Query: The Fermionic Universal One-Loop Effective Action   Recent development of path integral matching techniques based on the
covariant derivative expansion has made manifest a universal structure of
one-loop effective Lagrangians. The universal terms can be computed once and
for all to serve as a reference for one-loop matching calculations and to ease
their automation. Here we present the fermionic universal one-loop effective
action (UOLEA), resulting from integrating out heavy fermions with scalar,
pseudo-scalar, vector and axial-vector couplings. We also clarify the relation
of the new terms computed here to terms previously computed in the literature
and those that remain to complete the UOLEA. Our results can be readily used to
efficiently obtain analytical expressions for effective operators arising from
heavy fermion loops.
