(Chart from the paper The Higgs boson and quark compositeness published in Moriond 2014 proceedings)
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 ∑3 . Please, take a look at the post
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.

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 […]
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 […]
