These are the modules: \begin{description} \item[blha\_config] \item[blha\_interface] \item[blha\_driver] \end{description} @ %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \section{Module definition} These modules implement the communication with one loop matrix element providers according to the Binoth LesHouches Accord Interface. The actual matrix element(s) are loaded as a dynamic library. This module defines the common OLP-interfaces defined through the Binoth Les-Houches accord. <<[[blha_olp_interfaces.f90]]>>= <> module blha_olp_interfaces use, intrinsic :: iso_c_binding !NODEP! use, intrinsic :: iso_fortran_env use kinds <> use constants use numeric_utils, only: vanishes use numeric_utils, only: extend_integer_array, crop_integer_array use io_units use string_utils use physics_defs use diagnostics use os_interface use lorentz use sm_qcd use interactions use flavors use model_data use pdg_arrays, only: is_gluon, is_quark use prclib_interfaces use process_libraries use prc_core_def use prc_core use prc_external use blha_config <> <> <> <> <> <> contains <> end module blha_olp_interfaces @ %def module blha_olp_interfaces @ <>= public :: blha_template_t <>= type :: blha_template_t integer :: I_BORN = 0 integer :: I_REAL = 1 integer :: I_LOOP = 2 integer :: I_SUB = 3 integer :: I_DGLAP = 4 logical, dimension(0:4) :: compute_component logical :: include_polarizations = .false. logical :: switch_off_muon_yukawas = .false. logical :: use_internal_color_correlations = .true. real(default) :: external_top_yukawa = -1._default integer :: ew_scheme contains <> end type blha_template_t @ %def blha_template_t @ <>= procedure :: write => blha_template_write <>= subroutine blha_template_write (blha_template, unit) class(blha_template_t), intent(in) :: blha_template integer, intent(in), optional :: unit integer :: u u = given_output_unit (unit) write (u,"(A,4(L1))") "Compute components: ", & blha_template%compute_component write (u,"(A,L1)") "Include polarizations: ", & blha_template%include_polarizations write (u,"(A,L1)") "Switch off muon yukawas: ", & blha_template%switch_off_muon_yukawas write (u,"(A,L1)") "Use internal color correlations: ", & blha_template%use_internal_color_correlations end subroutine blha_template_write @ %def blha_template_write @ Compute the total number of used helicity states for the given particle PDG codes, given a model.

The subtractions terms can be pure Born matrix elements (to be used in collinear subtraction or in internal color-correlation), color-correlated matrix elements or spin-correlated matrix elements. The numbers should be ordered in such a way that $\mathcal{V}_{\rm{fin}}$ is first, followed by the pure Born, the color-correlated and the spin-correlated matrix elements. This repeats $n_{\rm{flv}}$ times. Let $\nu_i$ be the position of the $ith$ virtual matrix element. The next $\mathcal{V}_{\rm{fin}}$ is at position $\nu_i = \nu_{i - 1} + n_{\rm{sub}} + 1$. Obviously, $\nu_1 = 1$.
