PACS. 04.50+h - Gravity in more than four dimensions, Kaluza-Klein theory,
unified field theories; alternative theories of gravity.
PACS. 03.65Bz - Foundations, theory of measurement, miscellaneous theory (including Aharonov-Bohm effect, Berry's phase).
The geometric phase, connected to the Berry phase, for Dirac particles is calculated in the framework of theories of gravity with torsion. It turns out that torsion source may be interpreted a sort of curvature in the projective space of states.
