String/M theory
C. P. Bachas
This is a brief review of the present status, of some recent developments and of the open challenges in string/M theory.
Unification with Low String Scale
Constantin P. Bachas
I argue that in open-string theory with hierarchically small (or large) extra dimensions, gauge groups can unify naturally with logarithmically-running coupling constants at the hi…
New String Excitations in the Two-Higgs Standard Model
C. Bachas, B. Rai, T. N. Tomaras
We establish the existence of a static, classically stable string solution in a region of parameters of the generic two-Higgs Standard Model. In an appropriate limit of parameters,…
On Spherically-Symmetric Solutions in the Two-Higgs Standard Model
C. Bachas, P. Tinyakov, T. N. Tomaras
We report the results of a numerical search for non-topological solitons in the two-Higgs standard model, characterized by the non-trivial winding, , of the relative phas…
Membranes in the two-Higgs standard model
C. Bachas, T. N. Tomaras
We present some non-topological static wall solutions in two-Higgs extensions of the standard model. They are classically stable in a large region of parameter space, compatible wi…
Are there solitons in the two-higgs standard model?
C. P. Bachas, T. N. Tomaras
We present some evidence, based on the analysis of lower-dimensional models, for the possible existence of classically-stable winding solitons in the two-higgs electroweak theory.
