Abstract

A composite model of quarks and bosons is proposed in which a spin 1/21/2 isospin doublet ψ\psi is the basic building block of quarks and bosons in the standard model. The ψ\psi has two components vv and ww with charges Q=13eQ=\frac{1}{3}e and Q=0Q=0, respectively, that combine to form the three generations of colored quark flavors. A strong force described by a triplet of massless gluons bind the constituents called geminis. The confining constituent non-Abelian SU(2)CSU(2)_C field theory is called constituent dynamics with a confining energy scale ΛCD\Lambda_{CD}. The constituent dynamics condensate vˉv+wˉw0\langle\bar{v}v+\bar{w}w\rangle\neq 0 spontaneously breaks the electroweak symmetry SU(2)L×U(1)YU(1)EMSU(2)_L\times U(1)_Y\rightarrow U(1)_{\rm EM} and a triplet of Nambu-Goldstone bosons make the gauge bosons W±W^{\pm} and Z0Z^0 massive, while retaining a massless photon. A global custodial SU(2)L×SU(2)RSU(2)_L\times SU(2)_R symmetry guarantees that the symmetry breaking in the weak interaction sector agrees with electroweak data. The non-Abelian SU(2)CSU(2)_C color dynamics satisfies asymptotic freedom, which resolves the gauge and Higgs mass hierarchy problems and makes the model ultraviolet complete. The composite constituent dynamics model can realize a SU(3)C×SU(2)L×U(1)YSU(3)_C\times SU(2)_L\times U(1)_Y electroweak and strong interaction model that satisfies the naturalness principle. The three generations of colorless quarks α\alpha and β\beta with charges Q=+1eQ=+1e and Q=0Q=0, respectively, which are predicted to exist in the composite model can form bound states which can be identified with the spectrum of exotic mesons.
