Description
To study the nature of collective phenomena in small collision systems, this contribution presents the measurement of the second harmonic of the anisotropic flow of heavy-flavor hadrons such as $D_0$ and $Λ^+_C$, also denoted as elliptic flow or $v_2$. The two-particle correlations method is used, where heavy-flavor candidates are correlated with hadrons.
Heavy-flavor candidates are reconstructed in the Time Projection Chamber
(TPC) of the ALICE detector and are correlated with hadrons from the forward region. This can be done thanks to the newest additions of the ALICE detector for Run 3, the Muon Forward Tracker (MFT) and the FV0 subsystem of the Fast Interaction Trigger.
Using hadrons from the forward region allows us to increase the ∆η gap in the two-dimensional correlation function to eliminate the near-side jet peak, and most of other non-flow contributions.
To do so, a newly developed “3x2PC” method using TPC-MFT, TPC-FV0 and
MFT-FV0 correlations will be used along with template fit to extract the $v_2$ coefficient.
The results presented will mostly focus on correlations with heavy-flavor candidates reconstructed in the TPC, and hadrons from the MFT in proton-proton collisions at √s = 13.6 TeV.
