Research in the Quantum Field Theory of Elementary Particles

[9511632]温伯格弦理论是一种尝试，它试图超越将基本粒子描述为类点粒子的量子力学描述，而将它们表述为微观类弦物体的激发。这些激发态不仅包括夸克、胶子、轻子等。还有引力子，引力的量子激发，这样我们就有了一个真正统一的所有相互作用的理论。这项研究的目的之一是更好、更深入地理解时空和量子引力理论。第二个目标是探索这种理论与标准模型所描述的传统粒子物理学的联系，以及它对天体物理学和宇宙学测量的影响。* * *

9511632 Weinberg String theory is an attempt to move beyond the quantum mechanical description of elementary particles as point like particles to a formulation of them as excitations of a microscopic string-like objects. These excitations would include not only quarks, gluons, leptons ,etc., but also the graviton, the quantum excitation of gravity so that one would have a truly unified theory of all interactions. One aim of this research is a better and deeper understanding of space-time and a quantum theory of gravity. A second aim is to explore the links of such a theory to conventional particle physics as described by the standard model and its implications for astrophysical and cosmological measurements. ***
