-==introduction==
-* S-matrix describes the infrared data of the model
-* it is important to check that the UV limit of the model coincides with the conformal field theory that was originally perturbed
-* TBA is a method which provides such a check
-==perturbed action==
-* $\mathcal{A}_{SLYM}=\mathcal{A}_{M_{2,5}}+i \lambda \int d^2x \varphi(x)$
-* $M=(2.642944662\cdots) \lambda^{5/12}$ where $M$ is the single particle mass
-* http://www.wolframalpha.com/input/?i=2.642944662
-* spin of conserved charges : 1,5,7,11,13,17,19, ...
-==S-matrix==
-* 1 particle
-* S-matrix
-$$
-S_{11}(\theta)=\tanh \left(\frac{1}{2} \left(\theta -\frac{2 i \pi }{3}\right)\right) \coth \left(\frac{1}{2} \left(\theta +\frac{2 i \pi }{3}\right)\right)
-$$
-* 커널
-$$
-\phi_{11}(\theta)=-i\frac{d}{d\theta}\log S_{11}(\theta)=\sqrt{3} \left(\frac{1}{2 \cosh (\theta )+1}+\frac{1}{2 \cosh (\theta )-1}\right)
-$$
-==TBA analysis==
-*
-$$
-N=\frac{1}{2\pi}\int_{-\infty}^{\infty}\phi_{11}(\theta)=1
