11th Symmetry Webinar

Hidden Dark Sector in High Energy Physics

Dear all, the MDPI Symmetry webinar on the “Hidden Dark Sector in High Energy Physics” will discuss topics from high energy physics based on some selected articles published in the Symmetry Special Issue (SI) with the same title.

The Standard Model (SM), while extremely powerful as a description of strong, electromagnetic and weak interactions, is not a natural candidate to explain dark matter. Theoretical and experimental motivations exist for the existence of a hidden or dark sector of phenomena that couples either weakly or in a special way to SM fields. Hidden sectors near the weak scale are motivated by naturalness, thermal dark matter and electroweak baryogenesis but also represent a generic expectation for physics beyond the SM (BSM). If there is such a family of particles and interactions, they may be accessible experimentally at the Large Hadron Collider (LHC) at CERN and at future high energy colliders. As a prototypical hidden sector can be considered, there is the compelling possibility of an exact or spontaneously broken U(1) dark gauge symmetry, mediated by a vector boson called the dark photon. The search for such a hidden sector is an important component of the LHC physics program. The LHC provides a unique tool to explore such models where these new states can be produced using, for example, exotic Higgs boson decays to light scalars or light vectors and inclusive dark photon decays or associated productions as a portal to this hidden or dark sector, which has remained inaccessible up to now.

Andrei Afanasev currently leads the physics effort for the GWU energy initiative. He has made significant research contributions in the field of nuclear and particle physics probed with high-power electron accelerators and free-electron lasers. Presently Prof. Afanasev contributes to energy research in three areas: (a) High-power particle accelerators that may serve as drivers for accelerator-driven subcritical nuclear reactors (ADSR), as well as probes of new materials for energy applications; (b) Development of novel techniques in photovoltaics, including nanostructures, quantum dots, and surface acoustic waves; (c) New technologies for non-proliferation of nuclear materials. Prof. Afanasev is the Director of the Photoemission Research Laboratory where new solutions for particle accelerator sources and photovoltaics are being developed and tested.
