Abstract
In these lectures, I will provide a brief pedagogical introduction into the structure and non-perturbative dynamics of confining gauge theories. Their implications for physics of dark sectors in the early Universe, with the focus on Dark Matter and its role in the cosmological history, will be overviewed. Furthermore, the properties of composite Dark Matter candidates – dark glueballs – naturally emerging in the context of confining pure Yang-Mills theories will be discussed, along with the possible ultraviolet scenarios for visible-to-dark portal interactions. Finally, we will look into attractive prospects for direct detection of such compound states via specific processes involving various portals, and their basic implications for the ongoing and future measurements will be outlined.
Biography
Roman Pasechnik is Associate Professor of Theoretical Physics at Lund University (Sweden, since 2015). Born in 1983, he earned his Ph.D. at JINR (Russia, 2009) and his habilitation at Lund (2014). With 160 peer-reviewed publications (h-index 31), his research spans Higgs physics, dark matter, QCD, models for New Physics and early-Universe gravitational waves and their cosmological implications. He has held Humboldt and Trygger fellowships and visiting professorships in Czechia, Brazil, and Chile. Leading an international team, he discovered the Odderon and proposed minimal Higgs–lepton unification. He teaches quantum field theory and cosmology, serves on editorial boards (Frontiers, Universe), and participates in LISA, SKA, and has represented Sweden on ECFA and C11 IUPAP commission.
