The high-mass spectrum of lepton and photon pairs is sensitive to a broad array of new physics. Examples are searches for extra dimensions in different models in the dielectron, dimuon, and diphoton channels, and Z´ bosons with Standard-Model-like couplings to fermions as well as in a variety of GUT- inspired models. A direct search for electron compositeness is possible in the...

Randall-Sundrum scenarios offer a well-motivated alternative to supersymmetry as a solution to the hierarchy problem. In addition, bulk fermions allow for an interesting geometrical origin of the observed flavor hierarchies, as well as a natural suppression of neutral flavor changing effects. Recent progress has allowed to control potentially large contributions to the electroweak precision...

Many theories beyond the Standard Model predict new particles that can mediate sub-gravitational strength forces at short distances. Recent advances in atom interferometry will allow a new round of experiments searching for sub- gravitational strength forces in the 1 micron to 100 meter length scales. I will describe the experiments and prospects for future improvements.

In the late nineties several authors suggested that the extra dimensions predicted by string theory might lead to observable effects at high energy colliders. The ATLAS experiment which will start taking data at the LHC in 2007 will be an excellent place to search for such effects. A large set of models within the ADD or the Randall Sundrum geometries has been studied in ATLAS. These...

386. Gravitational Fixed Points and Virtual-Graviton Signals at LHC

LHC searches for extra-dimensional graviton signals suffer from a general problem: in addition to the fundamental Planck scale we have to introduce a cutoff (roughly of the order of the Planck scale) to compute collider effects. A slight misalignment between the Planck scale and this cutoff has huge effects for example on virtual-graviton observables. Starting completely generally...

Twelve years after the discovery of the Top Quark at Fermilab's Tevatron, we are now finally beginning to shed light on this peculiarly massive quark. With the large datasets from CDF, we are able to probe the Standard Model top quark, and to search for signals of physics beyond the Standard Model. We present results of measurements of top quark properties, such as the charge of the...
