| Title: | Breakdown of the narrow width approximation |
| Speaker/Affiliation: | Dr. David Rainwater, University of Rochester |
| Description: | I demonstrate that the narrow width approximation, the most widely-used shortcut in collider physics calculations, ceases to be valid for multiple reasons in many new physics scenarios, none of which exist in the Standard Model. Using SUSY as an example, I show that collider physics processes can receive O(1) corrections, with impact on both kinematic and rate or branching ratio types of analyses. It is also possible for interference to fake new physics. This calls for a return to more complete leading-order calculations and development of the necessary tools.
