We suggest that certain discrete chiral symmetries, which are remnant of axial U(1) symmetries of a more fundamental theory, may explain the origin of the relation, $\tan \theta_C \simeq \sqrt m_d / m_s$. Simple models illustrating this idea are constructed in which quarks and standard techniquarks appear as composite states made of a more fundamental set of fermions.

Abstract
We suggest that certain discrete chiral symmetries, which are remnant of axial U(1) symmetries of a more fundamental theory, may explain the origin of the relation, $\tan \theta_C \simeq \sqrt m_d / m_s$. Simple models illustrating this idea are constructed in which quarks and standard techniquarks appear as composite states made of a more fundamental set of fermions.File in questo prodotto:
