DESCRIPTION:Deep-inelastic scattering of charged or neutral leptons off pr
 oton and deuteron targets allows to measure the leading twist parton densi
 ties of the nucleon\, the QCD-scale Lambda_QCD\, and the strong coupling c
 onstant to high precision. For unpolarized DIS via single photon exchange\
 , the cross section can be expressed in terms of two inclusive structure f
 unctions F2(x\,Q^2)\, FL(x\,Q^2). Of particular interest are the c(cbar)-c
 ontributions to these structure functions\, which\, especially in the regi
 on of smaller values of Bjorken-x\, provide contributions of up to 20-40%.
  In the limit of large momentum transfer\, these contributions are very we
 ll described by asymptotic expressions\, where the mass dependence\, up to
  polynomial terms in m^2/Q^2\, is described by massive Operator Matrix Ele
 ments (OMEs). I will report on the calculation of these OMEs up to 3-loop 
 order for fixed even moments of the Mellin variable N and the calculation 
 of the OMEs which are required to define heavy quark parton densities in t
 he variable flavor number scheme.\n\nhttps://indico.ific.uv.es/event/1741/
