Enriching the Standard Model:

Following the suggestion of Friedberg-Lee, we introduce an extended family of sextuplet CP-even and triplet CP-odd Higgs fields that couple to the 3 generations of quarks. The Lagrangian is itself CP-conserving. But as a result of the spontaneous symmetry breaking of the Higgs potential, CP is broken. This extension of the Standard Model leads to observable CP oscillations at the LHC. Work in this direction is in progress.

Preliminary results were reported at the 1st IAS- Winter School on Particle Physics, Cosmology, and Implications for Technology, NTU, 9 - 31 January, 2012 ( http://www.ntu.edu.sg/ias/upcomingevents/iassppcit/Pages/LectureNotes.aspx )


Tritium beta decay experiments hint at tachyonic mass for electron neutrinos.
(http://www.physik.uni-mainz.de/exakt/neutrino/en_experiment.html )

Is there a consistent field theory for such faster-than-light neutrinos ? The answer is yes
( http://arxiv.org/abs/hep-ph/0105153 Modern Phys Letters A 16, 2129 (2001) )

How does a tachyonic mass affect the endpoint of tritium β-decay ?
See http://arxiv.org/abs/hep-ph/0410175 for a complete field-theoretic treatment of the decay spectrum, including the complex energy modes of the tachyon pole.
