Axions are hypothetical particles arising in models which may solve the CP problem of strong interactions. They are practically stable neutral pseudoscalar particles and also viable candidates for the dark matter in the universe.
Most of the axion experimental searches are based on the axion coupling to two photons. As a consequence of this coupling, axion could transform into photon and vice...

Since Spring 2010 the CMS experiment has recorded about 3 pb-1 of proton-proton collision data at a centre-of-mass energy of 7 TeV, and a substantial increase is expected until the end of the year. In this talk first results on Standard Model physics obtained in this new energy domain will be presented, demonstrating the outstanding performance of the CMS detector. First examples of BSM search...

Observations of the Cosmic Microwave Background anisotropies have led over the last decade to spectacular results concerning the cosmological model describing our Universe. The specific angular scales of the temperature and polarization anisotropies, along with other cosmological probes, have allowed for an accurate measurement of the cosmological parameters leading to the LambdaCDM model. All...

The Q/U Imaging ExperimenT (QUIET) is a ground-based radiometer array
designed to measure the polarization of the Cosmic Microwave Background (CMB)
radiation. The polarization of the CMB can be decomposed into a curl-free component, or E-modes, and divergence-free component, or B-modes. Previous observations for the E-modes as well as temperature anisotropy of the CMB have been used to...

We analyse CMB data in a manner which is as model-independent as possible.
We encode the effects of late-time cosmology into a single parameter which
describes the distance to the last scattering surface, similar to the shift parameter, and exclude low multipoles, up to l 40 from the analysis. We consider the WMAP five-year as well as ACBAR 2008 observations. We obtain constraints on...

After introducing the notion of asymptotic safety I will briefly discuss the existing theoretical evidence for this behavior in the case of gravity, and possible appplications to inflationary cosmology.

Probed at small scales, spacetime appears to be very complicated - something akin in complexity to a turbulent froth which John Wheeler dubbed spacetime foam. I will give an elementary discussion of my recent work on spacetime foam and the cosmology (dark energy and dark matter) inspired by it.

In my talk I will present DLCQ procedure and explain how it can be generalized to some special IIA backgrounds, Singular Homogeneous Plane-Waves. These space-times can be seen as Penrose limits of a very large class of metrics, including the Friedmann-Robertson-Walker cosmological model, so a non-perturbative string theory model such as that provided by DLCQ can hopefully teach us something...

The Pierre Auger Observatory was designed to make precise measurements of cosmic ray air showers induced by the highest energy cosmic particles. The aparatus consists of about 1600 water Cherenkov tanks distributed over an area of some 3000 square kilometers, all of which are overlooked by 24 fluorescence telescopes. The instrument has already provided us with the most detailed energy spectrum...

The talk will review some highlights of measurements of B and D meson properties in experiments at B factories, with emphasis on the time evolution of the systems and CP violation. We will further discuss the motivation for a future Super B factory, as well as the requirements for the detector and for the accelerator. Finally, the present status of the project will be presented together with...

Precise measurements of CP and CPT symmetry based on the full dataset of K -> pi pi decays collected by the KTeV experiment at Fermi National Accelerator Laboratory during 1996, 1997, and 1999 are presented. The direct CP violation parameter Real(epsilon'/epsilon) is determined to 10% accuracy: Real(epsilon'/epsilon)=(19.2 \pm 2.1)x10^{-4}. Several parameters that test CPT invariance are...

One of the mysteries of our universe is the observed baryon asymmetry which can not be explained using the Standard Model of particle physics. According to Sacharov this implies further, yet unknown, CP violation which will be tested with a refined search for the neutron electric dipole moment. A collaboration of 15 European institutes has been preparing a more sensitive experiment to be...

We study a holographic description of the region behind a black hole horizon using the AdS/CFT correspondence. In particular we discuss the relationship between gauge theory observables adapted to external and infalling bulk observers, and the relationship between physics near the horizon and near the singularity Using D-brane probes we find some sharp signatures of the singularity.

We explore in detail inflationary models where the inflaton is an axion whose potential is generated by the mixing with topological $4$-forms. The mixing-generated inflaton mass term is radiatively protected by a shift symmetry, that is only broken weakly by nonperturbative effects and/or background flux values. Such mechanisms are very similar to monodromy inflation, and may naturally emerge...

Here I show that a classical or a quantum bit state plus one simple operation, a flipping action, are sufficient ingredients to derive a quantum dynamical equation that rules the sequential changes of the state. Uniformity of time arises due to the composition rule of the actions. Then, by assuming that a freely moving massive particle is the qubit carrier, it is found that both, the particle...

We study the potential of the international linear collider (ILC) at √s=500 GeV to probe new dark matter motivated scenario where the bottom squark (sbottom) is the next-to-lightest supersymmetric particle. For this scenario, which is virtually impossible for the LHC to test, the ILC has a potential to cover a large fraction of the parameter space. The challenge is due to a very low energy of...

In this talk the physical foundations for setting up the cosmological standard model with a cosmic time parameter are examined. In particular, I discuss the role of Weyl’s principle which asserts that cosmic matter moves according to certain regularity requirements. I argue that although Weyl’s principle is often not explicitly mentioned in modern standard texts on cosmology, it is in fact...

The opposition between Einstein and Bohr has been often described as the opposition between an epistemological and an ontological approach towards quantum mechanics. Although both frameworks (ontological and epistemological) have been later recognized as supplementary rather than contradictory, they have stayed more or less isolated from one another. An interesting possibility for exceeding...
