Varying alpha, mass generation and extra dimensions
Thomas Dent
We consider variation of coupling strengths and mass ratios in and beyond the Standard Model, in the light of various mechanisms of mass generation. In four-dimensional unified mod…

CP from strings: ideas and problems
Thomas Dent
CP has a natural embedding in superstring models as a gauge symmetry involving inversion of the compactified space. Hence the source of CP violation could be geometrical. Such mode…

CP violation and target-space modular invariance
Thomas Dent
We show that, in perturbative string models where the source of CP violation is a complex vacuum expectation value (v.e.v.) for one or more compactification moduli, CP is conserved…
