Abstract: We describe our solution to the Banff 2 challenge problems as well as the outcomes.
Cosmic acceleration and the challenge of modifying gravity
Cosmic acceleration modifying gravity

briefly discuss the challenges presented by attempting to modify general relativity to obtain an explanation for the observed accelerated expansion of the universe. Foremost among these are the quest...
Massive Degeneracy and Goldstone Bosons: A Challenge for the Light Cone
Massive Degeneracy Goldstone Bosons the Light Cone
2010/12/23
Wherein it is argued that the light front formalism has problems dealing with Goldstone symmetries. It is further argued that the notion that in hadron condensates can explain Goldstone phenomena is f...
Quadrupole Moments of Collective Structures at Ultrahigh Spin in $^{157}$Er and $^{158}$Er: A Challenge for Understanding Triaxiality in Nuclei
Quadrupole Moments Collective Structures Ultrahigh Spin $^{157}$Er and $^{158}$Er Challenge Understanding Triaxiality Nuclei
2011/1/4
Measured transition quadrupole moments, $Q_{\rm t}{\sim}11 {\rm eb}$, of four weakly-populated collective bands at ultrahigh spin in $^{157,158}$Er demonstrate that these sequences are associated with...
Absorption and Emission in the Non-Poisson Case: The Theoretical Challenge Posed by Renewal Aging
