Physics Colloquium

Gumaro Rendón, Ph.D., of Brookhaven National Lab, will present, “New Physics on the Lattice.”

The success the Standard Model (SM) has had in describing particle physics cannot be overstated. It describes the smallest constituents of matter as well as three of the four fundamental forces—weak nuclear, strong nuclear, and electromagnetic—that hold these together. After the discovery of the Higgs boson, we have observed, directly or indirectly, all the particles in the model. However, its shortcomings should not be disregarded. There are several phenomena observed experimentally that cannot be described within it.

For instance, deviations between experiment and SM predictions have emerged in weak nuclear processes. However, the enveloping strong nuclear interactions have to first be calculated. We discuss how we use a space-time lattice to accomplish this.
