Theory of the Electroweak Interactions

2017
In Chap. 5 we already talked about the phenomenological Fermi theory, as well as the modern fundamental electroweak theory (the Standard Model), and described their salient features in words and pictures. Since then, we have learned a lot of new stuff (what are fermion fields, what is a field theory Lagrangian, how to calculate scattering amplitudes ...

Electroweak interactions at LEP

AIP Conference Proceedings, 2001
The electroweak interactions are based on an extension of the electromagnetic (Maxwell) interactions, realized in a rather odd way so that the symmetries of the theory are not immediately obvious. This “broken” theory has been the subject of intense investigation at LEP, and has passed all tests with flying colors.

Measurement of the electroweak production of dijets in association with a Z-boson and distributions sensitive to vector boson fusion in proton-proton collisions at sqrt(s) = 8 TeV using the ATLAS detector

, 2014
Measurements of fiducial cross sections for the electroweak production of two jets in association with a Z-boson are presented. The measurements are performed using 20.3 inverse femtobarns of proton-proton collision data collected at a centre-of-mass ...

Electroweak Interactions of Leptons

1999
We will now use the knowledge gained from the model-building in Chap. 9 to construct a theory of the weak and the electromagnetic interactions of physical particles. In this first chapter we will consider only the interactions between leptons, restricting for simplicity ourselves first to a treatment of the electron and its neutrino.

Standard Theory of Electroweak Interactions [PDF]

, 2003
In the four-Fermi interaction the neutrino interacts with the electron via the V-A current of the form $$\overline {e{\gamma _\mu }} (1 - {\gamma _5})v$$ (2.1) .

CP violation and the CKM matrix: assessing the impact of the asymmetric B factories

, 2004
.We present an up-to-date profile of the Cabibbo-Kobayashi-Maskawa matrix with emphasis on the interpretation of recent CP-violation results from the B factories.

Electroweak Interactions of Quarks

1999
So far we have considered only electroweak interactions between the leptons. In this chapter we will now extend this discussion to processes involving hadrons.

Electroweak interactions with nuclei

AIP Conference Proceedings, 1984
Selected electron scattering applications and tests of the Standard Model involving semileptonic weak interactions with nuclei are discussed. The current picture of strong and electroweak interactions in the nucleus is examined.

Electroweak measurements of neutron densities in CREX and PREX at JLab, USA

, 2013
Measurement of the parity-violating electron scattering asymmetry is an established technique at Jefferson Lab and provides a new opportunity to measure the weak charge distribution and hence pin down the neutron radius in nuclei in a relatively clean ...

PRECISION TESTS OF THE ELECTROWEAK INTERACTIONS

International Journal of Modern Physics A, 2005
The status of the precision test of the ElectroWeak interactions is reviewed in this paper. Special emphasis is put on new results at low Q2: the anomalous magnetic moment of the muon from E821 at Brookhaven and new measurements of sin 2θ eff . The status of the measurements at high Q2 is also reviewed, and the internal consistency of the Minimal ...
