Abstract: (arXiv)

We report on the measurement of inclusive, non-prompt, and prompt J/

\psi

-hadron correlations by the ALICE Collaboration at the CERN Large Hadron Collider in pp collisions at a center-of-mass energy of 13 TeV. The correlations are studied at midrapidity (

|y| < 0.9

) in the transverse momentum ranges

p_{\rm T} < 40~\text{GeV}/c

for the J/

\psi

and

0.15 < p_{\rm T} < 10

GeV/

c

and

|\eta|<0.9

for the associated hadrons. The measurement is based on minimum bias and high multiplicity data samples corresponding to integrated luminosities of

L_{\text{int}} = 34~\text{nb}^{-1}

and

L_{\text{int}} = 6.9~\text{pb}^{-1}

, respectively. In addition, two more data samples are employed, requiring, on top of the minimum bias condition, a threshold on the tower energy of

E = 4

and

9~\text{GeV}

in the ALICE electromagnetic calorimeters, which correspond to integrated luminosities of

L_{\text{int}} = 0.9~\text{pb}^{-1}

and

L_{\text{int}} = 8.4~\text{pb}^{-1}

, respectively. The results are presented as associated hadron yields per J/

\psi

trigger as a function of the azimuthal angle difference between the associated hadrons and J/

\psi

mesons. The integrated near-side and away-side correlated yields are also extracted as a function of the J/

\psi

transverse momentum. The measurements are discussed in comparison to PYTHIA calculations.
