Energy Loss of Heavy Quarks in a QGP with a Running Coupling Constant Approach Original Research Article

We show that the effective running coupling constant, αeff, and the effective regulator, View the MathML source, which we used recently to calculate the energy loss, View the MathML source, and the elliptic flow, v2, of heavy quarks in an expanding quark gluon plasma plasma (QGP) [P.

Aichelin, Phys. Rev. C79 (2009) 044906 [arXiv:0901.0946]] are compatible with lattice results and with recently advanced analytical pQCD calculation.
