DESCRIPTION:Speakers: Prof. MELIKHOV\, Dmitri (HEPHY & SINP)\nWe study the
  decay constants of D\, Ds\, B\, Bs mesons with Borel QCD sum rules\, maki
 ng use of the recent modifications related to the Borel-parameter-dependen
 t effective continuum threshold. For the fixed values of the QCD parameter
 s\, our modifications are shown to lead to a visible shift of the extracte
 d value of the decay constant compared to the standard analysis based on a
  Borel-parameter-independent threshold. We argue that our modifications al
 low one to probe the systematic errors of the extracted decay constants. W
 e provide rather accurate results for fD and fDs. We demonstrate that an a
 ccurate extraction of fB and fBs is only possible if a very precise value 
 of m_b(m_b) is known.\n\nhttp://indico.cern.ch/contributionDisplay.py?cont
