- SUSY strikes back: there is no crisis for SUSY but a new collider may be required for discovery
- Time: 3:00 pm - 4:00 pm
- Place: 5280 Chamberlin Hall
- Speaker: Howard Baer, University of Oklahoma
- Abstract: Many authors have proclaimed a crisis state for SUSY due to the growing gap between the weak scale as typified by the Z and h mass, and the SUSY breaking scale which now sits in the mid-TeV range. This is the so-called Little Hierarchy. Vernon and I argue that the 'crisis' arises due to mis-calculation of electroweak fine-tuning and failure to combine dependent terms. The large log measure neglects the H_u soft mass while Barbieri-Giudice is typically applied to effective theories instead of supergravity. When these measures are rectified, they agree with the EW fine-tuning measure and predict light higgsinos which are hard to see at LHC but would be clear at an ILC. Extending naturalness to the QCD sector, we expect dark matter to consist of an axion-higgsino admixture: i.e. two dark matter particles.

- Spontaneously broken supersymmetries in string compactifications
- Time: 4:00 pm - 5:00 pm
- Place: 5280 Chamberlin Hall
- Speaker: Hagen Triendl, CERN
- Abstract: Supersymmetric compactifications of string and M-theory have been intensely studied over the last years. One of the major questions in this context is the appearance of perturbative and non-perturbative string corrections. In this talk I will explain that many of these compactifications admit additional, spontaneously broken supercharges that can explain the vanishing of certain perturbative string corrections and lead to conjectures for the vanishing of certain non-perturbative corrections. I will give concrete examples and show how they are related by dualities.
