Abstract
A summary of searches for Higgs bosons decaying to invisible particles using the data collected by the CMS experiment is presented. This report focuses on three stages of these analyses. First, the combination of results using data collected during the Run 1 ($\sqrt{s}=$ 7 and 8 TeV, with 24.6 $\text{fb}^{-1}$ of total integrated luminosity) and early Run 2 ($\sqrt{s}=$ 13 TeV, with 38.2 $\text{fb}^{-1}$) data taking periods is presented. This combination places a limit on the $\mathcal{B}(\text{H}\rightarrow \text{inv})$ at 0.20 (0.19) in terms of the observed (expected) 95 \% Confidence Level (CL) upper limit. It is followed by a look into the currently available results focusing on the entire Run 2 phase of data collection (137 $\text{fb}^{-1}$), namely the analyses targeting the VH production mode of the Higgs boson. Lastly, a summary of future prospects is presented in terms of the most sensitive channel of this search, indicating the possibility of further constraining the $\mathcal{B}(\text{H}\rightarrow \text{inv})$ to 0.038 during the High Luminosity (HL) phase of operation of the Large Hadron Collider (LHC).
