We consider two identical fermions interacting in the p-wave channel. Each fermion also interacts with another particle in the vicinity of an s-wave resonance. We find that in addition to the Kartavtsev-Malykh universal trimer states resulting from the s-wave particle-fermion interaction, the fermion-fermion p-wave interaction induces one or two shallow trimers in a large domain of the control parameters, including a borromean regime where the ground-state trimer exists in the absence of dimers at any mass ratio between the fermions and the particle. A generic picture of the trimer spectrum emerges from this work in terms of the low-energy parameters of the interactions.

Reports on this Submission
The authors have satisfactorily answered all of my comments. I particularly applaud the authors' significantly enhanced discussion of how they arrive at their main equations, including a new Appendix, as well as the new section on the potential for experimental observation. I am therefore happy to recommend publication in SciPost Physics.
There is a typo in "Schrödinger" at the bottom of page 17, first column.
