Radiative Corrections as the Origin of Spontaneous Symmetry Breaking
Erick J. Weinberg
Although old, this may be of interest. In particular, I have had inquiries concerning the renormalization group calculations in Sec. 6.4. This is a Latex transcription. A scanned v…
Duality and Massless Monopoles
Erick J. Weinberg
Duality arguments suggest the existence of massless magnetic monopoles in gauge theories with the symmetry broken to a non-Abelian subgroup. I discuss how these arise and show how…
Massive Monopoles and Massless Monopole Clouds
Erick J. Weinberg
Magnetic monopole solutions naturally arise in the context of spontaneously broken gauge theories. When the unbroken symmetry includes a non-Abelian subgroup, investigation of the…
Massive and Massless Monopoles and Duality
Erick J. Weinberg
I review some aspects of BPS magnetic monopoles and of electric-magnetic duality in theories with arbitrary gauge groups. When the symmetry is maximally broken to a U(1)^r subgroup…
Massless and Massive Monopoles Carrying Nonabelian Magnetic Charges
Erick J. Weinberg
The properties of BPS monopoles carrying nonabelian magnetic charges are investigated by following the behavior of the moduli space of solutions as the Higgs field is varied from a…
