Threshold Effects on Heavy Quark Production in $\gamma \gamma$ Interactions

O. J. P. Eboli, M. C. Gonzalez-Garcia, F. Halzen +1

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 $\gamma \gamma$ c…
