This summary of the 3rd “Beyond the 3 Generation Standard Model” workshop
presents the following four statements (and their implications) for the ongoing
and future searches of a fourth generation:
- The enhancement of the Higgs gluon-gluon production cross-section times
branching fraction for many of the search channels studied at the Large Hadron
Collider (LHC) is not a flat factor of 9;
- Electroweak precision data allows for not only a fourth generation, even
more generations are allowed;
- Consideration of mixing significantly changes the conclusions about the
interpretation of experimental constraints, and even a fully-degenerate fourth
generation becomes allowed;
- The features that make a fourth generation of fermions attractive are
still valid even under the light of initial LHC results.
