After the discovery of the Higgs boson about ten years ago, its properties are being measured to understand its exact nature in detail. One of the current mandates is to precisely measure its couplings with other particles, since physics beyond the standard model is likely to affect them. The Higgs-bottom quark Yukawa coupling is directly accessed from the decay of the Higgs boson to a pair of bottom quarks. However, experimental observation in the LHC experiments is challenging due to the large rate of bottom quark pair production due to strong interactions. The Yukawa coupling of the bottom quark has already been measured by the LHC experiments using associated production of Higgs with W or Z bosons, where the leptonic decay channels of the latter have been utilized. Since the production mode of the vector boson fusion (VBF) process has a higher rate, the resulting measurement is expected to be more accurate. However, identification of VBF production followed by the decay to b quark pair is experimentally very difficult, being an all-hadronic final state with at least four jets. In this seminar we shall discuss the strategy being followed for analysis of data collected by the CMS experiment during Run2 operation of the LHC. Finally, we shall also present the preliminary results from the ongoing studies.
