标题： Electroweak and Flavor Dynamics at Hadron Colliders

摘要： 我们为1996年新方向高能物理Snowmass研讨会整理了电弱和 flavour 动力学在 $\pbarp$ 和 $pp$ 对撞机上的主要特征。我们假定的自发对称性破缺框架是 Technicolor（技术 colour），具有行走耦合 $\atc$ 和扩展的技术 colour。讨论的反应主要发生在子过程能量 $\rshat \simle 1\,\tev$ 上。 这些反应包括颜色单态和技术 rho八重态的产生及其衰变到技术 pion 对、纵向弱玻色子或喷注。技术 pion 则主要衰变为重费米子。 这些特征中的许多也预计会在 topcolour 辅助的技术 colour 中出现。此外还讨论了几个特定于此新场景的粒子。与夸克和轻子亚结构相关的 flavour 动力学的额外特征可能表现在高 $E_T$ 和不变质量的二喷注和二轻子的过剩产生率上。这些过程的一个重要特征是它们表现出相当集中的角度和快速度分布。 显示英文摘要

摘要： We catalog the principal signatures of electroweak and flavor dynamics at $\pbarp$ and $pp$ colliders for use at the 1996 Snowmass Workshop on New Directions in High Energy Physics. The framework for dynamical symmetry breaking we assume is technicolor, with a walking coupling $\atc$, and extended technicolor. The reactions discussed occur mainly at subprocess energies $\rshat \simle 1\,\tev$. They include production of color-singlet and octet technirhos and their decay into pairs of technipions, longitudinal weak bosons, or jets. Technipions, in turn, decay predominantly into heavy fermions. Many of these signatures are also expected to occur in topcolor-assisted technicolor. Several particles specific to this new scenario are discussed. Additional signatures of flavor dynamics, associated with quark and lepton substructure, may be sought in excess production rates for high $E_T$ and invariant mass dijets and dileptons. An important feature of these processes is that they exhibit fairly central angular and rapidity distributions.
