چکیده

This result, obtained at the Stanford Linear Accelerator Center (SIX), is a prima facie demonstration of CP non-invariance in Kz" decay. It is consistent with theoretical expectations based upon an analysis of experimental data which has been obtained since the first such demonstration by Christenson, Cronin, Fitch and Turlay. (1) The analysis of KzO decay in terms of parameters characterizing the CP violation has been carried out by a number of authors. c%3,4) It is most convenient to make use of the four parameters q+-, qoo, E and E' as follows:

Leptons and Photons

It is assumed that three lepton families (ν e , e), (ν µ , µ), (ν τ , τ) carry charges, which are sources of electronic, muonic and tauonic massless vector particles, respectively. Various manifestations of these hypothetical photons are discussed. We know only one photon that is coupled to the electric charge of particles. One of the most fundamental properties of the electric charge is its co...

Latest Results on Weak Semi-Leptonic Hyperon Decays in KTeV

This suggestion of the author was shown to be accessible in KTeV because even though there was no charged particle vertex, the π decay into two gammas and the high precision electronmagnetic calorimeter permits the vertex to be precisely measured by constraining to the π mass [8]. This along with the high flux of Ξ hyperons in the experiment permitted these analysis. Hyperon semi-leptonic decay...

X-ray emission during the muonic cascade in hydrogen

We report our investigations of X rays emitted during the muonic cascade in hydrogen employing charge coupled devices as X-ray detectors. The density dependence of the relative X-ray yields for the muonic hydrogen lines ( Kα, Kβ and Kγ) has been measured at densities between 0.00115 and 0.97 of liquid hydrogen density. In this density region collisional processes dominate the cascade down to lo...

Application of large-area avalanche photodiodes to X-ray spectrometry of muonic atoms

Large-area avalanche photodiodes have been investigated as 1.9-keV X-ray detectors for the muonic hydrogen Lamb-shift experiment. We report experimental tests carried out for evaluation of the avalanche photodiode capabilities for X-ray detection in the intense radiation and low counting rate environment of experiments with muonic atoms. Several muonic atoms were used and it was shown that the ...

On CP violation and the measurement of the dimuon charge asymmetry at hadron colliders

B factories measure the CP violation parameter of BB̄ mixing and decay. Hadron colliders measure the dimuon charge asymmetry of an admixture of B hadrons. In this note we discuss a subtle point on how the CP violation parameter of B s B̄ 0 s mixing and decay can be extracted from these measurements.
