About
My research focuses on the theory and phenomenology of elementary particle physics and cosmology beyond the Standard Model, including supersymmetry, extra dimensions, and technicolor, along with their connections to Dark Matter.
See the list of my publications: theoretical papers and experimental papers.
Additionally, see a list of some available projects for PhD students.
For more details, please visit my personal website.
Building on my previous studies of various supersymmetric models, I have expanded my exploration to other theories that explain Dark Matter phenomena, including extra-dimensional theories and those involving dynamical symmetry breaking, such as Technicolor. I am also leading a project that connects collider and cosmological exploration of various Dark Matter models, which I believe will establish a solid foundation for uncovering the underlying theory.
In 2021, I co-authored The Basics of Nuclear and Particle Physics with Prof. Douglas Ross, a textbook aimed at advancing students' knowledge of nuclear and particle physics for third- and fourth-year undergraduate students.
A few additional details about my background.
I has been working in close contact with experimental collaborations: I am the former member of DØ collaboration at Fermilab (1996-2004) and presently I am the full member of the CMS collaboration at CERN since 2007.
I am one of three developers of the CalcHEP package which was created to enable one to go directly from the Lagrangian to the cross sections and distributions effectively, with a high level of automation. The package can be compiled on any Unix platform.
In 2011 I have pioneered High Energy Physics Model Database (HEPMDB) project which was created to facilitate connection between High Energy theory and experiment, and it is a tool to store and validate theoretical models. The goal is to provide a dictionary of model signatures, cutting down calculation times thus enhancing productivity within the field of Particle Physics.

Biography
Professor Alexander Belyaev is a theoretical physicist specialising in Beyond the Standard Model (BSM) physics, collider phenomenology, and dark matter studies. He is a Professor of Physics and Astronomy at the University of Southampton, where he has been a faculty member since 2007.
He graduated from Moscow State University in 1993 and obtained his PhD there in 1996. He began his research career at the Skobeltsyn Nuclear Physics Institute, later becoming a visiting researcher with the Fermilab DØ collaboration. He went on to hold research positions at leading institutions, including the Instituto de Física Teórica (UNESP), CERN’s Theory Division, Florida State University, and Michigan State University.
His research focuses on the theory and phenomenology of elementary particle physics and cosmology beyond the Standard Model, including supersymmetry, extra dimensions, and technicolor, as well as their connections to dark matter. He has worked closely with experimental collaborations, being a former member of the DØ collaboration at Fermilab (1996–2004) and a full member of the CMS collaboration at CERN since 2007.
Alexander is one of the three developers of the CalcHEP package, a computational tool designed to streamline the transition from Lagrangians to cross-sections and distributions with a high level of automation. In 2011, he pioneered the High Energy Physics Model Database (HEPMDB), a framework for collecting and exploring BSM models, which serves as a bridge between theoretical model building and experimental verification by providing a dictionary of model signatures and reducing computational overhead.
At Southampton, he has led multiple research projects in BSM physics, including recent studies of the vector-like fermionic portal, which connects the dark SU(2) sector to SM. His work also explores the potential astrophysical implications of a scale-dependent cosmological constant (Λ).
He has received substantial research funding and has published extensively in high-impact journals. He co-authored The Basics of Nuclear and Particle Physics, published by Springer, and remains actively engaged in advancing computational and phenomenological techniques in high-energy physics.
