Research in theoretical elementary particle physics will include a study of low energy flavor-violating decays of the K and B mesons in the context of supersymmetric grand unified theories, and a calculation of the production and decay of heavy right-handed neutrinos in the explosive reheating which follows inflation. The experimental observation and theoretical understanding of rare flavor- violating processes provide an important low energy window into very high energy physics, and such studies constitute a prominent component of the present endeavor in particle physics. The production of particles during the reheating process following the exponential expansion and cooling of the universe during inflation is decisive in determining the structure of our observable universe. The processing of heavy right-handed neutrinos subsequent to inflation may generate the presently observed asymmetry between matter and antimatter.

理论基本粒子物理学的研究将包括在超对称性大统一理论的背景下研究K和B介子的低能量风味侵入性衰变，以及在爆炸性重新加热的重型右手中微子的生产和衰减的计算。 对稀有风味的过程的实验观察和理论理解为非常高的能量物理学提供了重要的低能窗口，并且此类研究构成了当前粒子物理学目前努力的重要组成部分。 在通货膨胀期间指数膨胀和冷却后，在重新加热过程中的颗粒产生在确定可观察到的宇宙的结构方面是决定性的。 在通货膨胀之后的重右中微子的处理可能会产生目前观察到的物质和反物质之间的不对称性。
