30m

Tsung-Dao Lee Institute/S5F-S500 - Lecture Hall (Tsung-Dao Lee Institute)

Plenary Talk Session I (Day 2)

Speaker

Prof. Kiwoon Choi

Description

I discuss characteristic features of extra-dimensional axions arising from higher-dimensional gauge fields. Particular attention will be paid to the axion quality needed to solve the strong CP problem and to distinctive features of their low-energy couplings compared with conventional four-dimensional field-theoretic axions.
