# SymEFT predictions for the asymptotic lattice spacing dependence of Wilson and GW quarks

#### SymEFT predictions for the asymptotic lattice spacing dependence of Wilson and GW quarks

- Event time: 2:00pm until 3:00pm
- Event date: 25th January 2023
- Speaker: Nikolai Husung (University of Southampton)
- Location: Higgs Centre Seminar Room, Room 4305, James Clerk Maxwell Building (JCMB) (James Clerk Maxwell Building (JCMB)) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

A major systematic uncertainty of predictions from lattice QCD arises due to the continuum extrapolation. Use of Symanzik Effective Field Theory allows to describe the asymptotic lattice spacing dependence of quantities obtained on the lattice. This puts continuum extrapolations and the corresponding error estimates on more solid grounds and may yield some insight on how to improve the lattice setup. I will discuss some results obtained for spectral quantities with Wilson or Ginsparg-Wilson quarks including some generalisations. Eventually I will give an outlook of what is currently being done and what remains to be done (at the very least).
