Abstract
We study the fourth order normalized cumulant of height fluctuations governed by dimensional Kardar-Parisi-Zhang (KPZ) equation for a growing surface. Following a diagrammatic renormalization scheme, we evaluate the kurtosis from the connected diagrams leading to the value in the large-scale long-time limit.
