Understanding nature with the spin-charge-family theory

More than 50 years ago the standard model made a successful new step in understanding properties of fermion and boson fields. Now the next step is needed, which would explain what the standard model and the cosmological models just assume: a. The origin of quantum numbers of massless one family members – quarks and leptons and anti-quarks and antileptons. b. The origin of families. c. The origin of the vector gauge fields coupled to quarks and leptons. d. The origin of the Higgs and Yukawa couplings and correspondingly of the masses of quarks and leptons. e. The origin of the dark matter. f. The origin of the matter-antimatter asymmetry in our universe. g. The explanation for the postulates of the second quantized fermion fields. h. And several other open problems. I am proposing the spin-charge-family theory, a kind of the Kaluza-Klein theories in (d=(2n-1) +1)-spacetime, with d=(13+1) and the two kinds of the spin connection fields, which are the (gravitational) gauge fields of the two kinds of the Clifford algebra objects anti-commuting with one another, promising to provide this much needed next step. The talk presents: i. A short overview of this theory and the achievements of this theory so far, pointing out new ideas. ii. The explanation for the Dirac postulates for the second quantization of the fermion fields. iii. Predictions for future experiments. The more effort is put into this theory the more solutions to the open problems in both standard models the theory offers.
