3. Theory Prediction of epsilon_K

Dr Joachim Brod (Excellence Cluster Universe, TU München)

T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

The parameter epsilon_K plays an important role in the phenomenology of the Standard Model and its extensions. It is very sensitive to high-energy scales and can be predicted with remarkable precision. In this talk I will give a summary of the theory prediction and present our recent NNLO QCD calculation of the short-distance contributions to epsilon_K in the Standard Model.

5. CP tests at NA48

T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

We report on measurements of the rare decays K+- -> pi+- e+ e- and K+- -> pi+- mu+ mu-. The full NA48/2 data set was analyzed, leading to more than 7200 reconstructed events in the electronic and more than 3000 events in the muonic channel, the latter exceeding the total existing statistics by a factor of five. For both channels the selected events are almost background-free. From these...

42. K --> pi nu nu : Standard Model Prediction and New Physics

Mr Emmanuel Stamou (Technical University Munich)

06/12/2010, 15:40

T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

Promising future experiments and precise theoretical calculations promote the $K^+\rightarrow \pi^+\nu\bar\nu$ and $K_L\rightarrow \pi^0\nu\bar\nu$ decays to probes of high energy phenomena. Both modes are sensitive to much higher energy regimes than those accessible with present day colliders. In this talk I shall review the current theoretical prediction within the Standard Model (SM)...

79. Tests of the Fundamental Symmetries in the η Meson Decays

Dr Andrzej Kupsc (Uppsala University)

T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

Patterns of isospin violation and tests of conservation of the fundamental C, P and CP symmetries are the key physics issues in studies of pi0 , eta and eta ′ decays. The tests of the fundamental symmetries include searches for rare or forbidden decays and searches for asymmetries among the decay products in the not–so–rare decays. Some examples of the searches for the rare decays are eta->...
