The gluino-glue particle and finite size effects in supersymmetric Yang-Mills theory

Understand

The spectrum of particles in supersymmetric Yang-Mills theory is expected to contain a spin 1/2 bound state of gluons and gluinos, the gluino-glue particle.

• We study the mass of this particle in softly broken supersymmetric Yang-Mills theory on a lattice by means of numerical simulations.
• The main focus is the estimation of finite size effects.
• We extrapolate the mass first to the infinite volume and then to the limit of a vanishing gluino mass.
