Abstract:

A search for the standard model (SM) Higgs boson (

\mathrm{H}

) decaying to

\mathrm{b\overline{b}}

when produced in association with a weak vector boson (

\mathrm{V}

) is reported for the following processes:

\mathrm{Z}(\nu\nu)\mathrm{H}

,

\mathrm{W}(\mu\nu)\mathrm{H}

,

\mathrm{W}(e\nu)\mathrm{H}

,

\mathrm{Z}(\mu\mu)\mathrm{H}

, and

\mathrm{Z}(ee)\mathrm{H}

. The search is performed in data samples corresponding to an integrated luminosity of

35.9~\mathrm{fb}^{-1}

at

\sqrt{s}=13~\mathrm{TeV}

recorded by the CMS experiment at the LHC during

\mathrm{Run~2}

in 2016. An excess of events is observed in data compared to the expectation in the absence of a

\mathrm{H}\to\mathrm{b\overline{b}}

signal. The significance of this excess is

3.3

standard deviations, where the expectation from SM Higgs boson production is

2.8

. The signal strength corresponding to this excess, relative to that of the SM Higgs boson production is

1.2 \pm 0.4

. This result is combined with the one from the search for the same processes performed by the CMS experiment in

\mathrm{Run~1}

of the LHC (using proton-proton collisions at

\sqrt{s}=7

and

\sqrt{s}=8~\mathrm{TeV}

with data samples corresponding to luminosities of up to

5.1~\mathrm{fb}^{-1}

and

18.9~\mathrm{fb}^{-1}

, respectively). The observed combined signal significance is

3.8

standard deviations, where

3.8

are expected from a SM signal. The corresponding signal strength, relative to that of the SM Higgs boson, is

1.06^{+0.31}_{-0.29}

.
