Continuum methods in lattice perturbation theory
Thomas Becher, Kirill Melnikov
We show how methods of continuum perturbation theory can be used to simplify perturbative lattice calculations. We use the technique of asymptotic expansions to expand lattice loop…
The Asymptotic Expansion of Lattice Loop Integrals Around the Continuum Limit
Thomas Becher, Kirill Melnikov
We present a method of computing any one-loop integral in lattice perturbation theory by systematically expanding around its continuum limit. At any order in the expansion in the l…
Baryon Chiral Dynamics
Thomas Becher
After contrasting the low energy effective theory for the baryon sector with one for the Goldstone sector, I use the example of pion nucleon scattering to discuss some of the progr…
Constraints on Light Bottom Squarks from Radiative B-Meson Decays
Thomas Becher, Stephan Braig, Matthias Neubert +1
The presence of a light b-squark (with mass about 4 GeV) and gluino (with mass about 15 GeV) might explain the observed excess in b-quark production at the Tevatron. Though provoca…
