Using 5.4 fb(-1) of integrated luminosity from pp collisions at square root(s)=1.96 TeV collected by the D0 detector at the Fermilab Tevatron Collider, we search for decays of the lightest Kaluza-Klein mode of the graviton in the Randall-Sundrum model to ee and γγ. We set 95% C.L. lower limits on the mass of the lightest graviton between 560 and 1050 GeV for values of the coupling k/M(Pl) between 0.01 and 0.1.
利用费米实验室 Tevatron 对 pp 碰撞在 sqrt(s)=1.96 TeV 下收集到的 5.4 fb(-1)的积分亮度,我们在 Randall-Sundrum 模型中搜索最轻的引力子 Kaluza-Klein 模式衰变为 ee 和γγ。对于耦合 k/M(Pl)在 0.01 到 0.1 之间的值,我们在 560 到 1050 GeV 之间为最轻引力子设定了 95%置信度下限。
