We construct a model in which stable magnetic monopoles have magnetic charges that are identical to the electric charges on leptons and quarks and the colored monopoles are confined by strings in color

We have investigated Bc spectroscopy with the use of a quantumchromodynamic potential model which was recently used by us for the lightheavy quarkonia. We give our predictions for the energy levels and the E1 transition widths. We also find, rather surprisingly, that although Bc is not a light-heavy system, the heavy quark effective theory with the inclusion of the m b and m −1 b lnmb correctio...

These five lectures give an elementary introduction to perturbative superstring theory, superstring phenomenology, and the fermionic construction of perturbative string models. These lectures assume no prior knowledge of string theory.
