Families from Supergroups and Predictions for Leptonic CP Violation
S. M. Barr, Heng-Yu Chen
As was shown in 1984 by Caneschi, Farrar, and Schwimmer, decomposing representations of the supergroup SU(M|N), can give interesting anomaly-free sets of fermion representations of…
A Model of Quark and Lepton Mixing and Mass Hierarchy
S. M. Barr, Heng-Yu Chen
It is shown that an idea proposed in 1996 that relates in a qualitatively correct way the inter-family mass hierarchies of the up quarks, down quarks, charged leptons, and neutrino…
Infinite Classes of Cases with Non-trivial Anomaly Cancellation
S. M. Barr
It is pointed out that there are infinite classes of cases based on gauge groups of the form SU(p)xSU(q)xU(1) in which gauge anomalies cancel non-trivially for small sets of fermio…
New confining force solution of QCD axion domain wall problem
S. M. Barr, Jihn E. Kim
The serious cosmological problems created by the axion-string/axion-domain-wall system in standard axion models are alleviated by positing the existence of a new confining force. T…
Absolutely Stable Proton and Lowering the Gauge Unification Scale
S. M. Barr, X. Calmet
A unified model is constructed, based on flipped in which the proton is absolutely stable. The model requires the existence of new leptons with masses of order the weak sca…
Cogeneration of Dark Matter and Baryons by Non-Standard-Model Sphalerons in Unified Models
S. M. Barr, Heng-Yu Chen
Sphalerons of a new gauge interaction can convert a primordial asymmetry in B or L into a dark matter asymmetry. From the equilibrium conditions for the sphalerons of both the elec…
