چکیده
A bstract We study the six-particle amplitude in planar $$ \mathcal{N} N = 4 super Yang-Mills theory double scaling (DS) limit, only nontrivial codimension-one boundary of its positive kinematic region. construct relevant function space, which is significantly constrained due to extended Steinmann relations, up weight 13 coproduct form, and 12 as an explicit polylogarithmic representation. Expanding latter collinear DS using Pentagon Operator Product Expansion, we compute non-divergent coefficient a certain component Next-to-Maximally-Helicity-Violating through eight loops. also specialize our results overlapping origin observing general pattern for leading divergences.

Double Scaling Limit of the Supervirasoro Constraints
⋆ Permanent address: Universität Bonn, Physikalisches Institut, Nussallee 12, W-5300 Bonn 1, Germany. We obtain the double scaling limit of a set of superloop equations recently proposed to describe the coupling of two-dimensional supergravity to minimal superconformal matter of type (2, 4m). The continuum loop equations are described in terms of a ĉ = 1 theory with a Z2-twisted scalar field an...
متن کاملScaling Limit and Critical Exponents for Two-Dimensional Bootstrap Percolation
Consider a cellular automaton with state space {0, 1}Z2 where the initial configuration ω0 is chosen according to a Bernoulli product measure, 1’s are stable, and 0’s become 1’s if they are surrounded by at least three neighboring 1’s. In this paper we show that the configuration ωn at time n converges exponentially fast to a final configuration ω̄, and that the limiting measure corresponding to...
متن کاملThe Supereigenvalue Model in the Double–Scaling Limit
The double–scaling limit of the supereigenvalue model is performed in the moment description. This description proves extremely useful for the identification of the multi-critical points in the space of bosonic and fermionic coupling constants. An iterative procedure for the calculation of higher–genus contributions to the free energy and to the multi–loop correlators in the double–scaling limi...
متن کاملN ) Vector Field Theories in the Double Scaling Limit
O(N) invariant vector models have been shown to possess non-trivial scaling large N limits, at least perturbatively within the loop expansion, a property they share with matrix models of 2D quantum gravity. In contrast with matrix models, however, vector models can be solved in arbitrary dimensions. We present here the analysis of field theory vector models in d dimensions and discuss the natur...
متن کاملUniversality of the double scaling limit in random matrix models
We study unitary random matrix ensembles in the critical case where the limiting mean eigenvalue density vanishes quadratically at an interior point of the support. We establish universality of the limits of the eigenvalue correlation kernel at such a critical point in a double scaling limit. The limiting kernels are constructed out of functions associated with the second Painlevé equation. Thi...
