论文摘要
我们认为，在拟议的大型强子电子对撞机上，Higgs Boson对W $^{+} $ W $^{ - } $的衰变，并确定从其衰减产品W Jets降低了削减候选候选喷气式和优化Angular $ nepular $ΔR的价值，从而确定从其衰减产品W Jets中检测到Higgs Mass信号的可能性。已经发现，在LHEC实验（CM Energy $ \ sqrt {s} = 1.3 $ TEV和每年100 fb $^{ - 1} $的发光度），使用$ΔR= 0.4 $获得最高效率，以及$ |δη| <1，10 <m <85 $ gev，$ p_t $ jet $ 1和2介于$ 10-20 $ gev和$ p_t $ jets 3和4 $> 10 $ gev的$ p_t $ gev：这导致效率在$ 7.1-7.5 \％之间，以在$ <140美元的$ <140 $ gev中找到$ 7.1-7.5 \％$ $。在信噪比的比较下，与带电的电流W $^{ - } $背景相比，该信号显示出$3.8σ$的过量。
We consider the decay of the Higgs boson to W$^{+}$ W$^{-}$ at a proposed Large Hadron Electron Collider and determine the likelihood of detecting a signal for the Higgs mass from its decay product W jets by imposing cuts to select candidate jet pairs and optimizing the value of the angular separation $ΔR$. It was found that at the LHeC experiment (CM energy $\sqrt{s}=1.3$ TeV and luminosity of 100 fb$^{-1}$ per year), the highest efficiency is obtained with $ΔR = 0.4$, along with a selection scheme of $|Δη| <1, 10<m<85$ GeV, $p_T$ of jets 1 and 2 between $10 - 20$ GeV and $p_T$ of jets 3 and 4 $>10$ GeV: this led to an efficiency between $7.1 - 7.5 \%$ for finding the invariant 4-jet mass in a mass region $<140$ GeV. Under signal-to-background comparison, the signal showed a $3.8 σ$ excess compared to the charged current W$^{-}$ background.
