41. Rare pion and kaon decays

Dr Toshio Numao (TRIUMF)

09/09/2013, 14:30

Fundamental physics with e, mu, pi, n, pbar, nuclei, atoms

Oral

The present status of pion and kaon decay experiments will be discussed. The focus will be on precision measurements of the decay modes allowed and cleanly caluculated in the Standard Model (SM) but suppressed by some mechanisms that enable a sensitive test of physics beyond the SM.

14. Kaon experiments at CERN: recent results and prospects

Francis Newson (University of Birmingham, UK)

Fundamental physics with e, mu, pi, n, pbar, nuclei, atoms

Oral

The NA62 experiment at CERN collected a large sample of charged kaon decays with a low intensity beam and minimum bias trigger conditions in 2007. This allowed measurements of a number of rare decays that are difficult to address in conventional experiments with selective triggers. Recent results based on this data sample is presented. The status of the next stage of the NA62 experiment...

33. Search for lepton universality violation in kaon two-body decays

Prof. Jun Imazato (KEK)

Fundamental physics with e, mu, pi, n, pbar, nuclei, atoms

Oral

An experiment (E36) to search for lepton universality violation is planned at J-PARC. The ratio of decay widths of K_{e2} and K_{mu2} will be measured precisely using a high-intensity low-momentum kaon beam. In contrast to NA62 experiment at CERN the stopped beam technique is employed. The TREK detector, originally designed for T-violation search in K_{mu3} decays, will be used. The ratio may...

71. Standard Model Tests with Coherent Neutrino Scattering

Dr Robert Cooper (Indiana University)

09/09/2013, 15:40

Low energy precision tests of the Standard Model

Oral

Neutrinos with sufficiently low energy (E < 50 MeV) have a wavelength that is larger than its scattering target nuclei, and the neutrino can engage in pure coherent elastic neutrino-nucleus scattering with very low neutral current momentum transfer. At these energies, the coherent scattering cross section dominates, but because it deposits very little energy, low detection thresholds (~10...
