Gauge Hierarchy

Abstract

The chirality is the key for our world. In this scheme, I present a solution of the long standing gauge hierarchy problem with a hidden sector SU(5)${}^{\prime }$ with representations $\overline{10}\oplus \overline{5}\oplus 2\cdot 5$. Sideway remarks are on {\it NATURAL HILLTOP} inflation and a bound on the QCD angle $\bar{\theta }$.
