Both are present, because both mixing and decay arise from the same interaction with the W boson and thus have CP violation predicted by the CKM matrix.
22.
Much rarer is the decay into a pair of photons mediated by a loop of W bosons or heavy quarks, which happens only twice for every thousand decays.
23.
In LEP's second phase from 1996 to 2000, the collider's collision energy was increased to make pairs of W bosons, and to search for possible new particles and new physics.
24.
Similar precision measurements will be made of other known particles; for example, ATLAS may eventually measure the mass of the W boson twice as accurately as has previously been achieved.
25.
Kotwal leads the world in measuring the mass of the W boson, which is connected to the Higgs boson, using the data from the CDF and D0 experiments at Fermilab.
26.
He is the Fritz London Professor of Physics at Duke University, and conducts research in particle physics related to W bosons and the Higgs boson and searches for new particles and forces.
27.
Highlights in CERN's history have included the 1984 Nobel physics prize going to Carlo Rubbia and Simon van der Meer for their discovery of two particles, the W boson and Z boson.
28.
While the regular Z and W bosons interact with the left-handed particles while completely ignoring the right-handed particles, the Z'and W'are supposed to interact with the right-handed particles while ignoring the left-handed ones.
29.
Note that in a typical non-abelian gauge theory the gauge boson carries the charge of the theory, and hence has interactions of this kind; for example, the W boson in the electroweak theory.
30.
Veltman initially developed the program to compute the quadrupole moment of the W boson, the computation of which involved " a monstrous expression involving in the order of 50, 000 terms in intermediate stages"
