DESCRIPTION:Speakers: GOMEZ-ROCHA\, Maria (University of Granada)\nWe stud
 y the influence of quark-pair contributions in weak transition form factor
 s of heavy-light mesons. Form factors are first calculated for space-like 
 momentum transfers in a frame where such contributions are supposed to be 
 suppressed. Analytical continuation to time-like region and comparison wit
 h the direct decay calculation provides an estimate of the role quark-pair
  contributions may play. We use the point form of relativistic quantum mec
 hanics\, suitable to heavy-light systems.\n\nhttps://indico.nucleares.unam
