  "abstract": "This work applies a recent theoretical treatment of spin-dependent potentials to experimental searches, in particular in antiprotonic helium. The considered spin-dependent potentials between fermions or spin-polarised macroscopic objects result from an exchange of exotic spin-0 or spin-1 bosons. We address a superficial singularity in one of the potentials, as well as technical issues with contact terms, and use the results to obtain a bound on the pseudovector coupling constants and boson masses.",
