We show that the system of one-sided reflected Brownian motions considered in
WFS17 has integrable transition probabilities, expressed in terms of Hermite
polynomials and hitting times of exponential random walks, and converges in the
1:2:3 scaling limit to the KPZ fixed point, the scaling invariant Markov
process defined in MQR17 and believed to govern the long time large scale
fluctuations for all models in the KPZ universality class. The reflected
Brownian motion system is in variational duality to Brownian last passage
percolation, shown recently in DOV18 to converge to the Airy sheet (or
directed landscape), defined there as a strong limit of a functional of the
Airy line ensemble. This establishes the variational formula for the KPZ fixed
point in terms of the Airy sheet.
