Hidden interactions of quarks

The quarks feel all five types of boson-mediated interactions: electromagnetic, strong, weak, Higgs and gravitational. In this talk I will discuss theoretical and experimental constraints on hypothetical new interactions among quarks. Interactions of this type can be hidden if they have a very short range, or if they are very weak, or by other mechanisms such as momentum-dependent couplings. A related question is how strongly can quarks interact with dark matter.

Refreshments will be served in CP 179 at 3:15 PM
