Theory of muonic versus electronic hydrogen Lamb shift
The significant discrepancy between theoretical predictions and the experimental result for the muonic hydrogen by the PSI collaboration questions the basis of QED theory of simple atomic systems. The discrepancy, in terms of the proton charge radius, being of the order of 5%, can not be explained by a mistake in the calculations, because they have been independly verified. It can not be explained by higher order QED corrections because they are orders of magnitude too small, and it can not be explained by a complicated internal structure of the proton, because the proton structure correction can be estimated from the inelastic electron-proton scattering and is 20 times too small. Finally, any exotic type of interactions at this levels of accuracy is ruled out by the muon g-2 measurement. In my talk I will present the QED theory of the muonic hydrogen in comparison to that of the electronic one and critically review solutions of the muonic hydrogen puzzle proposed in the literature.

Dimension-Six Terms in the Standard Model Lagrangian
When the Standard Model is considered as an effective low-energy theory, higher dimensional interaction terms appear in the Lagrangian. Dimension-six terms have been enumerated in the classical article by Buchmüller and Wyler. Although redundance of some of those operators has been already noted in the literature, no updated complete list has been published to date. I am going to present results of the classification that has been done once again from the outset and led to a considerable reduction of the mentioned list.

Neutrino Physics
This will be a very (!) elementary review of the research in the area of neutrino physics. The review will include the discussion of the current knowledge about oscillation parameters and information about various (often very interesting) neutrino sources. Recent oscillation measurements from MiniBooNE and MINOS experiments (both with antineutrino fluxes) will be presented. Both of them can point to physics going beyond the Standard Model.
