关于行走的彩色、全息照相术和规范/重力对偶的讲座

Lectures on walking technicolor, holography and gauge/gravity dualities

Maurizio Piai

摘要:

动力学电弱对称破缺是一种吸引人的、强耦合的替代方案,它取代了基于基本标量场的弱耦合模型,从而产生真空期望值。在本系列讲座的前两节中,我总结了基于低能量现象学的论点,支持将彩色行走作为这一想法的现实实现。这教学介绍步行技术色彩,更普遍的物理学的扩展的标准模型,广泛使用有效场论的论点,对称性和计数规则。强耦合的基本相互作用的性质,和特殊的准共形行为的理论,需要使用非微扰的方法,以解决这个框架内的许多基本问题。最近发展的规范/重力对偶提供了一套理想的非微扰仪器。剩下的两个部分用两个技术例子说明了这些技术的潜力,一个是在五维全息的自下而上的唯象方法中,另一个是在来自十维IIB型超引力的更系统的自上而下的结构中。

英文摘要:

Dynamical electro-weak symmetry breaking is an appealing, strongly-coupled alternative to the weakly-coupled models based on an elementary scalar field developing a vacuum expectation value. In the first two sections of this set of lectures, I summarize the arguments, based on low-energy phenomenology, supporting walking technicolor as a realistic realization of this idea. This pedagogical introduction to walking technicolor, and more generally to the physics of extensions of the standard model, makes extensive use of effective field theory arguments, symmetries and counting rules. The strongly-coupled nature of the underlying interactions, and the peculiar quasi-conformal behavior of the theory, require to use non-perturbative methods in order to address many fundamental questions within this framework. The recent development of gauge/gravity dualities provides an ideal set of such non-perturbative instruments. The remaining two sections illustrate the potential of these techniques with two technical examples, one within the bottom-up phenomenological approach to holography in five-dimensions, the other within a more systematic top-down construction derived from ten-dimensional type-IIB supergravity.
