMC) [Phys. Lett. B Vol. 206(2), 1988] which found for the proton spin the result  (1±12±24)% of the total spin. The solution is, actually, very simple and is […]

The Higgs Boson and Quark Compositeness

I am recreating this post that was erased somehow, I do not know how. Considering that each quark is composed of two prequarks, called primons, it is shown that the recently found neutral Higgs-like boson belongs to a triplet constituted of a neutral boson and two charged bosons and , and that is, actually, a […]

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.) […]

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 is wrong

The article Plot of the week – quark compositeness is nowhere near posted in Tommaso Dorigo’s blog is wrong. 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 of hadrons reveal compositeness of quarks, what CMS and ATLAS have found is that […]

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 […]

FALSE PROOF OF VALENCE QUARKS

  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 […]
