42. Beyond SM expectations from very rare Kaon decays

Dr Cecilia Tarantino (Technical University of Munich)

Rare decays

Rare decays dominated by one-loop electroweak dynamics offer a very powerful tool to investigate the flavour structure of physics beyond the Standard Model (SM). Among them, the kaon rare decays K+ into pi+ nu nubar and Klong into pi0 nu nubar play a privileged role because of their strong suppression within the SM and the high-level of accuracy achieved in their theoretical description....

46. Recent progress on supersymmetric effects in rare K decays

Dr Christopher Smith (University of Bern)

Rare decays

Supersymmetry offers one of the most attractive extensions of the Standard Model. Intensive searches for supersymmetric partners will soon start at the LHC. In that context, rare K decays will play an essential role, complementary to direct searches at colliders. Indeed, they allow us to study in an exceptionally clean way the flavor breaking structures. In the minimal supersymmetric...

47. The $K^+\rightarrow\pi^+\nu\bar{\nu}$ experiment at CERN

Dr Giuseppe Ruggiero (Scuola Normale Superiore, Pisa)

Rare decays

The NA48/3-P326 proposal for an experiment to measure the branching ratio of the very rare kaon decay $K^+\rightarrow\pi^+\nu\bar{\nu}$ at the CERN SPS will be described. The proposed experiment aims to collect about 80 $K^+\rightarrow\pi^+\nu\bar{\nu}$ events with a 10\% of background in two years of data taking. The status of the project, the R\&D and the future perspectives for the...

49. Recent Progress by the E391a Collaboration

Mr Gabriel Perdue (The University of Chicago)

25/05/2007, 11:40

Rare decays

We will provide a status report on the E391a experiment conducted at KEK. Following a brief introduction to the experiment, we will discuss several of the current analysis topics, with a focus on the Monte Carlo and Kaon-related backgrounds. Additionally, we will discuss a new method for estimating the photon veto inefficiency for some detectors using actual data that is well-suited...

60. A search for KL-> pi0 nu nubar at KEK-PS E391a experiment

Mr Toshi Sumida (Dept. of Physics, Kyoto University)

25/05/2007, 12:00

Rare decays

The rare decay KL-> pi0 nu nubar is a Flavor Changing Neutral Current process from strange to down quarks and its observation is new evidence for direct CP violation. Its irreducible theoretical uncertainty is very small and the decay is considered an ideal place to test the Standard Model and explore signs of new physics in quark flavor physics. KEK-PS E391a, performed at the KEK...

52. $K_L^0 \to \pi^0 \nu \overline{\nu}$ Experiment at J-PARC

Dr Hiroaki Watanabe (KEK)

25/05/2007, 12:20

Rare decays

J-PARC (Japan Proton Accelerator Research Complex), which intends to provide MW-class super-intense proton beam, is under construction. First slow-beam extraction at 30 GeV is scheduled on December, 2008. J-PARC-E14 experiment aims at first observation of the rare decay $K_L^0 \to \pi^0 \nu \overline{\nu}$ using intense $K_L^0$ beam. E14 reuses most of the detector and beam-line...

53. A proposal to measure the rare decay $K_L /rightarrow /pi^0 /nu /nubar$ at IHEP (Protvino) 70 GeV proton accelerator

Prof. Vladimir Bolotov (Institute for Nuclear Research of RAS)

25/05/2007, 12:40

Rare decays

The talk is supposed to be an extended description of the experimental setup KLOD, a joint project of IHEP (Protvino), INR (Moscow), JINR (Dubna). Some prospects related to this project have been preliminary reported at K-Rare2005 Workshop, Frascati. Presented at Kaon-2007 results are based on the Proposal of the experiment prepared to be published at IHEP. All experimental aspects...
