In the pursuit of the Neutrino
Lecture 1: In pursuit of the neutrino: where are we now and how did we get here This lecture provides an overview of the history of neutrinos up until approximately 2005. It sets the stage to discuss the current issues in neutrino physics that will be discussed in lecture 2.
Lecture 2: In pursuit of the neutino: the big questions and efforts to find answers This lecture summarizes the current paradigm in neutrino physics, lays out the main questions and areas of investigation along with a bit of experimenters phenomenology. In addition, some recent experimental results and their implications will be discussed.

Double beta decay: Status and perspectives
In these lectures I will briefly review the motivation and history of double beta decay search since the first consideration of two neutrino process (2(2)) by Maria Goeppert-Mayer in 1935. The first experiments on search for double beta decay in the late 1940’s and beginning of 1950’s are considered. It is underlined that for the first time the 2(2) decay has been registered in geochemical experiment with 130Те in 1950. In direct (counter) experiment this type of decay for the first time has been registered in 82Se by Michael Moe's group in 1987. Now two neutrino double beta decay has been recorded for 11 nuclei (48Ca, 76Ge, 82Se, 96Zr, 100Mo, 116Cd, 128Te, 130Te, 136Xe, 150Nd, 238U). In addition, the 2(2) decay of 100Мо and 150Nd to the 0+1 excited state of the daughter nucleus has been observed and the 2К(2) process in 130Ва was observed. As to neutrinoless double beta decay (2(0)) this process has not yet been registered. In the review results of the most sensitive last and modern experiments (Heidelberg-Moscow, IGEX, CUORICINO, NEMO-3) are discussed and conservative upper limits on effective Majorana neutrino mass and the coupling constant of the Majoron to the neutrino are established as <m> <0.75 eV and <gee> < 1.9·10-4, respectively.
The next-generation experiments, where the mass of the isotopes being studied will be as grand as 100 to 1000 kg, are discussed. It is expected that they will reach sensitivity to the neutrino mass at a level of 0.01 to 0.1 eV

QCD in an external magnetic field
Strong magnetic fields are produced in heavy ion collisions, and are
believed to exist inside the neutron stars. The interplay of topology of non-Abelian
gauge theories and an external (Abelian) magnetic field leads to a number of surprising
effects, including the Chiral Magnetic Effect. Relativistic hydrodynamics has to be

Indirect probes of new physics: Concepts and application of effective field theories.
Effective field theories (EFTs) provide the modern tool to study physics problems involving several distinct length scales. They describe the physics at a given energy scale in terms of effective operators involving the low-energy modes of the theory, multiplied by Wilson coefficients encoding the short-distance quantum effect due to virtual particles. As such, EFTs give us a tool to systematically probe for effects of "new physics" (such as new heavy particles or new interactions) via high-precision studied of low-energy observables. In this course, we will discuss the basic principles of EFTs in general, and then study some specific applications relevant to modern particle physics including the Higgs search at the LHC.
