Nonperturbative transverse momentum broadening in dihadron angular correlations in $s_{N N} = 200$ GeV proton-nucleus collisions

C. Aidala, Y. Akiba, M. Alfred +296

The PHENIX collaboration has measured high- $p_{T}$ dihadron correlations in $p$ $+$ $p$ , $p$ $+$ Al, and $p$ $+$ Au collisions at $s_{_{N N}} = 200$ GeV. The correlations arise from in…
