General Solutions to Gauge Anomaly Equations
Date: Tuesday, November 2nd
Time: 4:00 pm - 5:00 pm
Place: Chamberlin 5280
Speaker: Bogdan Dobrescu, Fermilab
Abstract: A long-standing problem in particle physics is how to identify anomaly-free sets of chiral fermions charged under one or more U(1) gauge symmetries. I will present the general solution to the anomaly equations for any number of fermions charged under a single U(1). Then I will discuss the general solution for six fermions charged under a U(1)XU(1) gauge group, and give an example of a dark matter model based on that solution. Finally, in U(1) extensions of the Standard Model, I will derive the general set of charges for three right-handed neutrinos.
