Higher order curvature generalisations of Bartnick-McKinnon and coloured black hole solutions in
Yves Brihaye, A. Chakrabarti, Betti Hartmann +1
We construct globally regular as well as non-abelian black hole solutions of a higher order curvature Einstein-Yang-Mills (EYM) model in dimensions. This model consists of th…
An extended model for monopole catalysis of nucleon decay
Y. Brihaye, D. Yu. Grigoriev, V. A. Rubakov +1
A new model for monopole catalysis of nucleon decay is proposed. Unlike in the earlier one, the only light fields in this model are the photon and Skyrme (pion) field. The model ad…
Quasi exactly solvable operators and Lie superalgebras
Yves Brihaye, Betti Hartmann
Linear operators preserving the direct sum of polynomial rings P(m)\oplus P(n) are constructed. In the case |m-n|=1 they correspond to atypical representations of the superalgebra…
Interaction of global and local monopoles
Eugenio R. Bezerra de Mello, Yves Brihaye, Betti Hartmann
We study the direct interaction between global and local monopoles. While in two previous papers, the coupling between the two sectors was only indirect through the coupling to gra…
