Investigating the Glue that Binds Us All: The Electron-Ion Collider

<strong>Seminar of the School of Physical Sciences -------------------------------------------------</strong> Title: <strong>Investigating the Glue that Binds Us All: The Electron-Ion Collider</strong> Speaker: <strong>Tobias Toll </strong> (Shiv Nadar University, Gautam Buddha Nagar)) Date: <strong>April 27, 2016</strong> <strong>Abstract:</strong> The Standard Model of Particle Physics is one of the most successful theories about nature in history. One part of the Standard Model is the Strong Force, which binds quarks together in protons and neutrons, and make them form atomic nuclei. The gluon, which is the mediator of the strong force, is believed to contribute to 95% of the mass of the visible universe. Yet, the Strong Force, is still not very well understood. The Electron-Ion Collider (EIC), which will be built in the US, will be a very high precision femtoscope which will probe the innards of protons and heavy nuclei. In my talk I will describe how the EIC will be able to shed light on the two main puzzles of the strong force: How gluons behave in extremely dense systems, and how they contribute to the spin of the proton.
