Semi-analytical Solution of the Φ Theory on an F4 Lattice

  • Markus Klomfass
  • Published 1993


Investigating the cutoff dependence of the Higgs mass triviality bound, the φ theory is formulated on an F4 lattice which preserves Lorentz invariance to a higher degree than the commonly used hypercubic lattice. I solve this model non-perturbatively by evaluating the high temperature expansion through 13th order following the approach of Lüscher and Weisz… (More)
