2-gnerated axial algebras of Monster type (2b, b)

Axial algebras of Monster type are a class of non-associative algebras that includes, besides associative algebras, other important examples such as the Jordan algebras and the Griess algebra. 2-generated primitive axial algebras of Monster type (a, b) naturally split into three cases: the case when a\not \in {2b,4b}, the case a=4b and a=4b. In this paper we give a complete classification all 2-generated primitive axial algebras of Monster type (2b,b)
