First steps towards gauge-independent vortex identification through machine learning
Wyatt A. Smith, César Fernández-RamÃrez, Jeff Greensite +1
As a first step towards machine identification of confining objects in thermalized lattice gauge configurations, we present our 2dVoId model for center vortex identification on pur…
Varieties of electrically charged physical states in SU(2)U(1) lattice gauge Higgs theory
Jeff Greensite
We consider a quenched SU(2)U(1) gauge Higgs theory on the lattice, coupled to a static vector-like fermion which, in this case, is in the same gauge group representation a…
Excitations of gauge bosons, and other aspects of gauge Higgs theories
Jeff Greensite
I review the qualitative physical distinction between the Higgs and confinement phases of a gauge Higgs theory, and the non-local order parameter introduced by Matsuyama and myself…
Does the Z boson have a lighter cousin?
Jeff Greensite
In the quenched electroweak theory on the lattice I construct a set of physical states which overlap the physical photon and Z boson states. This is done by employing eigenstates o…
