        The Strong CP Problem and Axions 1h 30m

        Outline of the lecture:

        In this lecture I will explain the origin of the Strong CP Problem, which is connected to the non- trivial structure of the vacuum state of the Standard Model. The most natural solution to this problem involves introducing an additional global chiral U(1) symmetry in the theory. Because this symmetry is both spontaneously broken and anomalous, this solution necessitates the presence of a very light, very weakly coupled boson, known as the axion. Physical properties of axions, including their mixing with pions and etas and their coupling to two-photons are described. Using these results, it is possible to rule out weak-scale axions. However, invisible axions models are still viable. Some of the properties of these latter models will be also discussed.

        Electric and Magnetic Dipole Moments 1h 30m

        Outline of the lecture:

        The stringent limit on the electric dipole moment of the neutron forced the issue on the strong CP-problem. The most elegant solution of which is the axion field proposed by Peccei and Quinn. The current limit on the QCD parameter theta coming from the limit on the neutron EDM is of order 10-10. I am going to describe the present status on the neutron EDM searches and further prospects on getting down to theta_qcd sensitivity of 10-13 with the new deuteron EDM in storage rings proposal. For completeness the current status and prospects of the muon g-2 experiment will also be given.

        Cavity Microwave Searches for Cosmological Axions 1h 30m

        Outline of the lecture:

        The lecture will cover the searches for dark matter axions based on the microwave cavity experiment of Sikivie. The topics will begin with a brief overview of halo dark matter, and the axion as a candidate. The principle of resonant conversion of axions in an external magnetic field will be described, and practical considerations in optimizing the experiment as a signal-to-noise problem. A major focus of the lecture will be the two complementary strategies for ultra-low noise detection of the microwave photons - the "photon-as-wave" approach (i.e. conventional heterojunction amplifiers and soon quantum-limited SQUID devices), and "photon-as-particle" (i.e. Rydberg-atom single-quantum detection). Experimental results will be presented; these experiments have already reached well into the range of sensitivity to exclude plausible axion models, for limited ranges of mass. The lecture will conclude with a discussion of future plans and challenges for the microwave cavity experiment.

        Axions and Their Relatives 1h 30m

        Outline of the lecture:

        A summary of the status of axions and axion-like particles will be given. Special attention is devoted to the recent results of the PVLAS collaboration, which are in conflict with CAST data and with astrophysical constraints. Solutions to this puzzle and the implications for new physics are dicussed. The subject of axion-like particles as dark matter will be included in the lecture. Finally some new results on new forces mediated by light scalars are debated.
