摘要: The infrared dynamics of 2 + 1 dimensional quantum electrodynamics (QED3) with a large number N fermion flavors is governed by an interacting CFT that can be studied in the 1/N expansion. We use expansion to calculate scaling dimensions all lowest three scalar operators transform under SU(N ) flavor symmetry as Young diagram two columns not necessarily equal heights and have vanishing topological charge. In case singlets, we study mixing $$ \left({\overline{\psi}}_i{\psi}^i\right)\left({\overline{\psi}}_j{\psi}^j\right) $$ F μν , which are dimension parity-even singlets. Our results suggest these irrelevant for > 1.
