  • High Energy Theory seminar: "Shift Symmetries in (A)dS"

    David Rittenhouse Laboratory, 2N36

    Kurt Hinterbichler, Case Western Reserve University

    I will discuss the generalizations of shift symmetries, galileon symmetries, and extended galileon symmetries to (A)dS space and to higher spin.   Unlike flat space, these symmetries are present only for particles with particular masses, and are related to partially massless symmetries.  For the case of scalars, I will discuss non-linear extensions of the symmetries and invariant interactions. This leads to a unique ghost-free theory in (A)dS space that is an (A)dS extension of the special Galileon.
