# Elliptic flow coefficients from transverse momentum conservation

@article{Bzdak2018EllipticFC, title={Elliptic flow coefficients from transverse momentum conservation}, author={Adam Bzdak and Guoliang Ma}, journal={Physical Review C}, year={2018}, volume={97}, pages={014903} }

We calculate the $k$-particle ($k=2,4,6,8$) azimuthal cumulants resulting from the conservation of transverse momentum. We find that $c_2\{k\}>0$ and depending on the transverse momenta, $c_2\{k\}$ can reach substantial values even for a relatively large number of particles. The impact of our results on the understanding of the onset of collectivity in small systems is emphasized.

The established changes in the ratio of the redox forms of ubiquinone and the degree of oxidative modification of mitochondrial proteins in rat liver could be considered as prerequisites for deepening the energy imbalance and violation of the functional activity of mitochondria under conditions of nutritional imbalance.
