We report on the rapidity and centrality dependence of proton and antiproton transverse mass distributions from $^{197}\mathrm{Au}+^{197}\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=130\phantom{\rule{0.3em}{0ex}}\mathrm{GeV}$ as measured by the STAR experiment at the Relativistic Heavy Ion Collider (RHIC). Our results are from the rapidity and transverse momentum range of $\ensuremath{\mid}y\ensuremath{\mid}<0.5$ and $0.35<{p}_{t}<1.00\phantom{\rule{0.3em}{0ex}}\mathrm{GeV}∕c$. For both protons …
