Large Dimensions and String Physics at the TeV
Ignatios Antoniadis
E. Polytechnique
If the fundamental type I string scale is at the TeV, the apparent
weakness of gravity is due to the existence of large extra dimensions,
in the range of a millimeter to a fermi, transverse to the D-brane
where the Standard Model particles are localized. This scenario
offers a new framework for solving the gauge hierarchy and unifying
gauge and gravitational interactions. Furthermore, it has
spectacular consequences for physics at future colliders, such as the
production of Kaluza-Klein and string excitations, or graviton
emission into the extra dimensions. It also accomodates naturally TeV
dimensions that may be responsible for supersymmetry breaking,
leading to a superparticle spectrum very different than in usual
gravity or gauge mediation. Finally, it predicts a drastic change of
gravitational forces at sub-millimeter distances that could be tested
experimentally.
The almuerzo-seminario is
intended to be an informal seminar and an open forum for discussion.
You are wellcome to bring your own
