PVA

PVA[r,m0]
is the Passarino-Veltman coefficient function .

Details and OptionsDetails and Options

  • PVA[r,m0] is the symbolic form of the coefficient function multiplying the symmetrized tensor generated by LoopIntegrate.
  • PVA[r,m0] implicitly depends on the number of spacetime dimensions .
  • PVA[0,m0] represents the scalar function with full dependence on .
  • PVA does not directly evaluate. LoopRefine substitutes PVA with its explicit expression.
  • PVA[r,m0,Weights{w0}] represents the weighted coefficient function .
  • PVA[r,m0,Dimensionsn] represents the coefficient function in spacetime dimensions.
  • The following are equal to PVA[r,m0] in other packages:
