src/interface/ga0 [ Functions ]

[ Top ] [ Functions ]

NAME

  Function ga0

USAGE

  complex = ga0(m1,mu2,eps_flag)

DESCRIPTION

  This function corresponds to the scalar a0 function.
  There are two arguments more which are the renormalisation
  scale squared and a flag which selects the coefficient of
  the Laurent series in epsilon

INPUTS

  * m1 -- a real (type ki), mass^2 of propagator 1
  * mu2 -- a real (type ki), renormalisation scale squared
  * eps_flag -- an integer, a flag to select the coefficient in front the power of epsilon

SIDE EFFECTS

  No side effect

RETURN VALUE

  It returns a complex (type ki) corresponding
  to the real part, imaginary part of the coefficient in front 1/epsilon^2 (eps_flag=-2),
  the real part, imaginary part of the 1/epsilon term (eps_flag=-1) and the real part,
  imaginary part of the constant term (eps_flag=0).

USES

  * precision (src/module/precision_golem.f90)
  * matrice_s, only: set_ref, s_mat, allocation_s, deallocation_s, init_invs (src/kinematic/matrice_s.f90)
  * form_factor_type, only: form_factor (src/module/form_factor_type.f90)
  * form_factor_1p (src/form_factor/form_factor_1p.f90)
  * form_factor_higher_ranks (src/form_factor/form_factor_higher_ranks.f90)
  * constante, only : b_null (src/module/constante.f90)
  * sortie_erreur, only : tab_erreur_par,catch_exception (src/module/sortie_erreur.f90)
