Abstract

Axion-like particles (ALPs) are hypothetical particles that have garnered significant attention in both particle physics and cosmology due to their potential roles in addressing unresolved issues such as the strong CP problem, dark matter, and dark energy. This paper provides a comprehensive overview of ALPs, starting with their theoretical foundations and production mechanisms in the early universe. The paper will explore their interactions with standard model (SM) particles and their influence on cosmological phenomena, including Big Bang nucleosynthesis, the cosmic microwave background, and structure formation. Furthermore, the paper will examine the viability of ALPs as dark matter candidates and their potential contributions to the dynamics of dark energy. Current experimental efforts, including direct detection methods like haloscopes and helioscopes, along with indirect detection strategies through astrophysical observations, are reviewed. The challenges and open questions in ALP research are discussed, highlighting the need for future theoretical and experimental advancements to unveil the mysteries surrounding these elusive particles.
