Still about induced spinor fields and TGD counterpart for HiggsThe understanding of the modified Dirac equation and of the possible classical counterpart of Higgs field in TGD framework is not completely satisfactory. The emergence of twistor lift of Kähler action inspired a fresh approach to the problem and it turned out that a very nice understanding of the situation emerges. More precise formulation of the Dirac equation for the induced spinor fields is the first challenge. The welldefinedness of em charge has turned out to be very powerful guideline in the understanding of the details of fermionic dynamics. Although induced spinor fields have also a part assignable spacetime interior, the spinor modes at string world sheets determine the fermionic dynamics in accordance with strong form of holography (SH). The welldefinedness of em charged is guaranteed if induced spinors are associated with 2D string world sheets with vanishing classical W boson fields. It turned out that an alternative manner to satisfy the condition is to assume that induced spinors at the boundaries of string world sheets are neutrinolike and that these string world sheets carry only classical W fields. Dirac action contains 4D interior term and 2D term assignable to string world sheets. Strong form of holography (SH) allows to interpret 4D spinor modes as continuations of those assignable to string world sheets so that spinors at 2D string world sheets determine quantum dynamics. Twistor lift combined with this picture allows to formulate the Dirac action in more detail. Welldefinedness of em charge implies that charged particles are associated with string world sheets assignable to the magnetic flux tubes assignable to homologically nontrivial geodesic sphere and neutrinos with those associated with homologically trivial geodesic sphere. This explains why neutrinos are so light and why dark energy density corresponds to neutrino mass scale, and provides also a new insight about color confinement. A further important result is that the formalism works only for imbedding space dimension D=8. This is due the fact that the number of vector components is the same as the number of spinor components of fixed chirality for D=8 and corresponds directly to the octonionic triality. pAdic thermodynamics predicts elementary particle masses in excellent accuracy without Higgs vacuum expectation: the problem is to understand fermionic Higgs couplings. The observation that CP_{2} part of the modified gamma matrices gives rise to a term mixing M^{4} chiralities contain derivative allows to understand the massproportionality of the Higgsfermion couplings at QFT limit.
