It is not long time when an axion candidate from optiacl rotation experiments see . The mass of this axion was in millieV range so that there is a difference of 12 orders of magnitude as compared to this axion. This makes me wonder why the term neutral pseudoscalar particle is not used instead of axion : is the reason political?These two are not the only candidate for neutral pseudoscalars. I add here my comment to the blog of Lubos. The first evidence for pion/axion-like particles created in heavy-nucleus collisions near Coulomb threshold in MeV range came for more than 20 years ago. I developed a TGD based model for their strange production characteristics for more than 15 years ago.TGD explanation was based on what I called leptohadron physics with quarks replaced by color octet excitations of electrons allowed by TGD view about color. The production mechanism was creation of leptopions in strong non-orthogonal E and B with action given by E.B. Coupling to photons is dictated by partically conserved axial current hypothesis and identical with the coupling of pion/axion. The mass of the lowest leptopion state is very nearly to 2 times electron masses. Also heavier excitations on Regge trajectory are predicted: actually entire spectroscopy of leptomesons and leptobaryons. Exotic quarks with MeV mass scale and corresponding to Mersenne prime M_127=2^k-1, k=127, characterizing electron, play a key role in TGD based model of nuclei as string like structure with threads connecting nucleons having quark and antiquark at their ends. The model explains tetraneutron and predicts a new exotic states of nuclei.Quite generally, TGD predicts entire hierarchy of p-adically scaled up variants of standard model physics with mass scales coming as powers of half octaves. p=about 2^k. k prime or power of prime, are favored. Hence pionlike states should exist at various length scales and serve as a signature of various scaled variants of QCD like physics.*Mass scale 8 MeV (compare with 7 MeV) would correspond to k= 11^2, and thus power of prime.*Mass scale of 16 MeV (compare with 19 MeV) to p=about 119=7*17.Below a list of references about early evidence for pionlike states which people for some reason probably related to shortcomings of ancient theories( want to call axions. 1.
