E. Antonyan, J. A. Harvey, D. Kutasov
TL;DR
This paper investigates how intersecting D-brane models can lead to dynamical chiral symmetry breaking and fermion mass generation through bulk field interactions, depending on brane configurations.
Contribution
It provides a detailed analysis of conditions under which dynamical symmetry breaking occurs in intersecting D-brane models, highlighting the role of brane and intersection dimensions.
Findings
Certain brane configurations induce fermion mass generation.
Interactions via bulk fields can lead to chiral symmetry breaking.
The conditions depend on the dimensions of branes and intersections.
Abstract
We study a class of intersecting D-brane models in which fermions localized at different intersections interact via exchange of bulk fields. In some cases these interactions lead to dynamical symmetry breaking and generate a mass for the fermions. We analyze the conditions under which this happens as one varies the dimensions of the branes and of the intersections.
