After a Higgs boson with a mass near 125 GeV has been discovered, it is still unclear whether this is the Higgs boson predicted by the standard model (SM) or part of an extended Higgs sector, which is expected in various well-motivated beyond-the-SM models such as the minimal and next-to-minimal supersymmetric extensions (MSSM and NMSSM) of the SM. Direct searches for additional Higgs bosons...

Based on latest LHC Higgs search results, we find constraints on theory parameters of the Georgi-Machacek Model. In particular, we obtain upper bounds on the triplet vacuum expectation value as a function of exotic Higgs masses and the mixing angle alpha between the two custodial singlets. We also scrutinize the small-mass region in the diphoton channel.

We explore Higgs production via vector boson fusion in the Georgi-Machacek (GM) model. The GM model adds isospin triplet scalars to the SM while preserving custodial SU(2) symmetry. The model contains a custodial quintuplet of Higgs bosons which are phenomenologically distinct from the states of the SM or the 2HDM. The quintuplet is fermiophobic, making vector boson fusion the primary...

Effective field theory provides an excellent way to organize the modifications to the Standard Model Higgs properties, in the case of an extended Higgs sector.
In this talk, we present the low energy theories for the Higgs sector for some of the most popular beyond the standard model UV completions. For brevity, we only consider the Higgs sector extended with a real singlet (xSM) and with...

The most recent results from CMS searches for heavy scalar (H) and pseudoscalar (A) Higgs bosons predicted in the minimal supersymmetric standard model (MSSM) and in the (2HDM) extensions of the standard model (SM) will be presented.
These searches are based on a data sample of pp collisions collected with the CMS experiment at the LHC at a center-of-mass energy of s√=8 TeV and...

We assess the current state of searches at the LHC for additional Higgs bosons in light of both direct limits and indirect bounds coming from coupling measurements of the Standard Model-like Higgs boson. Given current constraints, we identify and study three LHC searches that are critical components of a comprehensive program to investigate extended electroweak symmetry breaking sectors:...

Besides the SM-like Higgs boson discovery, it is also important to assess all possibilities for other Higgs-like states that are built in the extended Higgs sector and may have escaped detection at Run 1 of the LHC. One often considered the limit is the decoupling limit in which one scalar Higgs is SM-like and others are very heavy. A SM-like scalar Higgs boson can however also be obtained in...

As a landmark of BSM physics, the MSSM Higgs sector has been tested up to
hundreds of GeV at the LHC, except for the moderate $tan\beta$ region. We present a study covering this region at the LHC and a next-generation pp-collider. We propose to search not only in channels with single Higgs production but also with associated Higgs productions. A multivariate method of Boosted Decision Tree is...
