A new determination of $\alpha_s$ using direct photon production cross sections in $pp$ and $\overline{p}p$ collisions at $\sqrt{s}=24.3$ GeV

Direct photon production cross sections obtained in high statistics $\bar{p}p$ and $pp$ collisions at $\sqrt{s}=24.3$ GeV at the CERN SPS are used in a next-to-leading order QCD analysis. From the ( stat.)~\pm0.0033\,(syst.)~^{+0.0077}_{-0.0034} \,(t cross section difference $\sigma(\bar{p}p~\to~\ga...
