Why Are We Here? Matter-Antimatter Asymmetry Of The Universe

Promotional image for talk: Elements of a successful scientific talk

Speaker(s): Seyda Ipek

Everything around us, cookies, rocks, stars, galaxies, etc. is made up of “matter” and not “antimatter”. We know that if antimatter comes close to matter, they annihilate each other leaving only energy behind. That we are here means there is no antimatter to annihilate with us. But what happened to the antimatter in the Universe? Where did it go? How did it disappear? Why/how did matter stay behind? I will talk about this mystery and possible ways around it which requires new physics beyond the Standard Model of particle physics.

Colloquium

Junior and senior physics majors attend our biweekly colloquium series, held on Tuesday afternoons at 4:30 p.m. in Shanahan B460. The talks are open to all students and to the public, and are frequently attended by scientists from the other Claremont Colleges, Cal Poly Pomona, and others. The series features speakers from a broad range of institutions and fields of physics.
