Quantum Discrete Symmetry and the Strong CP Problem
Silas R. Beane
We study a 2N-flavor effective theory of N-flavor QCD. With the axial anomaly accounted for in the effective theory by a 't Hooft interaction, only QCD conserved currents survive.…
Flavor Doubling and the Nature of Asymptopia
Silas R. Beane
We consider the possibility that QCD with N flavors has a useful low-energy description with 2N flavors. Specifically, we investigate a free theory of 2N quarks. Although the free…
On the importance of testing gravity at distances less than 1cm
Silas R. Beane
If the mechanism responsible for the smallness of the vacuum energy is consistent with local quantum field theory, general arguments suggest the existence of at least one unobserve…
Novel Algebraic Consequences of Chiral Symmetry
Silas R. Beane
Phenomenologically motivated Lie-algebraic sum rules determine the representations of unbroken SU(2)_L X SU(2)_R filled out by mesons containing a single heavy quark, in the limit…
Neutral pion photoproduction on deuterium in baryon chiral perturbation theory to order q^4
S. R. Beane, V. Bernard, T. -S. H. Lee +2
Threshold neutral pion photoproduction on the deuteron is studied in the framework of baryon chiral perturbation theory beyond next-to--leading order in the chiral expansion. To fo…
