Large N Analysis of $T\bar{T}$-deformation and Unavoidable Negative-norm States

Junichi Haruna, Takaaki Ishii, Hikaru Kawai +2

We study non-perturbative quantum aspects of $T\bar{T}$-deformation of a free $O(N)$ vector model by employing the large $N$ limit. It is shown that bound states of the original fi…
