(3.28) to rescale the Z boson field by Z0,µ →λ−Z01Z0,µ = 1 − λ(+,+) f01 m2Z m2(+,+) −1 Z0,µ . (6.4) As explained above we focus here on the lighter generations of UV localized fermions, for which λ(+,+) ≡λ(+,+)(c > 0.5) is independent of the...
which is automatically aligned in the simplest realisations. We show that raising the scale at which the extended supersymmetry is manifest and including quantum corrections actually improves the alignment. Using an effective field theory approach ...
For this purpose, the detector card from CMS was used and also the magnetic field of the ATLAS detector was changed from 2T to 2.1T. In Table 2 an overview of all the simulated data is shown. Frequently, the same number of signal and background events are simulated to have a balanced ...
Observations of the weak force (exchanged by the W and Z particles) cannot be explained without the inclusion of the Higgs field. OK, so we have a “Higgs field,” where does the “Higgs boson” come into it? The Higgs particle is simply the boson that carries the Higgs field. So if...
the Higgs field, as it does so, it distorts the surrounding field, causing it to bunch up around the particle, thus giving it mass and therefore momentum. Observations of the weak force (exchanged by the W and Z particles) cannot be explained without the inclusion of the Higgs field. ...
This theory, known as Theory X, is a 6d (0,2)-superconformal field theory with no classical Lagrangian description. As explained in [23, Data 5.1], the data required to specify a Theory X is (1) A real Lie algebra g with an invariant inner product 〈−,−〉 such that all co...
Rumours about particle discoveries are as old as the field itself, but the ease of commu- nicating tentative finds via the Internet means that particle hunters' first clues and false starts are now being discussed on the global stage. This raises broader questions for a discipline that employs...
The ratio of neutral Higgs field vacuum expectation values, tanβ, is one of the most important parameters to determine in either the minimal supersymmetric standard model (MSSM) or a general type-II two-Higgs doublet model (2HDM). Assuming an energy and integrated luminosity of s=500 GeV ...
order of Eq. (5) or Eq. (7) since these introduce a non-physical behavior for the would-be observable masses: namely an explicit dependence on\xiand the field renormalization. The combined impact of these artifacts on the mass determination competes with the magnitude of the leading two-...
We perform a global fit within a well-defined Higgs boson EFT framework assuming SM gauge and global symmetries and a SM field content. We focus on the phenomenology of the Higgs boson that can be cast into narrow width approximation calculations, ...
