The Origin of mass
- Physics
- 2003
The quark–lepton mass problem and the ideas of mass protection are reviewed. The hierarchy problem and suggestions for its resolution, including Little Higgs models, are discussed. The Multiple Point…
Quark mass matrices in superstring models
- Physics
- 1997
Four simple but realistic patterns of quark mass matrices are derived from orbifold models of superstring theory in the absence of gauge symmetries. Two of them correspond to the Ramond–Roberts–Ross…
Tests of non-standard electroweak couplings of right-handed quarks
- Physics
- 2008
The standard model can be interpreted as the leading order of a Low-Energy Effective Theory (LEET) invariant under a higher non linearly realized symmetry Snat ⊃ SU(2)W × U(1)Y equipped with a…

Are there quasistable hadrons containing superheavy quarks
- Physics
- 1977
Flavor-changing neutral currents are reconsidered allowing the possibility that superheavy quarks, with masses comparable to the weak-boson mass, exist in nature. It is argued that the natural…
Electromagnetic and weak masses
- Physics
- 1972
In theories with spontaneously broken gauge symmetries, various masses, or mass differences may vanish in zeroth order as a consequence of the representation content of the fields appearing in the…
Approximate symmetries and pseudo-goldstone bosons
- Physics
- 1972
In theories with spontaneously broken local symmetries, renormalizability sometimes forces the scalar field interactions to have a larger group of symmetries than the gauge field interactions.…
Unity of All Elementary Particle Forces
- Physics
- 1974
Strong, electromagnetic, and weak forces are conjectured to arise from a single fundamental interaction based on the gauge group SU(5).
