A new class of collective excitations of the Hubbard model I: excitation of the negative-- model

Eugene Demler, Shou-Cheng Zhang, Nejat Bulut +1

In this series of papers we present a detailed study of the particle--particle collective excitations of the Hubbard model, and their contribution to the density and spin excitatio…

The Generalized Crewther Relation in QCD and its Experimental Consequences

S. J. Brodsky, G. T. Gabadadze, A. L. Kataev +1

We use the BLM scale-fixing prescription to derive a renormalization-scheme invariant relation between the coefficient function for the Bjorken sum rule for polarized deep inelasti…

Weak Decays Beyond Leading Logarithms

Gerhard Buchalla, Andrzej J. Buras, Markus E. Lautenbacher

We review the present status of QCD corrections to weak decays beyond the leading logarithmic approximation including particle-antiparticle mixing and rare and CP violating decays.…

The Physics Inside Topological Quantum Field Theories

Roger Brooks

We show that the equations of motion defined over a specific field space are realizable as operator conditions in the physical sector of a generalized Floer theory defined over tha…

Connected sum constructions for constant scalar curvature metrics

Rafe Mazzeo, Daniel Pollack, Karen Uhlenbeck

We give a general procedure for gluing together possibly noncompact manifolds of constant scalar curvature which satisfy an extra nondegeneracy hypothesis. Our aim is to provide a…

Decision-Theoretic Foundations for Causal Reasoning

D. Heckerman, R. Shachter

We present a definition of cause and effect in terms of decision-theoretic primitives and thereby provide a principled foundation for causal reasoning. Our definition departs from…
