摘要: Massless flows from the coset model su(2)k+1⊗su(2)k/su(2)2k+1su(2)k+1⊗su(2)k/su(2)2k+1 to minimal Mk+2Mk+2 are studied viewpoint of form factors. These include in particular flow tricritical Ising model. By analogy with magnetization operator TIM→IMTIM→IM, we construct all factors an that Φ1,2Φ1,2 IR. We make a numerical estimation difference conformal weights between UV and IR thanks Δ -sum rule; results consistent weight Φ2,2Φ2,2 UV. energy TIM → IM, Φ2,1Φ2,1. propose identify σ1Φ1,2σ1Φ1,2.
