Einstein-Yang-Mills-Dirac-Higgs theory

Idea

The theory in physics which describes the fundamental physics of the observable universe to best present knowledge is a local Lagrangian field theory which combines

theory:	Einstein-	Maxwell-	Yang-Mills-	Dirac-	Higgs
	gravity	electromagnetism	electroweak and strong nuclear force	fermionic matter	scalar field
fields	vielbein field $e$	$U(1)$-principal connection $\nabla_{em}$	$G$-principal connection	spinor $\psi$	scalar field $H$
Lagrangian $L =$	$R(e) vol(e) +$		$F_{\nabla_{}} \wedge \star_e F_{\nabla_{}} +$	$(\psi , D \psi) vol(e) +$	$\nabla \bar H \wedge \star_e \nabla H + \left(\lambda {\vert H\vert}^4 - \mu^2 {\vert H\vert}^2 \right) vol(e)$
