Glueball scattering cross section in lattice Yang-Mills theory

N Yamanaka, H Iida, A Nakamura, M Wakayama - Physical Review D, 2020 - APS
We calculate the scattering cross section between two 0++ glueballs in SU (2) Yang-Mills
theory on a lattice at β= 2.1, 2.2, 2.3, 2.4, and 2.5 using the indirect (HAL QCD) method. We …
