Toward solving the cosmological constant problem by embedding
Roman V. Buniy, Thomas W. Kephart
The typical scalar field theory has a cosmological constant problem. We propose a generic mechanism by which this problem is avoided at tree level by embedding the theory into a la…
Natural fermion mass hierarchy and mixings in family unification
James B. Dent, Robert Feger, Thomas W. Kephart +1
We present an SU(9) model of family unification with three light chiral families, and a natural hierarchy of charged fermion masses and mixings. The existence of singlet right hand…
Towards Realizing Warm Inflation in String Theory
Mar Bastero-Gil, Arjun Berera, James B. Dent +1
We give a generic argument that string theory provides a natural setting for warm inflationary cosmology. We then explore a specific model with an inflaton modulus field coupled to…
Fermion Mixings in SU(9) Family Unification
Paul H. Frampton, Thomas W. Kephart
In an SU(9) model of gauged family unification, we propose an explanation for why angles observed in the lepton flavor ({\it PMNS}) mixing matrix are significantly larger than thos…
A Note on Embedding Nonabelian Finite Flavor Groups in Continuous Groups
Paul H. Frampton, Thomas W. Kephart, Ryan M. Rohm
A nonabelian finite flavor group can have double covering such that . This situation is not contradictory, but quite na…
