Left: comparison of the $\pT$-differential $v_2^{\rm \mu} \lbrace {\rm 2P} \rbrace$ of inclusive muons at forward rapidity in high-multiplicity p--Pb collisions at $\sNN = 8.16$ \TeV with CGC-based calculations  The predictions are shown for muons from charm-hadron decays and beauty-hadron decays, separately, muons from charged-pion and kaon decays, and for muons from the combination of the various sources Right: comparison of the $\pT$-differential $v_2$ of muons from heavy-flavour hadron decays as obtained with CGC and AMPT calculations with the measured inclusive muon $v_2$.
