A bstract We present a dedicated complementarity study of gravitational wave and collider
measurements of the simplest extension of the Higgs sector: the singlet scalar augmented …

The recent Fermilab measurement of the muon anomalous magnetic moment yields 4.2 σ
deviations from the SM prediction when combined with the BNL E821 experiment results. In …

Insight into the electroweak (EW) and Higgs sectors can be achieved through
measurements of vector boson scattering (VBS) processes. The scattering of EW bosons are …

We investigate the possibilities of probing the electroweak scale seesaw scenarios such as
type-I, type-II, and type-III seesaw at e-γ and γ γ colliders. For the case of type-I seesaw, the …

A bstract The invariance of physical observables under redefinitions of the quantum fields is
a well-known and important property of quantum field theory. We study perturbative field …

A dark sector is an interesting place where a strong first-order phase transition, observable
gravitational waves and/or a dark matter candidate could arise. However, the experimental …

We introduce a new approach to the Higgs naturalness problem. The Higgs mixes with the
dilaton of a conformal field theory (CFT) sector whose true ground state has a large negative …

The standard model of particle physics is an extremely successful theory of fundamental
interactions, but it has many known limitations. It is therefore widely believed to be an …

The measurement of the triple Higgs coupling is one of the main tasks of the (HL-) LHC and
future lepton colliders. Similarly, triple Higgs couplings involving BSM Higgs bosons are of …

We reanalyze the effective field theory approach for the scenario in which the particles that
account for the dark matter (DM) in the universe are vector states that interact only or mainly …
