Experimental Particle Physics

Center for Astrophysics and Cosmology is also involved in a collaboration with the Japanese Organization for Accelerator Research (KEK) since 1999 where, within the framework of Belle and Belle2 collaborations, we are investigating the differences between properties of particles and anti-particles called B mesons. Our results indicate a discrepancy between measured and theoretically predicted values of the so called CP asymmetry, which may be due to the existence of additional, yet undiscovered CP violating processes not present in the Standard model of elementary particle physics. The search for such processes is crucial for the understanding of the evolution of the universe and its current properties.
