TASI Lectures on Remnants from the String Landscape

Superstring theories are very promising theoretically, but the enormous landscape of string vacua and the (likely) very large underlying string scale imply that they may never be tested directly. Nevertheless, concrete constructions consistent with the observed world frequently lead to observable remnants, i.e., new particles or features that are apparently accidental consequences of the ultraviolet theory and that are typically not motivated by specific shortcomings of the standard models of particle physics or cosmology. For example, moduli, axions, large extended gauge sectors, additional $…

The Nightmare Scenario and the Origin of the Standard Model. "We Got it Wrong ...How did we misread the signals? ... What to Do?"

It is thought that the emergence of the "nightmare scenario" at the LHC could be a serious crisis for particle physics that could require radical new concepts and even a major paradigm change. A root cause may have been exaggeration of the significance of asymptotic freedom, leading to the historically profound mistake of formulating new short-distance extensions of the Standard Model while ignoring both serious infra-red problems and central elements of long-distance physics. In fact, pursuit of the uniquely unitary Critical Pomeron leads to a possible gauge theory origin for the Standard Mod…
