Abstract
A search for charged Higgs bosons produced in vector boson fusion processes and decaying into vector bosons, using proton–proton collisions at sqrt{s}=13,{text {TeV}} at the LHC, is reported. The data sample corresponds to an integrated luminosity of 137,{text {fb}}^{-1} collected with the CMS detector. Events are selected by requiring two or three electrons or muons, moderate missing transverse momentum, and two jets with a large rapidity separation and a large dijet mass. No excess of events with respect to the standard model background predictions is observed. Model independent upper limits at 95% confidence level are reported on the product of the cross section and branching fraction for vector boson fusion production of charged Higgs bosons as a function of mass, from 200 to 3000,{text {GeV}}. The results are interpreted in the context of the Georgi–Machacek model.

Summary
The discovery [1,2,3] of a Higgs boson [4,5,6,7,8,9] at the CERN LHC marks an important milestone in the exploration of the electroweak (EW) sector of the standard model (SM) of particle physics. The tree-level ratio of the W and Z boson masses is protected against large radiative corrections In this model, singly (doubly) charged Higgs bosons that decay to W and Z bosons (same-sign W boson pairs) are produced via vector boson fusion (VBF). Searches for charged Higgs bosons in these topologies have been performed by the CMS Collaboration at 13 TeV using the data sample collected during 2016 [27,28,29]. The ATLAS and CMS Collaborations have set constraints on the GM model by performing searches for charged Higgs bosons in semileptonic final states at 8 TeV [30] and 13 TeV [31], respectively
