在$\sqrt{s}=1.96$ TeV上使用D0检测器搜索$h_f\toγγ$

Search for $h_f\toγγ$ with the D0 detector at $\sqrt{s}=1.96$ TeV

D0 Collaboration, V. Abazov

摘要:

我们报告的搜索结果的窄共振衰减成两个光子在1.1 FB $^{-1}$的数据收集的D0实验在费米实验室Tevatron对撞机在2002年至2006年期间。我们没有发现这种共振的证据,并在95% C. L.处设定了$m_{h_f}>100$ GeV的希格斯玻色子的质量下限。这个排除限制超过了在Tevatron以前的搜索中获得的限制,并且覆盖了参数空间$B(h_{f}\toγγ)$与$m_{h_f}$的重要区域,这在CERN LEP对撞机上是无法访问的。

英文摘要:

We report the results of a search for a narrow resonance decaying into two photons in 1.1 fb$^{-1}$ of data collected by the D0 experiment at the Fermilab Tevatron Collider during the period 2002-2006. We find no evidence for such a resonance and set a lower limit on the mass of a fermiophobic Higgs boson of $m_{h_f}>100$ GeV at the 95% C.L. This exclusion limit exceeds those obtained in previous searches at the Tevatron and covers a significant region of the parameter space $B(h_{f}\toγγ)$ vs. $m_{h_f}$ which was not accessible at the CERN LEP Collider.
