A search is presented for a heavy vector resonance decaying into a Z boson and the
standard model Higgs boson, where the Z boson is identified through its leptonic decays to …

This report reviews the published results of searches for possible additional scalar particles
and exotic decays of the Higgs boson performed by the ATLAS Collaboration using up to …

Null results from searches for new physics at the Large Hadron Collider (LHC) tend to
enforce the belief that new particles must be much heavier than the weak scale. We …

Extended scalar sectors appear in various extensions of the Standard Model of particle
physics, such as supersymmetric models. They are also generic extensions of the Standard …

It was shown recently that, in two Higgs doublet models without Z 2 symmetry, extra Yukawa
couplings such as ρ tc, ρ tt can fuel enough CP violation for electroweak baryogenesis …

A bstract The exotic decay modes of non-Standard Model (SM) Higgses in models with
extended Higgs sectors have the potential to serve as powerful search channels to explore …

A generic search for resonances is performed with events containing a $ Z $ boson with
transverse momentum greater than 100 GeV, decaying into $ e^+ e^-$ or $\mu^+\mu …

A bstract We analyze heavy states from generic ultraviolet completions of the Standard
Model in a model-independent way and investigate their implications on the low-energy …

In order to identify the Higgs sector using future precision data, we calculate the partial
decay widths of the discovered Higgs boson with the mass of 125 GeV into fermion pairs …

A bstract We outline a scenario where both the Higgs and a complex scalar dark matter
candidate arise as the pseudo-Nambu-Goldstone bosons of breaking a global SO (7) …
