Contribution

It provides a concise summary of the status and potential of a fourth generation in particle physics, emphasizing recent experimental and theoretical considerations.

Findings

Fourth generation not excluded by EW data

It can address open questions in physics

LHC can discover or exclude it

Abstract

This summary of the Workshop "Beyond the 3-generation SM in the LHC era" presents a brief discussion of the following four statements about the fourth generation: 1) It is not excluded by EW precision data; 2) It addresses some of the currently open questions; 3) It can accommodate emerging possible hints of new physics; 4) LHC has the potential to discover or fully exclude it.
