Threshold Effects on Heavy Quark Production in $γγ$ Interactions
arXiv:hep-ph/9210277 · doi:10.1103/PhysRevD.47.1889
Abstract
The exchange of gluons between heavy quarks produced in $e^+e^-$ interactions results in an enhancement of their production near threshold. We study QCD threshold effects in $γγ$ collisions. The results are relevant to heavy quark production by beamstrahlung and laser back-scattering in future linear collider experiments. Detailed predictions for top, bottom and charm production are presented.
