apfelgrid
- Ebuilds: 1, Testing: 1.0.5 Description:
The APFELgrid plugin is a tool designed to accelerate the computation of physical observables at hadron colliders, by means of combining the interpolated weight-grids provided by the APPLgrid project with the evolution of parton densities provided by APFEL. The tool is aimed at PDF fitting groups, as it allows for the extremely rapid recalculation of cross-sections when varying the input PDF.
APFELgrid generates FastKernel (or FK) tables which reduce the computation of NLO pQCD predictions to a particuarly compact form in terms of PDFs at a single initial scale.

apfelxx
- Ebuilds: 1, Testing: 4.8.0 Description:
APFEL++ is a C++ rewriting of the Fortran 77 evolution code APFEL. However, APFEL++ is based on a completely new code design and guarantees a better performance along with a more optimal memory management. The new modular structure allows for better maintainability and easier extensibility. This makes APFEL++ suitable for a wide range of tasks: from the solution of the DGLAP evolution equations to the computation of deep-inelastic-scattering (DIS) and single-inclusive-annihilation cross sections. Also more complex computations, such as differential semi-inclusive DIS and Drell-Yan cross sections, are easily implementable in APFEL++.

atompaw
- Ebuilds: 1, Testing: 4.1.1.0 Description:
An utility for Projectors Augmented Waves dataset generation.
PAW calculations require, for each atomic species, a set of basis (partial-waves) and
projectors functions plus some additional atomic data stored in a PAW dataset. A PAW
dataset has to be generated in order to reproduce atomic behavior as accurately as possible
while requiring minimal CPU and memory resources in executing the DFT code for the
crystal simulations. These two constraints are conflicting.
The code, originally written by N. A. W. Holzwarth, A. R. Tackett, and G. E. Matthews,
is described in the publication A Projector Augmented Wave (PAW) code for electronic
structure calculations, Part I: atompaw for generating atom-centered functions, Computer
Physics Communications 135 329-347 (2001). With the help of several collaborators
at Wake Forest University as well as several international collaborators, the code
has been continually updated and adapted for use with various electronic structure codes
including abinit, quantum-espresso, socorro, and pwpaw.

genfit
- Ebuilds: 2, Testing: 9999 Description:
GENFIT is an experiment-independent framework for track reconstruction for
particle and nuclear physics. It consists of three modular components:
- Track fitting algorithms
Currently, GENFIT contains a Kalman Filter and a
Deterministic Annealing Filter.
Other algorithm modules can be added easily.
- Track representations
These modules hold the data of track track parameters and can perform
extrapolations of these parameters.
GENFIT is distributed with two well-tested track representations.
Existing track extrapolation codes can be interfaced in a very
straightforward way in this framework, using their native geometry
and magnetic field interfaces.
- Reconstruction hits
The hit dimensionality and the orientation of planar tracking detectors
can be chosen freely.
GENFIT is especially useful for tracking systems which include detectors
which do not measure the passage of particles on predefined planes,
like TPCs or wire-based drift chambers. The concept of so-called
virtual detector planes provides a simple mechanism to use these
detector hits in a transparent way without any geometrical simplifications.
GENFIT has been developed in the framework of the PANDA experiment at
FAIR, Darmstadt, Germany.
It is also used in the Belle-2, Fopi, and GEM-TPC experiments.

nll-fast
- Ebuilds: 1, Testing: 3.1 Description:
NLL-fast is a computer program which computes the squark and gluino hadroproduction cross sections including next-to-leading order (NLO) supersymmetric QCD corrections and the resummation of soft gluon emission at next-to-leading-logarithmic (NLL) accuracy. NLL-fast also provides an estimate of the theoretical uncertainty due to scale variation and the parton distribution functions. The program reads in grid files with NLO and NLO+NLL results, the scale uncertainty and the pdf and alphas error and uses a fast interpolation routine to provide predictions for any value of squark and gluino masses in the mass ranges specified below. The results for the LHC collision energy of 13 TeV can be obtained with the latest 3.1 version, whereas earlier 2.1 (1.2) versions deliver cross sections for 8 (7) TeV. Results are obtained with the MSTW2008NLO (MSTW2008LO for the LO results), the CTEQ6.6M (CTEQ6L1) pdfs, and for version 3.1 also with the NNPDF3.0NLO (NNPDF3.0LO) set. Results for selected processes of squark and gluino production for 14, 33, and 100 TeV collision energy are also available in NLL-fast, see below.

NNLL-fast is a computer program which computes the squark and gluino hadroproduction cross sections including approximate next-to-next-to-leading order (NNLOApprox) supersymmetric QCD corrections and the resummation of soft gluon emission at next-to-next-to-leading-logarithmic (NNLL) accuracy, including the resummation of Coulomb gluons with a NLO Coulomb potential and bound-state contributions below the production threshold. NNLL-fast also provides an estimate of the theoretical uncertainty due to scale variation, the parton distribution functions, and the value of the strong coupling αs. The program reads in grid files with NLO and NNLOApprox+NNLL results, the scale uncertainty and the PDF and αs error and uses a fast interpolation routine to provide predictions for any value of squark and gluino masses in the mass ranges specified below. The results are provided for the latest LHC collision energy of 13.6 TeV for Run 3, and will be updated for future runs of the LHC. The predictions are created with the recent PDF4LHC21_40_pdfas PDF sets.

- Ebuilds: 2, Testing: 4.0.5 Description:
The code calculates the SUSY spectrum using low energy data and a user supplied high scale model as input. The spectrum is used to calculate two- and three body decay modes of supersymmetric particle as well as of Higgs bosons. In addition the production cross sections for supersymmetric particle and Higgs bosons in e^+ e^- annihilation is calculated. Moreover, the branching of the decay $b \to s \gamma$, the SUSY contribution to anomalous magnetic moment of the muon as well as the SUSY contributions to the rho parameter due to sfermions are calculated. The code is written in F90 with an emphasis on easy generalisability. The structure is set such that complex phases as well as the extension to include the flavour structure can be done in a straight forward way. The 2-loop renormalization group equations as well as the one-loop finite corrections a la Bagger, Matchev, Pierce and Zhang are included. In addition the two-loop corrections to the neutral Higgs boson masses (a la Brignole, Degrassi, Slavich and Zwirner) and to the mu-parameter (a la Dedes and Slavich) are included. Starting with version 2.2.2 the SUSY Les Houches Accord is supported as well as the SPA conventions (for details see hep-ph/0511344).

whizard
- Ebuilds: 2, Testing: 3.1.6 Description:
WHIZARD is a program system designed for the efficient calculation of multi-particle scattering cross sections and simulated event samples.
WHIZARD can evaluate NLO QCD corrections in the SM for arbitary lepton and hadron colliders. Tree-level matrix elements are generated automatically for arbitrary partonic processes by using the Optimized Matrix Element Generator O'Mega. Matrix elements obtained by alternative methods (e.g., including loop corrections) may be interfaced as well. The program is able to calculate numerically stable signal and background cross sections and generate unweighted event samples with reasonable efficiency for processes with up to eight final-state particles; more particles are possible. For more particles, there is the option to generate processes as decay cascades including complete spin correlations. Different options for QCD parton showers are available.
Polarization is treated exactly for both the initial and final states. Final-state quark or lepton flavors can be summed over automatically where needed. For hadron collider physics, an interface to the standard LHAPDF is provided. For Linear Collider physics, beamstrahlung (CIRCE) and ISR spectra are included for electrons and photons. The events can be written to file in standard formats, including ASCII, StdHEP, the Les Houches event format (LHEF), HepMC, or LCIO. These event files can then be hadronized.
WHIZARD supports the Standard Model and a huge number of BSM models. Model extensions or completely different models can be added. WHIZARD fully supports external models from UFO files. There are also legacy interfaces to FeynRules and SARAH.

xfitter
- Ebuilds: 1, Testing: 2.2.0 Description:
Proton parton distribution functions (PDFs) are essential for precision physics at the LHC and other hadron colliders. The determination of the PDFs is a complex endeavor involving several physics process. The main process is the lepton proton deep-inelastic scattering (DIS), with data collected by the HERA ep collider covering a large kinematic phase space needed to extract PDFs. Further processes (fixed target DIS, ppbar collisions etc.) provide additional constraining powers for flavour separation. In particular, the precise measurements obtained or to come from LHC will continue to improve the knowledge of the PDF.
The xFitter project is an open source QCD fit framework ready to extract PDFs and assess the impact of new data. The framework includes modules allowing for a various theoretical and methodological options, capable to fit a large number of relevant data sets from HERA, Tevatron and LHC. This framework is already used in many analyses at the LHC.
