【 摘 要 】

Hadronic decays of the pi lepton provide a unique opportunity to probe the coupling of the weak current to the first and second generations of quarks with unprecedented precision. For decays with unity strangeness (in other words, there is an odd number of kaons in the final state), the CKM matrix element 'Vus' and the strange quark mass ms can be extracted with the spectral density function via Finite Energy Sum Rules.
