Amending the Standard Model of Particle Physics

Some of my earlier arguments, suggesting modifications of the Standard Model of Particle Physics (see ref. 1), are elaborated and extended. Rules deduced from the known properties of elementary fermionsare sharpened and extended in the first part. Conclusions drawn from the rules in the second part are also honedand expanded and an estimate of the neutrino mass eigenstates is added. In the third part, a tentative explanation of the rules is discussed. In my earlier paper, I suggested replacing the point-sources postulated by the Standard Model for each generation by finite 'source-shapes', equal for all elementary fermionsof a generation and systematically decreasing in volume from the first to the third generation, thus increasing the effect of self-interactions. According to the rules a correlation exists between the mass of an elementary fermionand the strength of its self-interaction, thus an increase in self-interactions would resolve the problem of the hierarchical masses. A possible connection between the existence of only three generations and the three-dimensionality of space also is discussed. In the epilogue the question is explored whether finite source-shapes for the elementary fermionscan be reconciled with fundamental theoretical tenets.
