Abstract:

Attempts to account for the elementary properties of matter through a structure of extra spatial dimensions date from the theory of Kaluza 100 years ago. In more recent years, while there is still no clear evidence that extra dimensions of space exist, the origin of the structure of the Standard Model has become a central question in fundamental particle physics. We motivate a new approach with a further generalisation from the local 4-dimensional spacetime geometry to a general form for proper time. This approach will be shown to lead directly and efficiently to Standard Model structures and areas of new physics beyond. As an additional feature of the theory a natural candidate for dark matter, itself a further major mystery in physics, can also be directly identified. The possibility of accounting for all three sectors of the 'cosmological pie chart', including a connection with dark energy models, within this unifying framework will be described.
