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.

预计未来5-10年对粒子物理学来说将是非常令人兴奋的。粒子相互作用的唯一实验证实的模型，标准模型，包含一些基本的理论不一致。物理学家已经构建了几个替代模型，但这些模型还没有得到测试的机会。欧洲核子研究中心（CERN）的大型强子对撞机（LHC）和国际直线对撞机（ILC）可能会改变这一切，预计LHC将于2007年开始收集数据。然而，如果产生的数据与标准模型预测的数据不一致，那么一个重要的问题就是：标准模型之外的哪一种情景与实验信号一致。我打算研究这个问题，主要集中在我们在Concordia开发的模型上，该模型将超对称性（费米子-玻色子对称性）和左右对称性（镜像或宇称）纳入标准模型。我计划集中在这个模型最有希望的迹象，并从其他模型中获得的信号解开这些。因此，与此同时，我也将研究其他可能的模式。我的一些研究将涉及将LHC获得的数据与ILC的信号进行比较，在ILC中，背景信号不那么复杂，并且这个特定的模型可以提供更确定的事件，其中一些将是相当壮观的。这个项目代表了我对这个特定模型及其在对撞机上的区别标志的兴趣的延续。我建议以一种系统的方式开始，并清楚地描绘出模型预测的一致性，然后继续寻找可能的偏差，从更知名的，更广泛的探索，模型。我和我在Concordia的团队（研究生和一名博士后）一起工作，但我也和以色列、欧洲和美国的团队合作。
