Riasat Sheikh
PhD Researcher
I’m a PhD researcher in elementary particle theory, working on dark matter models, particle phenomenology, and exploring new ideas beyond the Standard Model. My work is driven by a curiosity to understand the universe at its most fundamental level.
Any inquiries, collaboration opportunities, or discussions related to my research are welcome. Feel free to reach out.

Pseudo-Nambu-Goldstone-boson Dark Matter from Three Complex Scalars
This study explores a dark matter model in which a pseudo-Nambu-Goldstone boson arises as a viable dark matter candidate from the spontaneous and soft breaking of global $\mathrm U(1)$ symmetries and stabilized by a residual $\mathbb{Z}_3$ discrete symmetry. The model introduces three complex scalar …
