src/form_factor/form_factor_1p [ Modules ]
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 ]
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.

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.
