Title : A Basis for the Standard Model as a Fundamental Theory
Abstract:
| For over 30 years most physicists have viewed the Standard Model as an inelegant approximation to a deeper, elegant theory of the forces and particles of Nature such as a Superstring Theory. In this seminar we will describe an extension of Lorentz transformations to include relative velocities greater than c, the corresponding extended Lorentz group of these transformations, and a canonical formulation of tachyon quantum field theory (which has been lacking since the pioneering attempts of Sudarshan and others in the 1960's). Tachyons exist in Black Holes (Schwarzschild solution) and in many Superstring theories. We then derive major features of the Standard Model based on invariance under this extended Lorenz group; minimal Yang-Mills couplings; and the identification of neutrinos, and one quark of each quark doublet, as tachyons. Derived features include the form of parity violation, the general form of the ElectroWeak sector (left-handed doublets and right-handed singlets), and quark confinement. The existence of 3 generations, mixing, and color SU(3) are not derived. Thus "inelegant" features of the Standard Model are shown to be derivable from invariance under subluminal and superluminal transformations, suggesting that the Standard Model may be fundamental and not an interim phenomenological theory. Even if the Standard Model is the low energy form of a more fundamental theory then that theory should also directly embody the above-mentioned derived features. |
