Abstract Starting from a factorization theorem in effective field theory. we derive a parton-shower equation for the resummation of non-global logarithms. We have implemented this shower and interfaced it with a tree-level event generator to obtain an automated framework to resum the leading logarithm of non-global observables in the large-N c limit. Using this setup. https://parisnaturalfoodes.shop/product-category/f-f-niacin/
