2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/179397We continue our investigation of the phenomenological implications of the "deformed" commutation relations [x_i,p_j]=i hbar[(1 + beta p^2) delta_{ij} + beta' p_i p_j]. These commutation relations are motivated by the fact that they lead to the minimal length uncertainty relation which appears in perturbative string theory. In this paper, we consider the effects of the deformation on the classical orbits of particles in a central force potential. Comparison with observation places severe constraints on the value of the minimum length.20 pages REVTEX4, 4 color eps figures, typos correctedHigh Energy Physics - TheoryAstrophysicsHigh Energy Physics - Phenomenologytext
