Abstract

ATLAS measured the centrality dependence of the dijet yield using 165 nb⁻¹ of 𝑝+Pb data collected at √𝑠_NN =8.16 TeV in 2016. The event centrality, which reflects the 𝑝 +Pb impact parameter, is characterized by the total transverse energy registered in the Pb-going side of the forward calorimeter. The central-to-peripheral ratio of the scaled dijet yields, 𝑅_CP, is evaluated, and the results are presented as a function of variables that reflect the kinematics of the initial hard parton scattering process. The 𝑅_CP shows a scaling with the Bjorken 𝑥 of the parton originating from the proton, 𝑥_𝑝, while no such trend is observed as a function of 𝑥_Pb. This analysis provides unique input to understanding the role of small proton spatial configurations in 𝑝 +Pb collisions by covering parton momentum fractions from the valence region down to 𝑥_𝑝 ∼10⁻³ and 𝑥_Pb ∼4 ×10⁻⁴.

N2 - ATLAS measured the centrality dependence of the dijet yield using 165 nb−1 of 𝑝+Pb data collected at √𝑠NN =8.16 TeV in 2016. The event centrality, which reflects the 𝑝 +Pb impact parameter, is characterized by the total transverse energy registered in the Pb-going side of the forward calorimeter. The central-to-peripheral ratio of the scaled dijet yields, 𝑅CP, is evaluated, and the results are presented as a function of variables that reflect the kinematics of the initial hard parton scattering process. The 𝑅CP shows a scaling with the Bjorken 𝑥 of the parton originating from the proton, 𝑥𝑝, while no such trend is observed as a function of 𝑥Pb. This analysis provides unique input to understanding the role of small proton spatial configurations in 𝑝 +Pb collisions by covering parton momentum fractions from the valence region down to 𝑥𝑝 ∼10−3 and 𝑥Pb ∼4 ×10−4.
