Abstract: We consider Quantum Electrodynamics in 2 + 1 dimensions with N f fermionic or bosonic flavors, allowing for interactions that respect the global symmetry U( N f /2) 2 . There are four bosonic and four fermionic fixed points, which we analyze using the large N f expansion. We systematically compute, at order O (1/ N f ), the scaling dimensions of quadratic and quartic mesonic operators.
