Intensive Course on Theory and Phenomenology of Beyond the Standard Model frameworks
The course suits both experimentally and theoretically oriented particle physics students and also cosmology students. Many of the topics discussed on the course are researched in University of Helsinki and PAPU doctoral school.
Scalar extensions are the most well-motivated frameworks beyond the Standard Model (BSM). These scenarios provide solutions to many of the shortcomings of the Standard Model (SM), such as lack of a viable Dark Matter candidate, an explanation for the fermion mass hierarchy and the matter-antimatter asymmetry observed in the universe. This course will cover the singlet and doublet scalar extensions of the SM and how such scenarios resolve the issues that SM leaves unanswered.
Neutrinos and sterile neutrinos are of a significant importance in most BSM theories. The course provides insight on neutrino sector within and beyond the Standard Model and neutrino mass and oscillation in three-neutrino and extended frameworks.
Knowledge of various analytical and numerical tools is essential to perform phenomenological studies, i.e., to extract predictions of possible experimental signatures of a BSM scenario or to study its compatibility with existing experimental results. This course will introduce the methodology for collider phenomenological studies applicable to any generic BSM scenario.

The course has three distinct parts:
• Part I: Scalar extensions
• Part II: Neutrino mass and oscillations
• Part III: Collider physics and BSM phenomenology software
BSM physics is a subfield of particle physics under active study, aiming to elucidate a large amount of unsolved problems in particle physics, namely
• Amount of CP violation
• Electroweak baryogenesis and seesaw leptogenesis
• Origin and nature of neutrino mass
• Are there sterile neutrinos, axions, heavy scalars, new gauge symmetries, flavour symmetries, long-lived particles or new fundamental forces?
BSM phenomenology is heavily computerized, and the knowledge of state-of-the-art software libraries is essential to perform predictive analyses, starting with implementation of the model to performing simulation using a number of tools, namely, SARAH, SPHENO, MADGRAPH, PYTHIA, DELPHES and MADANALYSIS.
