Extending the kinetic mass to higher orders in 1/mQ

A bstract Currently, the kinetic mass is defined in terms of the pole mass and operators at order $$1/{m}_{Q}^{2}$$ , which are known to N 3 LO accuracy in α s . At the same time, the Heavy Quark Expansion (HQE) for inclusive semileptonic decays is known up to and including terms...
