Title: Heavy-light Diquark Mass Splitting from QCD Sum-Rules and Diagrammatic Renormalization Methods QCD Abstract: Laplace sum-rules are an important tool to extract information about bound states of quarks from perturbative QCD with non-perturbative effects of QCD condensates. Applying the QCD Laplace sum-rules to strange and non-strange heavy-light diquarks, I compare their masses. Diquark correlation functions are renormalized using the diagrammatic renormalization method. It is found that the strange quark condensate parameter $\kappa = \langle \bar{s}s\rangle/\langle\bar{n}n\rangle$ plays an important role in determining the heavy-strange $[Qs]$ and heavy-non-strange $[Qn]$ diquark mass splitting.
