There is quite a recent article entitled "Study of the Dependence of Direct Soft Photon Production on the Jet Characteristics in Hadronic Z0 Decays" discussing one particular manifestation of an anomaly of hadron physics known for two decades: the soft photon production rate in hadronic reactions is by an averge factor of about four higher than expected. In the article soft photons assignable to the decays of Z0 to quark-antiquark pairs. This anomaly has not reached the attention of particle physics which seems to be the fate of anomalies quite generally nowadays: large extra dimensions and blackholes at LHC are much more sexy topics of study than the anomalies about which both existing and speculative theories must remain silent.
TGD leads to an explanation of anomaly in terms of the basic differences between TGD and QCD.
The first difference is due to induced gauge field concept: both classical color gauge fields and the U(1) part of electromagnetic field are proportional to induced Kähler form. Second difference is topological field quantization meaning that electric and magnetic fluxes are associated with flux tubes. Taken together this means that for neutral hadrons color flux tubes and electric flux tubes can be and will be assumed to be one and same thing. In the case of charged hadrons the em flux tubes must connect different hadrons: this is essential for understanding why neutral hadrons seem to contribute much more effectively to the brehmstrahlung than charged hadrons- which is just the opposite for the prediction of hadronic inner bremsstrahlung model in which only charged hadrons contribute. Now all both sea and valence quarks of neutral hadrons contribute but in the case of charged hadrons only valence quarks do so.
Sea quarks of neutral hadrons seem to give the largest contribution to bremsstrahlung. p-Adic length scale hypothesis predicting that quarks can appear in several mass scales represents the third difference and the experimental findings suggest that sea quarks are by a factor of 1/2 lighter than valence quarks implying that brehmstrahlung for given sea quark is by a factor 4 more intense than for corresponding valence quark.
