Up and down quark mass hierarchy in an invisible axion model
Abstract
We study an invisible axion model in which the Higgs particles consist of only one isodoublet, one isosinglet and a pair of colortriplets. At the tree level only the up-type quarks obtain masses. The down-type quark masses result from one-loop radiative correction. We also discuss some of the related phenomenology.
