论文摘要
我们研究$ \ text {t} \ edropline {\ text {t}} $使用正式主义的手性玻色子的变形，因为参议员是任意数量的左 - 右手玻色子而引起的，我们发现$ \ text {t} \ text {t} \ edelline {\ text {\ text {\ text {\ text {\ text {森形式主义中的非本地行动。我们确定，在无限$ \ text {t} \ overline {\ text {t}} $耦合的极限上，变形理论的运动方程式表现出手性解耦。然后，我们进行讨论，讨论$ \ text {t} \ edromline {\ text {t}} $ deformed手性费米子，并指出$ \ text {t} \ text {t} \ overline {\ text {\ text {t}} $ defermion conconconcoceed conconcondece的压力张紧。我们通过指出该动作中的变形项本质上是纯粹的，并且与绿色 - 史克瓦尔兹形式主义中的费米子·祖米诺术语紧密相似，从而解释了压力张量的这种行为。反过来，这种观察也解释了文献中的一个难题，即。为什么$ \ text {t} \叠加{\ text {t}} $在线性顺序上截断了多个免费费米子的变形。最后，我们讨论了$ \ text {t} \ overline {\ text {t}} $变形和持续化之间的相互作用的可能性。
We study $ \text{T}\overline{\text{T}} $ deformations of chiral bosons using the formalism due to Sen. For arbitrary numbers of left- and right-chiral bosons, we find that the $ \text{T}\overline{\text{T}} $-deformed Lagrangian can be computed in closed form, giving rise to a novel non-local action in Sen's formalism. We establish that at the limit of infinite $ \text{T}\overline{\text{T}} $ coupling, the equations of motion of deformed theory exhibits chiral decoupling. We then turn to a discussion of $ \text{T}\overline{\text{T}} $-deformed chiral fermions, and point out that the stress tensor of the $ \text{T}\overline{\text{T}} $-deformed free fermion coincides with the undeformed seed theory. We explain this behaviour of the stress tensor by noting that the deformation term in the action is purely topological in nature and closely resembles the fermionic Wess-Zumino term in the Green-Schwarz formalism. In turn, this observation also explains a puzzle in the literature, viz. why the $ \text{T}\overline{\text{T}} $ deformation of multiple free fermions truncate at linear order. We conclude by discussing the possibility of an interplay between $ \text{T}\overline{\text{T}} $ deformations and bosonisation.
