Fermionic Bound States and Pseudoscalar Exchange
A Anselm, N Dombey
Abstract
We discuss the possibility that fermions bind due to Higgs or pseudoscalar exchange. It is reasonable to believe on qualitative grounds that this can occur for fermions with a mass larger than 800-900 GeV. An exchange of a pseudoscalar boson leads in the non-relativistic limit to an unacceptable potential which behaves like 1/r3 at the origin. We show that this singular behaviour is smeared out when relativistic effects are included.
