Searching for symmetric mass generation with staggered fermions in four dimensions
Nouman Butt, Simon Catterall, Gwen Hartshaw +1
We conduct numerical simulations to map out the phase diagram and critical behavior of a lattice Higgs model composed of two massless staggered fermion fields forming a doublet und…
Gradient Flow Renormalization Schemes for Composite Fermion Operators
Matthew Black, Anna Hasenfratz, Oliver Witzel
We introduce gradient flow (GF) normalization prescriptions for fermionic composite operators in which the flowed fermion wavefunction renormalization factor is fixed nonperturbati…
A Guide to Symmetric Mass Generation in Lattice-QCD
Anna Hasenfratz, Cenke Xu
Symmetric mass generation (SMG) has attracted growing interest in both condensed matter theory and lattice-QCD communities. Here we formulate general criteria for SMG and examine t…
Renormalized quark masses using gradient flow
Matthew Black, Robert V. Harlander, Anna Hasenfratz +2
We propose a new and simple method for determining the renormalized quark masses from lattice simulations. Renormalized quark masses are an important input to many phenomenological…
Towards determination of the strong coupling from four-flavor lattice QCD using the continuous -function method
Yash Mandlecha, Alexei Bazavov, Akhil Chauhan +10
The precise value of the strong coupling at the -boson mass is essential for high-energy phenomenology and precision tests of quantum chromodynamics (QCD).…
Symmetric Mass Generation
Anna Hasenfratz, Oliver Witzel
In recent years tantalizing signs for a novel phase have been reported that is chirally symmetric but nevertheless exhibits massive bound states. The necessary condition for such a…
