Abstract
People have developed two standard models to understand our universe. One is the Standard Model of Particle Physics, which can be used to describe almost all the particle phenomena on Earth. The other is the Standard Model of Cosmology, describing the content and evolution of our universe. However, we see problems when we combine the two standard models. The Standard Model of Particle Physics fails to provide candidates for dark matter and dark energy, and cannot explain the baryon-anti-baryon asymmetry. Therefore, new physics beyond the Standard Model of Particle Physics must exist. My talk will focus on new ideas to search for new physics. My talk contains two parts. In the first part, I will discuss new ideas to search for the particle natures of dark matter. In the second part, I will discuss using gravitational waves to search for new particle physics with energy scales well beyond the Standard Model.
