Non-factorisable metrics and Gauss--Bonnet terms in higher dimensions
B. Abdesselam, A. Chakrabarti, J. Rizos +1
An iterative construction of higher order Einstein tensors for a maximally Gauss-Bonnet extended gravitational Lagrangian was introduced in a previous paper. Here the formalism is…
A simplified model for monopole catalysis of nucleon decay
Y. Brihaye, V. A. Rubakov, D. H. Tchrakian +1
We present a simple model where a nucleon is treated as the Skyrmion, both monopole and Skyrmion are smooth solutions of the classical field equations,the baryon number non-conserv…
Antisymmetrised 2p-forms generalising curvature 2-forms II: a p-hierarchy of Reissner-Nordstrom type metrics in dimensions d>2p+1
A. Chakrabarti, D. H. Tchrakian
The p-hierarchy of Schwarzschild type metrics obtained in a preceing paper is generalised here to a corresponding Reissner-Nordstrom (RN) type hierarchy in the presence of a point…
Antisymmetrised 2p-forms generalising curvature 2-forms and a corresponding p-hierarchy of Schwarzschild type metrics in dimensions d>2p+1
A. Chakrabarti, D. H. Tchrakian
Starting with the curvature 2-form a recursive construction of totally antisymmetrised 2p-forms is introduced, to which we refer as p-Riemann tensors. Contraction of indices permit…
