摘　　要:

After making a brief introduction to the standard model, I will talk about recent advances in the standard model effective field theory. Regarding the standard model as an effective field theory, the low energy effects from high-scale physics are incorporated into a tower of higher dimensional operators. I first review the literature before our work, and then focus on three aspects: (1) The complete and independent set of dimension-seven operators and renormalization of a subset of them; (2) A power counting rule for renormalization of operators with the same dimension; (3) The complete and independent sets of dimension-six and -seven operators when light sterile neutrinos are introduced into the standard model. Some phenomenology will also be briefly discussed.
