Abstract:	大型強子對撞機將會在下個10 年進入高亮度大型強子對撞機時期並且在14 兆電子伏特質心對撞能量下運作。預期每年的總亮度為300 fb?1。在本研究中，雙希格斯玻色子生成經向量玻色子融合通道將被研究。雙希格斯玻色子會被重建為兩個AK8 噴流，向量玻色子融合噴流會被重建為兩個AK4 噴流。針對雙希格斯玻色子及向量玻色子融合拓樸設計的篩選會被採用。動力學分布及沒有堆疊跟200堆疊的比較會被呈現。對於6 個模型中理論參數的篩選通過率也會被研究。;LHC will enter the era of High-Luminosity LHC in the next 10 year and will run at sqrt(s) = 14 TeV. The designed integrated luminosity is 300 fb?1 per year. The di-Higgs production via vector boson fusion channel is probed in this analysis. The Higgs bosons are reconstructed by two AK8 jets and the VBF jets are reconstruct by AK4 jets. The selections designed for VBF topology and di-Higgs are applied. The kinematic distribution and the comparison with no pile up and 200 pile up are presented. The efficiency of each selection is also studied for six variations of the theoretical parameters in the theory model.
