SO(10) Grand Unification,i [1]. Unlike SU(5), SO(10) is a group of rank 5 with the extra diagonal generator of SO(10) being . as in the left-right symmetric groups. The advantages of SO(10) over SU(5) grand unification are that:

微枝末节

Beyond , = 1 Supergravity,c unification that described all four forces of nature, weak electromagnetic, and strong as well as gravitational, within one theoretical framework. A theorist’s dream is, however, more ambitious and rightly so, since, even the very elegant . = 1 supergravity leaves many questions unanswered: a partial list includes:

使混合

Important Basic Concepts in Particle Physics,Forces observed in nature can be classified into four categories according to their observed strength at low energies: strong, electromagnetic, weak, and gravitational. Their strengths, when characterized by dimensionless parameters, are roughly of the following orders of magnitude:

Champion

Spontaneous Symmetry Breaking, Nambu-Goldstone Bosons, and the Higgs Mechanism,A Lagrangian for a physical system may be invariant under a given set of symmetry [1] transformations; but how the symmetry is realized in nature depends on the properties of the ground state. In field theories the ground state is the vacuum state. We will, therefore, have to know how the vacuum state responds to symmetry transformations.

Technicolor and Compositeness,In the previous chapters we have emphasized that while the success of the SU(2). × U(1). × SU(3). model has indicated that the unified gauge theories are perhaps the right theoretical framework for the study of quark-lepton interactions, it still leaves a lot of questions unanswered. Some of the outstanding questions are:
