Gauge-invariant description of the Higgs resonance and its phenomenological implications
We investigate the phenomenological consequences of a strict gauge-invariant formulation of the Higgs particle. This requires a description of the observable scalar particle in terms of a bound state
The physical spectrum of theories with a Brout-Englert-Higgs effect
The physical, observable spectrum in gauge theories is made up from gauge-invariant states. In the standard model of particle physics the Fröhlich-Morchio-Strocchi mechanism shows that these states
Analytical relations for the bound state spectrum of gauge theories with a Brout-Englert-Higgs mechanism
We apply the method proposed by Frohlich, Morchio, and Strocchi to analyze the bound state spectrum of various gauge theories with a Brout-Englert-Higgs mechanism. These serve as building blocks for
Some remarks on the spectral functions of the Abelian Higgs model
We consider the unitary Abelian Higgs model and investigate its spectral functions at one-loop order. This analysis allows to disentangle what is physical and what is not at the level of the
Exploring Higgs boson Yukawa interactions with a scalar singlet using Dyson-Schwinger equations
Higgs, being the first discovery of a fundamental scalar field in the standard model (SM), opens the possibility of existence of other scalar or pseudo scalar particles in nature. Though it does not
Higgs interaction with scalar singlet via Yukawa coupling using Dyson-Schwinger equations
Higgs, being the first discovery of a fundamental scalar field in the standard model (SM), opens the possibility of existence of other scalar or pseudo scalar particles. Though it does not
Higgs stability-bound and fermionic dark matter
A bstractHiggs-portal interactions of fermionic dark matter — in contrast to fermions coupled via Yukawa interactions — can have a stabilizing effect on the standard-model Higgs potential. A
Dynamical Mass Generation in Wick Cutkosky Model
Studying extent of dynamical generation of mass in a quantum field theory, which may have non-perturbative attributes, is an essential step towards complete understanding of the theory. It has
The Abelian Higgs model under a gauge invariant looking glass: exploiting new Ward identities for gauge invariant operators and the Equivalence Theorem
Abstract The content of two additional Ward identities exhibited by the U(1) Higgs model is exploited. These novel Ward identities can be derived only when a pair of local composite operators
Studies of Wick Cutkosky model in light of its classical ground state using Dyson Schwinger equations
Implications of additional fundamental scalar fields are regarded as among the most important avenues to explore after the experimental discovery of the standard model Higgs, particularly when there

For the Yang–Mills theory coupled to a single scalar field in the fundamental representation of the gauge group, we present a gauge-independent description of the Brout–Englert–Higgs mechanism by
Accessing directly the properties of fundamental scalars in the confinement and Higgs phase
The properties of elementary particles are encoded in their respective propagators and interaction vertices. For a SU(2) gauge theory coupled to a doublet of fundamental complex scalars these
Pair production processes and flavor in gauge-invariant perturbation theory
Gauge-invariant perturbation theory is an extension of ordinary perturbation theory which describes strictly gauge-invariant states in theories with a Brout–Englert–Higgs effect. Such gauge-invariant
A study of how the particle spectra of SU(N) gauge theories with a fundamental Higgs emerge
In gauge theories, the physical, experimentally observable spectrum consists only of gauge-invariant states. In the standard model the Fr\"ohlich-Morchio-Strocchi mechanism shows that these states
Spectroscopic analysis of the phase diagram of Yang-Mills-Higgs theory
Yang-Mills-Higgs theory, being the standard-model Higgs sector for a suitable choice of gauge and custodial group, offers a rich set of physics. In particular, in some region of its parameter space
Higgs boson mass and new physics
A bstractWe discuss the lower Higgs boson mass bounds which come from the absolute stability of the Standard Model (SM) vacuum and from the Higgs inflation, as well as the prediction of the Higgs
Three Lectures on Hadron Physics
These lectures explain that comparisons between experiment and theory can expose the impact of running couplings and masses on hadron observables and thereby aid materially in charting the momentum
