David Atwood Iowa State It has long been considered futile to attempt to observe quantum gravitational phenomena with conventional particle colliders since gravitational effects are expected to be very weak at energy scales below the Planck mass. In recent years, the idea has been put forward that some compact dimensions (Kaluza-Klein) may in fact be very large which would lead to a great enhancement of gravity at short distances. In models of this sort, gravitational effects may be come evident at TeV energy scales and therefore searched for at proposed colliders such as LHC, NLC and future runs of the Tevatron. In this talk I will discuss the general features of models with large extra dimensions which lead to low energy gravitational phenomena and discuss some experiments which could potentially observe such effects.
