| Description | Speaker: Yuhsin Tsai Title: Cosmological Particle Production and Pairwise Hotspots on the CMB Zoom: https://zoom.us/j/186024391 Host: Abstract: Cosmic inflation provides an environment similar to particle colliders that can produce new particles and record the resulting signals. In this talk, I will describe a scenario in which heavy particles are produced during inflation via their couplings to the inflaton. These heavy particles propagate classically and give rise to localized spots on the cosmic microwave background following their production. Momentum conservation during particle production dictates that these localized spots come in pairs. I will discuss the properties of such pairs of CMB spots and the prospect of their detection from the thermal fluctuation background in a position space search. |
