NAME

  Module form_factor_1p

USAGE

  use form_factor_1p

DESCRIPTION

  This module contains the form factor for tadpoles.

OUTPUT

  It exports the functions:
  * a10 -- a function to compute A^{1,0}

USES

  * precision (src/module/precision_golem.f90)
  * generic_function_1p (src/integrals/one_point/generic_function_1p.f90)
  * matrice_s (src/kinematic/matrice_s.f90)
  * array (src/module/array.f90)
  * form_factor_type (src/module/form_factor_type.f90)
  * constante (src/module/constante.f90)

src/form_factor/form_factor_1p/a10_b [ Functions ]

[ Top ] [ Functions ]

NAME

  Function a10_b

USAGE

  type(form_factor) = a10_b(b_pin)

DESCRIPTION

 This function defines the form factor A^{1,0}.

INPUTS

 * b_pin -- an integer whose bits represent an array of integers of rank 1 corresponding 
            to the label of the propagators pinched (removed from the original set
            which is in the global variable b_ref)

SIDE EFFECTS

  No side effect, it uses the value of the global variables b_ref
  and s_mat

RETURN VALUE

  The result returned is of the type form_factor
  It returns an array of three complex (type ki) corresponding
  to the real part, imaginary part of the coefficient in front 1/epsilon^2,
  the real part, imaginary part of the 1/epsilon term and the real part,
  imaginary part of the constant term.

NAME

  Function a10_s

USAGE

  type(form_factor) = a10_s(set)

DESCRIPTION

 This function defines the form factor A^{1,0}.

INPUTS

 * set -- an array of integers of rank 1 corresponding to the label 
          of the propagators pinched (removed from the original set
          which is in the global variable set_ref)

SIDE EFFECTS

  No side effect

RETURN VALUE

  The result returned is of the type form_factor
  It returns an array of three complex (type ki) corresponding
  to the real part, imaginary part of the coefficient in front 1/epsilon^2,
  the real part, imaginary part of the 1/epsilon term and the real part,
  imaginary part of the constant term.
