Unpolarized cross section results are measured for transverse momenta $p_T$ = 0.5 to 7 GeV/$c$. Next-to-leading order perturbative quantum chromodynamics calculations are compared with the data, and while the calculations are consistent with the measurements, next-to-leading logarithmic corrections improve the agreement. Double helicity asymmetries ALL are presented for $p_T$ = 1 to 4 GeV/$c$ and probe the higher range of Bjorken $x$ of the gluon ($x_g$) with better statistical precision than our previous measurements at $\\sqrt{s}$ = 200 GeV. These measurements are sensitive to the gluon production in the proton for 0.06 < $x_g$ < 0.4.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.142076.v1/t1","@type":"Dataset","description":"The fraction of inclusive $\\pi^0$ yield which satisfied the BBC trigger condition.","name":"Figure 1"},{"@id":"https://doi.org/10.17182/hepdata.142076.v1/t2","@type":"Dataset","description":"The neutral pion production cross section at $\\sqrt{s}$ = 62.4 GeV as a function of $p_T$ and the results of...","name":"Figure 3"},{"@id":"https://doi.org/10.17182/hepdata.142076.v1/t3","@type":"Dataset","description":"The parameter $n$ obtained from the ratio of invariant cross section at $\\sqrt{s}$ = 62.4 GeV and $\\sqrt{s}$ = 200GeV,...","name":"Figure 4"},{"@id":"https://doi.org/10.17182/hepdata.142076.v1/t4","@type":"Dataset","description":"The double helicity asymmetry for neutral pion production at $\\sqrt{s}$ = 62.4 GeV as a function $p_T$ (GeV/$c$).
