Lattice techniques to investigate the strong problem: lessons from a toy model
David Albandea, Guilherme Catumba, Alberto Ramos
Recent studies have claimed that the strong problem does not occur in QCD, proposing a new order of limits in volume and topological sectors when studying observables on the l…
Progress in lattice simulations for two Higgs doublet models
Guilherme Catumba, Atsuki Hiraguchi, George W. -S Hou +5
The custodial Two-Higgs-Doublet-Model with SU(2) gauge fields is studied on the lattice. This model has the same global symmetry structure as the Standard Model but the additional…
The dependence of observables on action parameters
Guilherme Catumba, Alberto Ramos, Bryan Zaldivar
Many applications in Lattice field theory require to determine the Taylor series of observables with respect to action parameters. A primary example is the determination of electro…
Stochastic automatic differentiation for Monte Carlo processes
Guilherme Catumba, Alberto Ramos, Bryan Zaldivar
Monte Carlo methods represent a cornerstone of computer science. They allow to sample high dimensional distribution functions in an efficient way. In this paper we consider the ext…
