Description
One of the most important decay channels of the standard model Higgs is its decay into a pair of bottom quarks. For the highest signal significance, the associated production of the Higgs with a W or Z boson is investigated. Six different channels are used: $W(\mu\nu)H, W(e\nu)H, W(\tau\nu)H, Z(\mu\mu)H, Z(ee)H$ and Z(\nu\nu)H$. A data sample, recorded by the CMS detector at the LHC, corresponding to integrated luminosities of 5.1 fb$^{-1}$ at $\sqrt{s} = 7$ TeV and 19 fb$^{-1}$ at $\sqrt{s} = 8$ TeV is analyzed. Exclusion limits at the 95\% confidence level and significance of signal excess with respect to the expectations for $H \to b{\bar b}$ in the mass range $110-135$ GeV are reported.
