Strings, gravity and particle physics

Summary

This contribution, aimed mostly at experimental particle physicists, reviews some of the main ideas and results of string theory in a non-technical language. It originates from the talks presented by the authors at the electroweak session of the 2002 Moriond Meeting, here merged in an attempt to provide a more complete and concise view of the subject and updated to include a brief account of some recent developments.

Acknowledgments

This text originated as a write up of talks given by the authors at the 2002 Moriond Electro-Weak meeting. We are grateful to the organizers for their encouragement to merge our contributions in this short review aimed mostly at experimental particle physicists. The work of the first author was supported in part by INFN and by the European Commission FP6 RTN programme HPRN-CT-2004-512194 and by the INTAScontract 03-51-6346. The work of the second author was supported in part by the European Commission FP6 RTN programme MRTN-CT-2004-005104, in part by the Belgian Federal Science Policy Office through the Interuniversity Attraction Pole P6/11, and in part by the “FWO-Vlaanderen” through project G.0428.06. We are grateful to C. Angelantonj, J. Lemonne, J. Troost, G. Stefanucci and F. Zwirner for useful suggestions and comments on the manuscript. when this paper first appeared the first author was at dipartimento di fisica, universita di roma “tor vergata”. finally, we are grateful to L. Cifarelli for her interest in this review and for her kind invitation to publish it in the present form in rivista del nuovo cimento.
