Title: Multijet merging in a variable flavor number scheme

Abstract

We introduce a novel technique for the combination of multijet merged simulations in the five-flavor scheme with calculations for the production of b-quark associated final states in the four-flavor scheme. We show the equivalence of our algorithm to the FONLL approach at the fixed-order and logarithmic accuracy inherent to the matrix-element and parton-shower simulation employed in the multijet merging. As a first application, we discuss $$Zb\bar{b}$$ production at the Large Hadron Collider.
