How perturbative are heavy sea quarks?
Andreas Athenodorou, Jacob Finkenrath, Francesco Knechtli +4
Effects of heavy sea quarks on the low energy physics are described by an effective theory where the expansion parameter is the inverse quark mass, 1/. At leading order in 1/…
Power corrections from decoupling of the charm quark
Francesco Knechtli, Tomasz Korzec, Björn Leder +1
Decoupling of heavy quarks at low energies can be described by means of an effective theory as shown by S. Weinberg in Ref. [1]. We study the decoupling of the charm quark by latti…
Green-Schwarz superstring on the lattice
Lorenzo Bianchi, Marco S. Bianchi, Valentina Forini +2
We consider possible discretizations for a gauge-fixed Green-Schwarz action of Type IIB superstring. We use them for measuring the action, from which we extract the cusp anomalous…
Lattice and string worldsheet in AdS/CFT: a numerical study
Valentina Forini, Lorenzo Bianchi, Marco S. Bianchi +2
We consider a possible discretization for the gauge-fixed Green-Schwarz (two-dimensional) sigma-model action for the Type IIB superstring and use it for measuring the cusp anomalou…
Perturbative versus non-perturbative decoupling of heavy quarks
Francesco Knechtli, Mattia Bruno, Jacob Finkenrath +2
We simulate a theory with heavy quarks of mass . At energies much smaller than the heavy quarks decouple and the theory can be described by an effective theory which…
Tuning of the strange quark mass with optimal reweighting
Björn Leder, Jacob Finkenrath
Quark mass reweighting can be used to tune the mass of dynamical quarks. The basic idea is to use gauge field ensembles generated at some bare mass parameters to evaluate observabl…
