Determination of SU(4)TC Technicolor Gauge Group from Embedding in Extended Technicolor

الأصل · EN

In technicolor theories using an SU(NTC) gauge group, the value of NTC is not, a priori, determined and is typically chosen by phenomenological criteria. Here we present a novel way to determine NTC from the embedding of a one-family technicolor model, with fermions in the fundamental represention of SU(NTC), in an extended technicolor theory, and use it to deduce that NTC=4 in this framework.
