Using bosonization-fermionization transformation we map theTomonaga-Luttinger model of spinless fermions with non-linear dispersion on themodel of fermionic quasiparticles whose interaction is irrelevant in therenormalization group sense. Such mapping allows us to set up an expansion forthe density-density propagator of the original Tomonaga-Luttinger Hamiltonianin orders of the (irrelevant) quasiparticle interaction. The lowest order termin such an expansion is proportional to the propagator for free fermions. Thenext term is also evaluated. The propagator found is used for calculation ofthe Coulomb drug resistivity $r$ in a system of two capacitively coupledone-dimensional conductors. It is shown that $r$ is proportional to $T^2$ forboth free and interacting fermions. The marginal repulsive in-chain interactionacts to reduce $r$ as compared to the non-interacting result. The correction to$r$ due to the quasiparticle interaction is found as well. It scales as $T^4$at low temperature.
