Abstract:

We calculate the lowest-order corrections to the static potential for both Yang–Mills theory and gluodynamics in curved space–time, in the presence of a quantum gravity induced minimal length. Our analysis is carried out within stationary perturbation theory. As a consequence, the potential energy is the sum of a Yukawa-like potential and a linear potential for gluodynamics in curved space–time, leading to the confinement of static charges. Interestingly, we find that the coefficient of the linear term (‘string tension’) is ultraviolet finite. We highlight the role played by the new quantum of length in our analysis.
