At the soft scale, charged particle production in low-EA p+Au collisions is comparable to that in p+p collisions and increases monotonically with increasing EA. At the hard scale, we report measurements of high transverse momentum (pT) jets in events of different EAs. In contrast with the soft particle production, high-pT particle production and EA are found to be inversely related. To investigate whether this is a signal of jet quenching in high-EA events, we also report ratios of pT imbalance and azimuthal separation of dijets in high- and low-EA events. Within our measurement precision, no significant differences are observed, disfavoring the presence of jet quenching in the highest 30% EA p+Au collisions at $\\sqrt{s_\\mathrm{NN}}$ = 200 GeV.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.151385.v1/t1","@type":"Dataset","description":"Distributions of Event Activity (as measured by the BBC) from MB and HT events with the latter satisfying an offline...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.151385.v1/t2","@type":"Dataset","description":"Density of charged particles with $p_\\mathrm{T}>0.2$ GeV/$c$ and $|\\eta|\\le0.9$ in ten ranges of EA for MB events and HT events...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.151385.v1/t3","@type":"Dataset","description":"Charged particle density as a function of EA, UE $\\eta$, and $p_\\mathrm{T,jet}^\\mathrm{lead}$ for HT ($E_\\mathrm{T}^\\mathrm{trig}>4$ GeV) events with $p_\\mathrm{T,jet}^\\mathrm{raw,lead}>4~\\mathrm{GeV}/c$.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.151385.v1/t4","@type":"Dataset","description":"Normalized distributions of EA in HT ($E_\\mathrm{T}^\\mathrm{trig}>4$ GeV) events selected by three ranges of leading jet $p_\\mathrm{T}$.
