*Extracting Scattering Parameters using the Isospin Chemical Potential*

Michael Buchoff
Lawrence Livermore National Laboratory

Hadronic scattering mediated through the strong interaction has been an
area of great interest for both theory and experiment. Recently, lattice
QCD calculations of scattering processes from first principles have seen
remarkable progress, including multiple calculations of two-pion
scattering lengths that agree with experiment to within a few percent.
However, there exists a certain class of scattering processes, such as
pion-nucleon scattering, that contain annihilation diagrams, which are
prohibitively expensive to simulate on the lattice. In this talk, I will
present a method to extract certain parameters from this class of
scattering processes by employing an isospin chemical potential, which
can be simulated on the lattice as a result of its positive-definite
fermion determinant.
