Figure 2. The ratio ${\sigma }_{P}/\sigma $ of ${e}^{-}\gamma \to {\bar{T}}_{+}b{\nu }_{e}$ cross sections at polarizations ${P}_{{e}^{-}}$ and ${P}_{\gamma }$, for f = 800 GeV, R = 1 (${m}_{T}\,\approx $ 1120 GeV) at $\sqrt{s}$ = 2 TeV. ${\sigma }_{P}$ denotes the polarized cross section, and σ denotes the unpolarized cross section.
