寻找难以捉摸的引力子
Searching for the elusive graviton
摘要:
我们提出了一个搜索大额外的尺寸在单光子加上失踪的横向能量通道(卡鲁扎-克莱因引力子生产)进行使用2.7 fb-1的D 0实验收集的数据在费米实验室Tevatron对撞机。在95% C. L.时,我们将基本普朗克尺度M_{D}的极限设置为从970 GeV到816 GeV,用于2到8个额外维度。
英文摘要:
We present a search for large extra dimensions in the single photon plus missing transverse energy channel (Kaluza-Klein graviton production) performed using 2.7 fb-1 of data collected by the D0 experiment at the Fermilab Tevatron collider. At 95% C.L., we set limits on the fundamental Planck scale M_{D} from 970 GeV to 816 GeV for two to eight extra dimensions.
