New perspectives in physics beyond the standard model

摘要

In 1934 Fermi postulated a theory for weak interactions containing a dimensionfulcoupling with a size of roughly 250GeV. Only now are we finally exploring this energy regime. What arises is an open question: supersymmetry and large extra dimensions are two possible scenarios. Meanwhile, other experiments will begin providing definitive information into the nature of neutrino masses and CP violation. In this paper, we explore features of possible theoretical scenarios, and study the phenomenological implications of various models addressing the open questions surrounding these issues.
