In this work we study braneworld models in generalized $f\left(R,T\right)$gravity theories where the action depends on a function of the Ricci scalar $R$and the trace of the stress-energy tensor $T$. We explore the so-calledscalar-tensor representation of the theory, where the dependence on $R$ and $T$are exchanged for two auxiliary real scalar fields. We introduce a first-orderformalism to relate the auxiliary fields with the source field of brane andanalyze four distinct possibilities of current interest regardingcompactification and asymmetry of the brane. We investigate the behavior of theauxiliary fields and their stability in each one of the four cases. For themodels where the solution of the source field engenders compact behavior, theauxiliary fields exhibit a hybrid structure, behaving differently inside andoutside the compact region described by the source configuration. Inparticular, we found that the solutions of the auxiliary fields aresignificantly modified in models where the geometry is strongly influenced bythe source field. Moreover, for the model capable of engendering asymmetricfeatures, the two auxiliary fields also respond to modifications on theparameter that controls the asymmetry of the system.
