Probing Cosmic Inflation and Quantum Gravity with the LiteBIRD CMB Polarization Survey

Wednesday 23.11.2022, 11.00 AM



LiteBIRD is a space mission for primordial cosmology and fundamental physics. The Japan Aerospace Exploration Agency (JAXA) selected LiteBIRD as a strategic large-class (L-class) mission, with an expected launch in the late 2020s using JAXA's H3 rocket. LiteBIRD is planned to orbit the Sun-Earth Lagrangian point L2, where it will map the cosmic microwave background (CMB) polarization over the entire sky for three years. The primary scientific objective of LiteBIRD is to search for the signal from cosmic inflation, either making a discovery or ruling out well-motivated inflationary models. The measurements of LiteBIRD will also provide us with insight into the quantum nature of gravity and other new physics beyond the standard models of particle physics and cosmology. The LiteBIRD collaboration is international with a lot of members from Europe. In this talk, I provide an overview of the LiteBIRD project.

Our speaker is KEK Professor, Kavli IPMU Professor at the University of Tokyo, JAXA Professor and Professor at the Sokendai University.

Masashi Hazumi obtained PhD at Tokyo University for his work on the electron-proton physics in the ZEUS experiment at HERA in Hamburg. Then, for about 10 years he did research in the electron-positron physics with the Belle detector at KEKB in Tsukuba, but graduallydeveloped also deep interests in the superconducting detectors.

In 2007 prof. Hazumi jumped into science of the Cosmic MicrowaveBackground (CMB): "Current status and future plans of a new experimental cosmology group at KEK are reviewed. The group was formed in December 2007". He became Principal Investigator of the LiteBIRD mission and since December 2021 has been first director of the new International Center for Quantum-field Measurement Systems for Studies of the Universe and Particles (QUP).
