Combined analysis of jet substructure for Higgs decay to $b\bar{b}$ in vector boson associated production at the 13 TeV LHC (1701.08413v1)

Abstract: We study the Standard Model Higgs and vector boson associated production with large transvese momentum at the 13 TeV LHC, followed by Higgs decay to bottom quark pair. Using mass-drop tagging and filtering techiques, we obtained the cross section of signal and background. The background mainly come from $Vb\bar{b}$, $t\bar{t}$ and single top production. In order to suppress them further, we combined the mass-drop tagging and filtering analysis with $N$-subjettiness jet shape. After performing $N$-subjettiness identification, the significance can be enhanced to 3.52$\sigma$ with current integrated luminosity of $13.2 {\rm fb}^{-1}$. $H\to b\bar{b}$ decay channel is expected to reach 5$\sigma$ with $27\,{\rm fb}^{-1}$ at the 13 TeV LHC.
