Inspired by the success of covariant baryon chiral perturbation theory in the one baryon sector and in the heavy-light systems, we explore the relevance of relativistic effects in the construction of the strangeness $S=-1$ hyperon-nucleon interaction using chiral perturbation theory. Due to the non-perturbative nature of the hyperon-nucleon interaction, we follow the covariant Weinberg's approach recently proposed by Epelbaum and Gegelia to sum the leading order chiral potential using the… CONTINUE READING
