Abstract

We present the first measurements of the forward and midrapidity $η$ -meson cross sections from $p + p$ collisions at $\sqrt{s} = 500$ and 510 GeV, respectively. We also report the midrapidity $η / π^{0}$ ratio at 510 GeV. The forward cross section is measured differentially in $η$ -meson transverse momentum ( $p_{T}$ ) from 1.0 to $6.5 GeV / c$ for pseudorapidity $3.0 < | η | < 3.8$ . The midrapidity cross section is measured from 3.5 to $44 GeV / c$ for pseudorapidity $| η | < 0.35$ . Both cross sections serve as critical inputs to an updated global analysis of the $η$ -meson fragmentation functions.
