Theoretical Studies of Electroweak and Hadronic Interactions

理论基本粒子物理学的研究将包括在未来的对撞机中对可能的希格斯粒子信号的分析，在天体物理学感兴趣的情况下对光子和中微子之间相互作用的研究，以及旨在简化低能反应处理的“有效场论”的效用和有效性的调查。希格斯粒子与质量的起源有关，为了充分理解质量的起源和基本粒子理论的潜在对称性，必须确定它们的数量，以及它们的相对质量和电荷。光子和中微子只有在极端条件下才能明显地相互作用，比如在早期宇宙或致密天体中发现的条件。重要的是要确定这种相互作用是否会改变我们对宇宙学中残留的中微子或重物体释放能量的方式等事物的看法。由于有效场论为许多过程的低能量行为提供了方便的描述，因此有必要用在所有能量下都准确的精确理论来检验它们。

Research in theoretical elementary particle physics will include analyses of possible Higgs particle signals at future colliders, studies of the interactions between photons and neutrinos in situations of astrophysical interest, and investigations of the utility and validity of `effective field theories` intended for the simplified treatment of low-energy reactions. The Higgs particles are related to the genesis of mass, and their number, as well as their relative masses and charges, must be determined in order to fully understand the origin of mass and the underlying symmetry of elementary particle theory. Photons and neutrinos only interact appreciably under extreme conditions such as those found in the early universe or in compact astrophysical objects. It is important to determine if this interaction alters our view of such things as the relic neutrinos in cosmology or the way in which heavy objects loose energy. Since effective field theories provide a convenient description of the low energy behavior of many processes, it is essential to check them against exact theories which are accurate at all energies.
