Observation of Highly Virtual Photon-Photon Collisions to Hadrons at TRISTAN

Ryoji Enomoto

We have observed highly virtual ( $Q^{2} > 1.05 G e V^{2}$ ) photon-photon collisions to hadronic final states at $s_{e^{+} e^{-}} = 58 G e V$ . The integrated luminosity of the data sample was…

Observation of Excess $Λ (Λ ˉ)$ Production in Two-Photon Processes at TRISTAN

R. Enomoto

We have carried out inclusive measurements of $Λ (Λ ˉ)$ production in two-photon processes at TRISTAN. The mean $s$ was 58 GeV and the integrated luminosity was 265 pb$^{-1…

Measurement of the forward-backward asymmetries for charm- and bottom-quark pair productions at $< s >$ =58GeV with electron tagging

E. Nakano

We have measured, with electron tagging, the forward-backward asymmetries of charm- and bottom-quark pair productions at $< s >$ =58.01GeV, based on 23,783 hadronic events sel…

Measurement of inclusive electron cross section in $γ γ$ collisions at TRISTAN

M. Iwasaki

We have studied open charm production in $γ γ$ collisions with the TOPAZ detector at the TRISTAN $e^{+} e^{-}$ collider. In this study, charm quarks were identified by electrons (and…

$K^{0} (K^{0} ˉ)$ Production in Two-Photon Processes at TRISTAN

R. Enomoto

We have carried out an inclusive measurement of $K^{0} (K^{0} ˉ)$ production in two-photon processes at TRISTAN. The mean $s$ was 58 GeV and the integrated luminosity was 199…

Measurement of the $D^{*\pm}$ Cross Section using a Soft-Pion Analysis in Two-Photon Processes

R. Enomoto

The differential cross section of $d σ (e^{+} e^{-} \to e^{+} e^{-} D^{*\pm} X) / d P_{T}$ was measured using a soft-pion analysis of $D^{*\pm} \to π_{s}^{\pm} D^{0} (D^{0} ˉ)$ at TRISTAN. The average $\sqr…
