Query: Methods for separation of deuterons produced in the medium and in jets
  in high energy collisions   Coalescence has long been used to describe the production of light
(anti-)nuclei in heavy ion collisions. The same underlying mechanism may also
exist in jets when a proton and a neutron are close enough in phase space to
form a deuteron. We model deuteron production in jets by applying an
afterburner to protons and neutrons produced in PYTHIA for $p$+$p$ collisions
at a center of mass energy $\sqrt{s} =$ 7 TeV. PYTHIA provides a reasonable
description of the proton spectra and the shape of the deuteron spectrum
predicted by the afterburner is in agreement with the data. We show that the
rise in the coalescence parameter $B_2$ with momentum observed in data is
consistent with coalescence in jets. We show that di-hadron correlations can be
used to separate the contributions from the jet and the underlying event. This
model predicts that the conditional coalescence parameter in the jet-like
correlation should be independent of the trigger momentum.
