“…Also, as soon as there are more complicated Higgs sectors, and thus more parameters, the argument also breaks down, even if the gauge group is fully broken by the BEH effect. The theory may then become quite involved with a rich phase structure [84,[179][180][181][182]. This issue will be returned to in section 4.8.…”

“…Since any gauge-invariant state, as in QCD, always contains either an higgs and an anti-higgs or three higgs particles or combinations thereof [177,205,276], only states with zero or multiples of three times the higgs particles' custodial charge can be gauge invariant. If the theory has a more complicated custodial structure, the possibilities quickly proliferate [177,180,181,201].…”

“…In the following, only the situation for the gauge sector and the higgs fields will be analyzed. For an enlarged custodial symmetry the remainder of the standard model seems to be possible to include as in the standard model case [181]. This is not even perturbatively true if the gauge group is enlarged beyond a direct-product structure [14,85].…”

“…In the Higgs basis it is possible to copy verbatim for each of the custodial groups the results of section 4.5.1, as long as the entity is a singlet with respect to the other custodial group [181]. Thus, for the custodial group involving the higgs condensate this creates again a scalar and a triplet of vector bosons, with the mass of the corresponding higgs and the w bosons.…”

Brout-Englert Higgs physics is one of the most central and successful parts of the standard model. It is also part of a multitude of beyond-the-standard-model scenarios.The aim of this review is to describe the field-theoretical foundations of Brout-Englert-Higgs physics, and to show how the usual phenomenology arises from it. This requires to give a precise and gauge-invariant meaning to the underlying physics. This is complicated by the fact that concepts like the Higgs vacuum expectation value or the separation between confinement and the Brout-Englert-Higgs effect loose their meaning beyond perturbation theory. This is addressed by carefully constructing the corresponding theory space and the quantum phase diagram of theories with elementary Higgs fields and gauge interactions.The physical spectrum needs then to be also given in terms of gauge-invariant, i. e. composite, states. Using gauge-invariant perturbation theory, as developed by Fröhlich, Morchio, and Strocchi, it is possible to rederive conventional perturbation theory in this framework. This derivation explicitly shows why the description of the standard model in terms of the unphysical, gaugedependent, elementary states of the Higgs and W -bosons and Z-boson, but also of the elementary fermions, is adequate and successful.These are unavoidable consequences of the field theory underlying the standard model, from which the usual picture emerges. The validity of this emergence can only be tested non-perturbatively. Such tests, in particular using lattice gauge theory, will be reviewed as well. They fully confirm the underlying mechanisms.In this course it will be seen that the structure of the standard model is very special, and qualitative changes occur beyond it. The extension beyond the standard model will therefore also be reviewed. Particular attention will be given to structural differences arising for phenomenology. Again, non-perturbative tests of these results will be reviewed.Finally, to make this review self-contained a brief discussion of issues like the triviality and hierarchy problem, and how they fit into a fundamental field-theoretical formulation, is included. If there is no gauge-invariant way of defining the vacuum expectation value of the Higgs, the whole standard procedure [14] of doing BEH physics seems to collapse on itself at first. This seems to question the whole basis of the current theoretical description of experiments, despite its huge success [10]. But it does not. Rather, it can be shown that a treatment taking the gauge-dependence into account will lead to, essentially, the same results for the standard model.How this works out is exactly the core of this review: The construction of a fully gauge-invariant description of this physics, and how the standard phenomenology follows from it. This starts in section 3. There, a gauge-invariant description of the theory (3) will be set up. This is the first step of developing a comprehensive, field-theoretical consistent view on BEH physics. This view is continued by establis...

“…Minimal Landau gauge corresponds to an average with flat weight over all Gribov copies in the first Gribov region, i. e. those Gribov copies with positive semidefinite Faddeev-Popov operator [3]. The employed algorithms appears to implement this prescription faithfully, as far as has been investigated [34]. However, at least the fundamental scalar propagator in the unquenched theory shows essentially no dependence on how Gribov copies are treated, in contrast to the gauge propagators [35].…”

The question of whether confining effects are visible in correlation functions is a long-standing one. Complementing investigations on the propagators of fundamental and adjoint scalar matter particles here the quenched scalar-gluon vertex is investigated. For this purpose a multitude of lattice setups in two, three, and four dimensions is analyzed in quenched SU(2) lattice gauge theory. Though both cases are quantitatively different, neither a qualitative difference nor any singularities are observed.

Antireflective coating helps to reduce reflectance losses, thereby improving photovoltaic (PV) efficiency. Improving PV efficiency while maintaining low innovation cost has been a challenging task for the PV industry, especially in the case of monocrystalline silicon. Herein, the feasibility of integrating polydimethylsiloxane foil onto the protecting glass of an n‐type tunnel oxide–passivated contact silicon cell is studied. The foil is made using a polymer molding technique with digital video disk templates. On average, the foil provides 5.2% total reflectance and 93.5% total transmission. Under 1 sun illumination, the cell's power‐conversion efficiency increases by 12% (among the highest improvement), from 17.3% to 19.3%, in the presence of foil. A combined set of optical spectroscopy and simulation data shows that this improvement is due not only to the index‐matched medium, but also to forward scattering that increases broadband light transmission to the silicon cell through the foil which is different to the prevalent light‐trapping mechanism. The foil is also evaluated under different illumination conditions (indoors and outdoors), which show that the cell's power output nearly doubles at dimmer illumination levels and is stable under a fluctuating light source. While effective, the feasibility of antireflective foil should be reexamined further.
