The static energy renormalon from high order perturbative expansions

Friday March 9, 14:30hs -  Seminar room

Speaker: Clemens Bauer (University of Regensburg, Germany)

Abstract:

Using Numerical Stochastic Perturbation Theory (NSPT), we calculate the static self-energy of SU(3) gauge theory up to order $\alpha^{20}$ .

Simulations on a large set of different lattice volumes allow for a careful treatment of finite size effects. The resulting infinite volume perturbative series of the static self-energy is in remarkable agreement with the predicted asymptotic behaviour of high order expansions, namely with a factorial growth of perturbative coefficients known as renormalon.
