Connecting Cosmic Inflation to Particle Physics with LiteBIRD, CMB S4, EUCLID and SKA

Dr. Lei Ming (School of Physics, Sun Yat-Sen University, Guangzhou, China) will show that next generation CMB experiments will be capable of the first ever measurement of the inflaton coupling to other particles, opening a new window to probe the connection between cosmic inflation and particle physics. For his analysis he introduces a simple analytic method to estimate the sensitivity of future CMB observations to the reheating temperature and the inflaton coupling. This sensitivity is based on the impact that the reheating phase after cosmic inflation has on the redshifting of cosmic perturbations.
