Higgs Field as the Gauge Field Corresponding To Parity in the Usual Space-Time
(World Scientific Publishing Co. Pte Ltd, 1998) Erdem, Recai
We find that the local character of field theory requires the parity degree of freedom of the fields to be considered as an additional discrete fifth dimension which is an artifact emerging due to the local description of space-time. Higgs field can be interpreted as the gauge field corresponding to this discrete dimension. Hence the noncommutative geometric derivation of the standard model follows as a manifestation of the local description of the usual space-time.
1/Nc Expansion and Anomaly Cancellation in the Presence of Electroweak Interactions
(IOP Publishing Ltd., 1998) Erdem, Recai
We study the question of a consistent formulation of the 1/Nc expansion in the presence of electroweak interactions. We show that in some cases the previous formulation leads to an unrealistic picture. We improve the scheme. We derive the corresponding hypercharge and electric charge values of fermions under the requirement that the standard model in the large-Nc limit should be free of chiral gauge anomalies. We find that the resulting hypercharge and the electric charge values for quarks are the same as for the standard model.
