Available in PDF, EPUB and Kindle. Book excerpt: A search for the CP-violating electric dipole (E1) direct emission contribution to the KL → [pi]+[pi]-[gamma] decay is performed using data from the 1997 KTeV/E832 experiment. Because the KL → [pi]+[pi]-[gamma] decay mode is massively dominated by the CP-violating inner bremsstrahlung (IB) and the CP-conserving magnetic dipole (M1) direct emission processes, previous analyses have neglected the E1 contribution. Therefore, this measurement is the first attempt to directly quantify the size of the E1 decay process. This E1 transition is one of the very few CP-violating processes that is accessible to experiment and, in principle, will produce new insights into the structure of the neutral kaon. The result of this analysis is that the E1 contribution is below the threshold of sensitivity, and therefore an upper bound of

Book excerpt: With the E731 apparatus at Fermilab, we have simultaneously collected 6859 K(L) and K(S) decays into pi+pi-gamma. Using our sample of over 370000 pi+pi- decays for normalization we have determined that the ratio GAMMA(K0 --> pi+pi-gamma)/GAMMA(K0 --> pi+pi- ) is (23.0 +/- 0.7) x 10( -3) for K(L) and (7.10 +/- 0.22) x 10( -3) for K(S), for photon energies greater than 20 MeV in the kaon center of mass. After removing the inner-bremsstrahlung contribution, we find that the photon energy spectrum of the direct emission decay of the K(L) is consistent with the presence of a vector meson propagator in the form factor.

This book was released on 2006 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NA48/2 experiment at the CERN SPS has collected a large sample of K to pi pi0 gamma decays.Two amplitudes contribute to these decays. The dominant one comes from Inner Bremsstrahlung (IB) in the K to pi pi0 process. The second one is given by the Direct Emission (DE) of the photon at the weak vertex from an intermediate state of the decay. The simplest radiative transitions are electric dipole (E1) and magnetic dipole (M1). Electric amplitudes can interfere with IB, and CP violation and possible non-SM effects can show up in th e corresponding interference (INT) term.In this work a sub sample of the data has been analyzed. About 120000 K to pi pi0 gamma decays, with negligible background contamination have been reconstructed in the ranges 0.2

This book was released on 1993 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fermilab experiments E731, E773, E799, and E832 are a series of experiments to investigate the physics of CP violation, CPT violation, and rare decays of the neutral kaon system. E731 finished data taking in 1988, during past year the full data set analysis was completed and yielded ([var epsilon][prime]/[var epsilon])[sub 2[pi]]=(7.4 [plus minus] 5.2 [stat] [plus minus] 2.9 [syst]) [times] 10[sup [minus]4] . The value favors a high top ark mass value within the Standard Model. E773 tests CPT violation by determining ([Delta][phi])[sub 2[pi]] with an accuracy of about 0.5[sup 0]. Data were taken during the last Fermilab Fixed Target run period between September and November 1991. It is anticipated the data analysis will be finished within a year. E799, with the primary goal of observing direct Cp Violation via searching for the rare decay K[sub L][yields] [pi][sup 0] l [sup +]l[sup [minus]] (where l = e, [mu] [nu]) took test data between November 1991 and January 1992 (Phase 1). Some preliminary results are shown here. E799 (Phase II) and E832 (a follow up experiment of E731) are scheduled to take data after the current Fermilab collider run with a new facility and detector.
