Gauge Hierarchy


Abstract in English

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)$$ with representations $overline{bf 10}oplus overline{bf 5}oplus 2cdot{bf 5}$. Sideway remarks are on {it NATURAL HILLTOP} inflation and a bound on the QCD angle $bartheta$.
