Testing beyond MSSM scenarios at the LHC and ILC

The next 5-10 years are expected to be very exciting for particle physics. The only experimentally confirmed model for particle interactions, the Standard Model, contains some fundamental theoretical inconsistencies. Physicists have constructed several alternative models, but these have not yet had the chance of being tested. The Large Hadron Collider (LHC) at CERN and the International Linear Collider (ILC) are likely to change all that, with the LHC expected to start taking data in 2007. However, if the data produced turns out to be inconsistent with that predicted by the Standard Model, an important question will be: which one of the scenarios beyond the Standard Model is the one consistent with the experimental signals. I propose to investigate this question, focusing mostly on a model that we developed at Concordia, which incorporates supersymmetry (a fermion-boson symmetry) and left-right (mirror, or parity) symmetry into the Standard Model. I plan to concentrate on the most promising signs for this model, and disentangle these from signals obtained in other models. Thus, at the same time, I will be looking at other possible models as well. Some of my studies will involve comparing the data obtained at the LHC with signals at the ILC, where the background signals are less complicated, and where this particular model could provide more definite events, some of which would be rather spectacular. This project represents a continuation of my interest in this specific model and its distinguishing signs at colliders. I propose to start in a systematic way and draw a clear picture of what the model predicts consistently, then move on to search for possible deviations from the better known, and more widely explored, models. I work with my group at Concordia (graduate students and one postdoctoral fellow), but I also collaborate with groups in Israel, Europe and the US.
