| | 25 | In the upper inset, we clearly see the finite width effects for large values of $\lambda$. These become progressively smaller and indiscernible below $10^{-3}$. When dividing this difference by lambda, as done in the lower inset, we only see a mild deviation with respect to a constant. Changing the LO width used for the test by as little as 0.1 % already yields a larger $\kappa^{\text{NLO}}_0$ than the residual one stemming from numerical inaccuracies. Changing the analytical continuation of the logarithms of the UV wavefunctions counterterms to make them incorrect would yield an asymptot in the $\Delta^{NLO}/\lambda$ plot of the order of thousands, clearly assessing the sensitivity of the test towards any incorrect CMS implementation at NLO. |
