THEORETICAL PARTICLE PHYSICS AND COSMOLOGY

Entry requirements:

•  Master’s degree / equivalent in a related field
•  B2 level of English
•  Good track record of publications related to the topic of the intended research
•  Strong research proposal 1,500 - 3,500 words

Research supervisor:
Dmitry Gorbunov
PhD, DSc

Supervisor’s research interests:
Quantum field theory, physics beyond the Standard Model of particle physics (supersymmetry, grand unification, hidden sectors and portals, etc.), neutrino physics, astroparticle physics and cosmology (dark matter models, inflation and reheating, baryogenesis).

Research highlights:
Typically, the group members participate in 2-3 projects supported by Scientific Foundations. There are also special prizes and awards for PhD students from the Institute for Nuclear Research. The group has scientific relations (collaborations, visits, etc) with theory divisions of EPFL (Lausanne), Manchester University, ULB (Brussels), ETH (Zurich), Munich University, Prague University.

Supervisor’s specific requirements:

•  Quantum field theory (e.g. Peskin & Scroeder).
•  Classical Theory of Gauge Fields (e.g. Rubakov).
•  Standard Model of particle physics (symmetries, strong and electroweak interactions, Higgs mechanism, etc, e,g, Okun).
•  Math: calculus, differential and integral equations, Group Theory, matrix theory.
