| Abstract: | 在一些超越標準模型中，
希格斯粒子在大強子對撞器目前研究的能量範圍內可能和其他粒子有很強的交互作用， 重夸克伴隨希格斯粒子產生過程的研究有助於我們蒐尋這些超越標準模型。 我們用MadGraph接口PYTHIA結合矩陣元方法和部分子簇射方法， 比較處理這個過程的兩個不同方法(四風味方法和五風味方法)在領頭階加上數個噴流的精確度下的模擬結果。 我們的研究顯示在考慮領頭階加上數個噴流的情況下， 四風味方法比五風味方法結果更為精確。 Some Beyond the Standard Model (BSM) Higgs particle may interact strongly with other particles at energy scales presently studied at the LHC, the study of Higgs production associated with heavy quark pairs may help us search for these BSMs. We compare two different schemes, the 4 flavour scheme and the 5 flavour scheme, to describe this process at LO + n jet by merging matrix element and parton shower approach on MadGraph 5 interface to PYTHIA. We show that the 4 flavour scheme may provide better description than the 5 flavour scheme at LO + n jet level. |
