This is the only measurement of the proton-proton elastic cross section in this $t$ range for collision energies above the Intersecting Storage Rings (ISR) and below the Large Hadron Collider (LHC) colliders.We find that a constant slope $B$ does not fit the data in the aforementioned $t$ range, and we obtain a much better fit using a second-order polynomial for $B(t)$. This is the first measurement below the LHC energies for which the non-constant behavior $B(t)$ is observed. The $t$ dependence of $B$ is determined using six subintervals of $t$ in the STAR measured $t$ range, and is in good agreement with the phenomenological models. The measured elastic differential cross section $\\mathrm{d}\\sigma/\\mathrm{dt}$ agrees well with the results obtained at $\\sqrt{s} = 540$ GeV for proton--antiproton collisions by the UA4 experiment. We also determine that the integrated elastic cross section within the STAR $t$-range is $\\sigma^\\mathrm{fid}_\\mathrm{el} = 462.1 \\pm 0.9 (\\mathrm{stat.}) \\pm 1.1 (\\mathrm {syst.}) \\pm 11.6 (\\mathrm {scale})$ $\\mu\\mathrm{b}$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.144920.v1/t1","@type":"Dataset","description":"Top panel: The $pp$ elastic differential cross section $d\\sigma/dt$ fitted with an exponential $A e^{-B(t)|t|}$.
