Dr. Salman Habib (Los Alamos) - "Cosmology as an Inverse Problem"
Abstract: The current status of cosmology is more analogous to a fundamental phenomenology (e.g. condensed matter physics) rather than fundamental physics (e.g. particle physics). The accuracy of current and future cosmological observations is already stressing our theoretical ability to analyze data and to build an intuitive phenomenological picture. In this talk I'll discuss the world-view of cosmology as an inverse problem, discuss the associated problems, and point to certain statistical approaches and possible solutions.

Prof. Doug McKay (KU Physics & Astronomy) "New physics, the cosmic ray spectrum knee, and pp cross section measurements"
Abstract: We model new physics modifications to the total proton-proton cross section with an incoherent term that allows for missing energy above the scale of new physics. We explore the possibility that the new physics interaction alone can provide an explanation for the knee just above 106 GeV in the cosmic ray spectrum. We add the constraint that the new physics must also be consistent with published pp cross section measurements an order of magnitude and more above the knee. Allowing for the necessary rescaling of the cross section data in the light of the new physics, we find parameter ranges in several generic models that readily give good quality fits to recently published Tibet III spectrum analysis and to the rescaled direct cross section measurements. The rise in cross section required at energies above the knee is radical. Even before reaching design energy, the Large Hadron Collider can test this picture with total cross section measurements.
