Abstract: We study $pK^-$ scattering in the energy range from threshold through the$\Lambda1520$ peak in UBChPT, taking into account $\mathcal{O}q$ verticesfrom meson-baryon contact interactions and $s$- and $u$-channel ground-statebaryon exchange, $s$- and $u$-channel decuplet- and nonet-baryon exchange and$t$-channel vector-meson exchange, as well as $\mathcal{O}q^2$flavor-breaking vertices. Detailed fits to data are presented, including asubstantial body of differential cross-section data with meson momentum$q \mathrm{lab} > 300$ MeV not considered in previous treatments.
