Deuteron production in high-energy collisions is sensitive to the space–time evolution of the collision system, and is typically described by a coalescence mechanism. For the first time, we present results on jet-associated deuteron production in pp collisions at √s=13 TeV, providing an opportunity to test the established picture for deuteron production in events with a hard scattering. Using a trigger particle with high transverse-momentum (pT>5 GeV/c) as a proxy for the presence of a jet at midrapidity, we observe a measurable population of deuterons being produced around the jet proxy. The associated deuteron yield measured in a narrow angular range around the trigger particle differs by 2.4–4.8 standard deviations from the uncorrelated background. The data are described by PYTHIA model calculations featuring baryon coalescence.

Multiplicity dependence of (anti-)deuteron production in pp collisions at √s = 7 TeV
ALICE Collaboration (Elsevier B.V., 2019)In this letter, the production of deuterons and anti-deuterons in pp collisions at √s = 7 TeV is studied as a function of the charged-particle multiplicity density at mid-rapidity with the ALICE detector at the LHC. ... -
(Anti-)deuteron production in pp collisions at √s = 13 TeV
ALICE Collaboration (Springer, 2020)The study of (anti-)deuteron production in pp collisions has proven to be a powerful tool to investigate the formation mechanism of loosely bound states in high-energy hadronic collisions. In this paper the production of ... -
Centrality-Dependent Modification of Jet-Production Rates in Deuteron-Gold Collisions at √sNN = 200 GeV
PHENIX Collaboration (American Physical Society, 2016)Jet production rates are measured in p þ p and d þ Au collisions at √sNN = 200 GeV recorded in 2008 with the PHENIX detector at the Relativistic Heavy Ion Collider. Jets are reconstructed using the R ¼ 0.3 anti-kt ... -
