  We study the relativistic quantum of scalar particles in the cosmic string
space-time with a screw dislocation (torsion) subject to a uniform magnetic
field including the magnetic quantum flux in the presence of potential. We
solve the Klein-Gordon equation with a Cornell-type scalar potential in the
considered framework and obtain the energy eigenvalues and eigenfunctions and
analyze a relativistic analogue of the Aharonov-Bohm effect for bound states
