Heavy quark three-body collisional energy loss in QGP Conference Paper

abstract

• Heavy quark drag coefficients due to three-body elastic scattering in a quark-gluon plasma have been evaluated in the lowest order in QCD. They are found to have similar values as those due to two-body elastic scattering, and both are larger than those due to two-body radiative scattering if the momenta of charm and bottom quarks are below about 4 and 9 GeV/c, respectively. Including three-body elastic scattering increases the momentum degradation of heavy quarks in QGP, bringing the nuclear modification factor for electrons from the decays of produced heavy mesons in Au+Au collisions at closer to the measured one. 2007 IOP Publishing Ltd.
