Lattice evidence that scalar glueballs are small
Ryan Abbott, Daniel C. Hackett, Dimitra A. Pefkou +2
This work reports the first calculation of the gravitational form factors (GFFs) of the scalar glueball, performed via lattice field theory in Yang-Mills theory at a single lattice…

Filtered Rayleigh-Ritz is all you need
Ryan Abbott, Daniel C. Hackett, George T. Fleming +2
Recent work has shown that the (block) Lanczos algorithm can be used to extract approximate energy spectra and matrix elements from (matrices of) correlation functions in quantum f…

Gravitational form factors of glueballs in Yang-Mills theory
Ryan Abbott, Daniel C. Hackett, Dimitra A. Pefkou +2
This work presents preliminary results of the first determination of the energy-momentum tensor form factors of the scalar glueball, referred to as gravitational form factors (GFFs…
