Lattice seminarNon-perturbative decoupling of massive fermions
Dr. Tobias Rindlisbacher (Universität Bern, AEC)
SU(2) gauge theory with Nf=24 massless fermions has a trivial infrared fixed point and is therefore non-interacting at long distances. If the fermions are massive, the behavior changes dramatically as the fermions will now decouple at energy scales below the fermion mass and the infrared behavior becomes that of confining SU(2) pure gauge theory. In this talk I will discuss our recent efforts to demonstrate the latter behavior non-perturbatively with lattice Monte Carlo simulations and the gradient flow running coupling.
