# Elliptic flow of electrons from beauty-hadron decays extracted from Pb--Pb collision data at $\sqrt{s_{\rm NN}}$ = 2.76 TeV

## TL;DR

This paper calculates the elliptic flow of electrons from beauty-hadron decays in Pb--Pb collisions at 2.76 TeV, using ALICE data to isolate the beauty contribution and analyze its behavior in heavy-ion collisions.

## Contribution

It introduces a method to extract the elliptic flow of electrons specifically from beauty-hadron decays by subtracting charm contributions from heavy-flavour decay electron data.

## Key findings

- Elliptic flow of electrons from beauty decays is quantified.
- The analysis provides insight into heavy-quark interactions in the quark-gluon plasma.
- Results help distinguish the behavior of beauty quarks in the medium.

## Abstract

We present a calculation of the elliptic flow of electrons from beauty-hadron decays in semi-central Pb--Pb collisions at centre-of-mass energy per colliding nucleon pair, represented as $\sqrt{s_{\rm NN}}$, of 2.76 TeV. The result is obtained by the subtraction of the charm quark contribution in the elliptic flow of electrons from heavy-flavour hadron decays in semi-central Pb--Pb collisions at \snn = 2.76 TeV recently made publicly available by the ALICE collaboration.
