Bananas of equal mass: any loop, any order in the dimensional regularisation parameter
Abstract We describe a systematic approach to cast the differential equation for the l-loop equal mass banana integral into an ε-factorised form. With the known boundary value at a specific point we obtain systematically the term of order j in the expansion in the dimensional regularisation paramete...
