Variational technique for gauge boson masses

چکیده
In this work, a novel mechanism for spontaneous symmetry breaking is presented. This avoids quadratic divergencies and thus capable of addressing the hierarchy problem in gauge theories. Using scale-dependent effective action $\Gamma_{k}$ minimally coupled to gravitational sector, variational parameter setting applied. provides mass vacuum expectation value as function constants arising low scale expansion Newtons' cosmological couplings. A comparison with experimental data, such Higgs mass, allows putting restrictions on these constants. With generic approach one can compare explicit candidates an field theory gravity. As example, we use asymptotic safety scenario, where find matter content theory.

Neutrino Masses and the Structure of the Weak Gauge Boson
A composite model of fermions is used to estimate neutrino masses. The formula for masses in the model is approximate and neglects the small masses of the electrically neutral systems (neutrino). However, in this model the electron-neutrino forms part of the structures of the weak gauge bosons (Wand Z) and, if the masses of these particles are calculated formally using the zero neutrino mass, t...
متن کاملGauge-Boson Masses and Mixings in Left-Right---Symmetric Models
The standard SU(2)t 8 U(l) gauge model' can accommodate all the present electroweak data. The recent discovery of the weak gauge bosons at CERN, with average masses M~= 80.9+ 2.0 GCV and Mz = 93.0+ 2.0 GCV, confirmed the validity of the standard model at low energies. These masses, in conjunction with the extrapolated and corrected value of the weak mixing angle, sin 0 = 0.217 + 0.014, and with...
متن کاملGenerating Vector Boson Masses
If the Higgs particle is never found, one will need an alternative theory for vector boson masses. I propose such a theory involving an antisymmetric tensor potential coupled to a gauge field.
متن کاملQuartic Gauge Boson Couplings
Quartic vertices provide a window into one of the most important problems in particle physics; the understanding of electroweak symmetry breaking. I survey the various processes that have been proposed to study quartic gauge boson couplings at future ee, eγ, γγ, e−e−, and pp colliders. For the lowest dimension operators that do not include photons, it appears that the LHC will provide the most ...
متن کاملGauge Invariance and Anomalous Gauge Boson Couplings
Using the S–matrix pinch technique we obtain to one loop order, gauge independent γWW and ZWW vertices in the context of the standard model, with all incoming momenta off–shell. We show that the vertices so constructed satisfy simple QED–like Ward identities. These gauge invariant vertices give rise to expressions for the magnetic dipole and electric quadrupole form factors of the W gauge boson...
